CC ORIGIN STORY by @lubedoo

Hello! I’ve been following your art for some time and really enjoy it! I especially like the Tails and CC threads and have been mulling just how CC came to be and how she first met Tails, given the brief outlines you’ve published. I scribbled out the first chapter of a fan fiction expanding on CCs origins which I hope you’ll like. Let me know what you think… I can write more if you like it. Hope to see more of Tails and CC soon either way!

Chapter 1: Walter’s Widgets

“No, this won’t work… the gear pitch is misaligned to the functional plane!”

The camera aperture on the small robot’s spindly head focused in and out on the tiny interlocking mechanism as its grouchy furred boss pointed at the offending interface with thin metal pick. Its pincer-like hands reached for the device, but it was quickly snatched away. The robot retreated a few feet on its wheelbase at the sudden movement.

“It has to be at the correct angle or it will bind and fail prematurely!” He looked sternly at the two droids standing in front of him, the second a more squat construction containing a platform and several manipulators. “Assembler, you have the steady table and precision arms. Can’t you work with Gear Placer to match these up?”

Assembler responded in a series of low hums and groan-like noises, while Gear Placer rattled off high-pitched squeals and beeps.

“Wait, whoa… one at a time.” The old woodchuck removed his glasses and grasped the bridge of his nose. “I can understand both of you but not when you talk over each other. Didn’t the interface chips I installed help with translating your machine languages?”

Gear Placer reached a pincer inside an opening in its head and plucked out a small circuit board, which clearly had been overtaxed. The melted wires and burn marks were testament to its overuse and failure. Assembler groaned about its being in a similar condition, but was unable to remove it given its location.

The woodchuck sighed as he examined the ruined electronics. “I suppose that’s what I get for cobbling you all together from different control boards and drivers. I never expected my Widget business to be so complex.”

Walter Woodchuck had built WW Widgets into a local phenomenon. It started as a hobby business, building little devices for himself and his friends in his garage workshop. But word spread about his clever and unique designs, and suddenly customers were sending in requests from as far as Reclusivia. It provided him with a nice retirement income and kept him busy for sure, but he knew he needed help if he was to keep building these devices to his exacting standards.

And Walter was by no means a “people person.” He tried hiring a few Mobian assistants but none lasted very long. He was very particular in how he wanted things done, and few of his hired help was willing (or able) to keep up with his demands. Even his nephew William could only last for short stints in the WW manufacturing area before needing a periodic “sabbatical.”

So Walter decided with the size and scope of his business to move out of the tiny garage and into a “Fabratory” he had built towards the back corner of his property. It was a moderately sized but impressive facility that functioned as a device development lab, a manufacturing floor, a warehouse, and a store front. The store was more of an Automat, with remote payment devices and clear-doored cubbies where his customers could pay for and retrieve their items. It was very rare that any of them met with or even saw Walter… and he liked it that way. There was even a small living space so he could spend as much time as he wanted in his own little world. He would send one of the robots for supplies as needed, and the store owners in town knew Walter was good for payment.

But as with Walter and the outside world, communication among his robots was severely lacking. He built them as the need arose, from Circuit Solderer to Chip Mounter and Metal Stamper to Test Aligner. Their names were childish but functional, as Walter didn’t see the need to personalize his creations, only to have them do their job as they were told. And since they were constructed over time, the parts available to build them varied as did their internal machine languages, resulting in a maddening (to Walter) Production Line of Babel. The robots understood everything Walter told them but little of what the others twittered and beeped. They were still effective in producing wonderful Widgets, but frequently also manufactured a lot of stress for Walter.

Walter turned back to Gear Placer and Assembler, impatiently explaining to each what needed to be fixed on the device they had presented. They both excitedly responded in their own languages and raced off to fix their mistake.

“There has to be an easier way,” the tired woodchuck grumbled. “Maybe if I built another robot, one that could understand all their code and interpret for them… and me…” His voice trailed off as he turned to his drafting table and began drawing up yet another design.

After a few hours of intense thought and technical sketching (and with a few interruptions from the Production floor), he looked at his newest blueprint. “Yes, this should do nicely. I’m sure Oscar has the proper processors, auditory inputs, and servo impellers to make this happen. It will be my most advanced creation yet. I’ll need it to be able to learn, accept and provide feedback, and adapt to our design changes.” His brow furrowed. “This is going to be somewhat expensive, but that latest Widget order from Spagonia should cover the cost. Well worth it.”

He looked over the plans again and leaned back in his chair. Walter crossed his arms, smiled, and relaxed a bit. “Yes, you will be a great help to me… Code Compiler.”

-----

Evay: Wow, this is amazing! Oh I sincerely hope you do write more! I know I've been neglectful in all of the details of CC's origin. I promise I do have a script written for a comic for her, but I love when you all take the initiative and interpret how you think things went. It's an absolute delight for me 🥰 I really enjoyed this read and I look forward to more. Thank you so much!

What is PCB Assembly ?

PCB Assembly manufacturer - Hitech Circuits Co., Limited

It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It’s these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology“. The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Generally, this technique employs the use of state of the art machines, which are fully automatic. For example, the surface mount components are worth positioning with the aid of an automated pick and place machine.

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques

This method is favorite for use with through-hole parts, which needs manual placement on the board. Besides, with these through-hole parts, it’s advisable you use wave soldering. Note that in the through- hole assembly process, you need to place the components and electronics on the PCB.

After that, you use wave soldering to solder the leads. Typically, you will need an individual to insert a component into a marked PTH. Once done, transfer the PCB to the next station where the next person will be on standby tasked with fixing another part.

What are the Benefits of SMT PCB Assembly?

SMT assembly provides many benefits and some of them are as follows:

It can be used to incorporate small components.

In SMT, the components can be placed on both sides of the board.

It assures high component densities.

Fewer holes need to be drilled for surface mounting than through-hole.

It require low initial costs and time for setting up the mass production.

SMT is the simpler and faster-automated assembly when compared to through-hole.

Errors regarding the component placement can be easily rectified.

Surface mount PCBs feature strong joints, which can easily withstand vibrations.

What are the techniques used in Surface Mount Technology?

There are several techniques for the reflow process. After applying the solder paste or a flux mixture on the board and after placing the components, the boards are conveyed to a reflow soldering oven. The techniques used for reflowing soldering include infrared lamps, hot gas convection, fluorocarbon liquids with a high boiling point, and so on.

What are the different testing methods used in SMT PCB Assembly?

Hitech Circuits as the PCB assembly manufacturer, we perform the following testing and inspection to ensure the quality of surface mount PCBs.

Automated Optical Inspection (AOI): This is performed before and after the soldering to identify the component placement, presence, and solder quality.

X-ray Testing: In this type of testing, the operator relies on the X-ray images of the PCB to check the solder joints and lead-less components such as Quad Flat Packs and ball grid arrays, which are generally not visible to naked eyes.

In-Circuit Testing (ICT): This method is used to detect manufacturing defects by testing the electrical properties in the SMT Assembly.

What type of files or documents should I send for SMT PCB Assembly?

Gerber Files: The file contains all details of physical board layers including solder masks, copper layers, drill data, legends, and so on.

Bill of Materials (BOM): This contains information on the list of items needed for the PCB manufacturing and the instructions of manufacturing.

Pick and Place File: This file contains information on all components to be used in the PCB design and their rotation and X-Y coordinates.

The whole process of PCB Assembly

1. Bare board loader machine

The first step in the PCB assembly is to arrange the bare boards on the rack, and the machine will automatically send the boards one by one into the SMT assembly line.

2. Printing solder paste

When PCB on the SMT production line, firstly, we have to print solder paste on it, and the solder paste will be printed on the pads of the PCB. These solder pastes will be melt and solder the electronic parts to the circuit board when it passes through the high-temperature reflow oven.

In addition, when testing new products, some people will use film board/adhesive cardboard instead of solder paste, which can increase the efficiency for adjusting the SMT machines.

3. Solder paste inspection machine(SPI)

Since the quality of solder paste printing is related to the quality of welding of subsequent parts, some SMT factories will use optical machine to check the quality of solder paste after printed the solder paste in order to ensure stable quality. If there any poorly printed solder paste board, we will wash off the solder paste on it and reprint, or remove the excess solder paste if there is redundant solder paste on it.

4. High speed SMT machine

Usually, we will put some small electronic parts (such as small resistors, capacitors, and inductors) to be printed on the circuit board first, and these parts will be slightly stuck by the solder paste just printed on the circuit board, so even if the speed of printing is very fast and the parts on the board will not fall away. But large parts are not suitable for use in such high speed SMT machines, which will slow down the speed of small parts assembly. And the parts will be shifted from the original position due to the rapid movement of the board.

5. Universal SMT machine

Universal SMT machine is also known as "slow machine", it will be assembled some large electronic components, such as BGA IC, connectors, etc., these parts need more accurate positions, so the alignment is very important. Use a camera to take a picture to confirm the position of the parts, so the speed is much slower than High speed SMT machine we taked before. Due to the size of the components here, not all of them are packed in tape and reel, and some may be packed in trays or tubes. But if you want the SMT machine to recognize the trays or tube-shaped packaging materials, you must configure an additional machine.

Generally, traditional SMT machines are using the principle of suction to move electronic parts, and in order to place the parts successfully, and there must be the flat surface on these electronic components for the suction nozzle of the SMT machine to absorb. However, for some electronic parts don’t have a flat surface for these machines, and it is necessary to order special nozzles for these special-shaped parts, or add a flat tape on the parts, or wear a flat cap for thees electronic parts.

6. Manual parts or visual inspection

After assembled all parts by the high speed SMT machine or Universal SMT machine and before going through the high-temperature reflow oven, and we will set up a visual inspection station here and to pick out the deviation parts or missing components boards etc., because we have to use a soldering iron to repair if there are still defectives boards after passing the high-temperature oven, which will affect the quality of the product and will also increase the cost. in addition, for some larger electronic parts or traditional DIP parts or some special reasons cannot be processed by the SMT machine before, they will be manually placed on pcb here.

7. Reflow oven

The purpose of reflow oven is to melt the solder paste and form a non-metallic compound on the component feet and the circuit board, that means to solder electronic components on the circuit board. The temperature rise and fall curves often affect the soldering quality of the entire circuit board. According to the characteristics of the solder materials, usually the reflow oven will set the preheating zone, soaking zone, reflow zone, and cooling zone to achieve the best soldering effect.

For example, the melting point for SAC305 solder paste with lead-free is about 217°C, which means that the temperature of the reflow oven must be higher than the melting points to remelt the solder paste. What's more, the maximum temperature in the reflow furnace should not exceed 250°C, otherwise many parts will be deformed or melted because they cannot withstand such a high temperature.

Basically, after the pcb passed through the reflow oven, the assembly for the entire circuit board is almost complete. If there are hand-soldered parts, we need to transfer to DIP process, and then we have to check the quality after reflow oven by QC department.

8. Automatic optical inspection(AOI)

The main purpose of setting up AOI is because some high density boards can’t be process the following ICT test, so we used AOI inspection to replace it. But even using AOI inspections, there still have the blind spots for such checking, for example, the solder pads under the components cannot be checked by AOI. At present, it can only check whether the parts have side standing issue, missing parts, displacement, polarity direction, solder bridges, lack of soldering etc., but cannot checking the BGA solderability, resistance value, capacitance value, inductance value and other components quality, so far AOI inspection can’t completely replace ICT test.

Therefore, there is still some risk if only AOI inspection is used to replace ICT testing, but ICT test is also not 100% make sure the good quality, we suggest these two ways can be combined with together to make sure the good quality.

9. PCB unloader machine

After the board is fully assembled, it will be retracted to the unloder machine, which has been designed to allow the SMT machine to automatically pick and place the board without damaging the quality for PCB.

10. Visual inspection for finished products

Normally there will be a visual inspection area in our SMT production line whether there is an AOI station or not, and it will help to check if there are any defectives after completed assembled the pcbs. If there is an AOI station, it can reduce the visual inspection worker on our SMT line, and to reduce the potential cost, and because it is still necessary to check some places that cannot be judged by AOI, many SMT factories will provide the mainly visual inspection templates at this station, which is convenient for visual inspection worker to inspect some key parts and polarity for components.

11. DIP process

DIP process is a very important process in the whole PCBA processing, and the processing quality will directly affect the functional for PCBA boards, so it is necessary to pay more attention to the DIP process. There are many preliminary preparations for DIP process. The basic process is to re-process the electronic components first, like to cut the extra pins for some DIP components, our staff received the components according to the BOM list, and will check whether the material part numbers and specifications are correct or not, and performs pre-production pre-processing according to the PCBA samples. The steps are: Use various related equipment (automatic capacitor pins cutting machine, jumper bending machine, diode and triode automatic forming machine, automatic belt forming machine and other machines) for processing.

12. ICT test

Printed Circuit board open/short circuit test (ICT, In-Circuit Test), The purpose of ICT test is mainly to test whether the components and circuits on the printed circuit board are open or short issues. It can also measure the basic characteristics of most components, such as resistance, capacitance, and inductance values to judge whether the functions of these parts are damaged, wrong parts or missing parts etc. after passing through the high-temperature reflow oven.

ICT test machines are divided into advanced and basic machines. The basic ICT test machines are generally called MDA (Manufacturing Defect Analyzer). It’s just to measure the basic characteristics of electronic components and judge open and short circuits issue we talked above.

In addition to all the functions of the basic ICT test machines, for advanced ICT test machine can also test the whole PCBA by using power, start to testing the PCBA boards by setting the program in the test machine. The advantage is that it can simulate the function of the printed circuit board under the actual power-on condition, this test can partly replace the following functional test machine (Function Test). But the cost for the test fixture of this advanced ICT test can probably buy a car, it’s too expensive and we suggest it can be used in mass production products.

13. PCBA function test

Functional testing is to make up for the ICT test, because ICT only tests the open and short circuits on the the PCBA board, and other functions such as BGA and other fuctions are not tested, so it is necessary to use a functional testing machine to test all functions on the whole PCBA board.

14. Cutting board (assembly board de-panel)

Normally, printed circuit boards will be produced in panel, and it will be assembled to increase the efficiency of SMT production. It means several single boards in one panel, such as two-in-one, four-in-one etc. After finished all the pcb assembly process, it needs to be cut into single boards, and for some printed circuit boards with only single boards also need to cut off some redundant board edges.

There are several ways to cut the printed circuit board. You can design the V-cut using the blade cutting machine (Scoring) or directly manually break off the board (not recommended). For more high density circuit boards, it will be used the professional splitting machine or the router to split the board without any damage the electronic components and printed circuit boards, but the cost and working hours will be a little longer.

Consumer Electronics PCB Assembly Manufacturer

[email protected]

The Leading Chinese Consumer PCB & Assembly Supplier

The Leading Chinese Consumer PCB & PCB Assembly Supplier

It was common for white goods devices, brown goods devices, and smart toys to have simple, rigid boards with 1-4 layers in the past of years. Today’s consumer PCB products have become more portable. They use more complicated HDI PCB boards (at least 6 layers), flexible and stiff-flex boards. These consumer PCB applications have high-tech requirements for PCB manufacturers. For consumer PCB projects, thousands of electronic engineers choose Hitech Circuits.

We can help you get your consumer electronics projects “from design to manufacturing”

We are the best Chinese consumer PCB (circuit board manufacturer) because of our 24-hour rapid response service from our tech support and sales team. Hitech Circuits can help you with any questions about consumer PCBs. Please feel free to contact us at any time.

What Is Consumer PCB ?

Simply put, consumer PCB refers to the PCB used in consumer products like smartphones, smart TV and smart watches.

The demand for consumer PCBs has been growing ever since consumer PCBs were first introduced in the 1980s. Even small school projects or college projects use consumer PCBs nowadays.

In general, PCBs are boards on which circuit diagrams are physically implemented, so they can be used by devices easily.

As with a printer, it prints a copy of the original document or image on paper if you give it something. Likewise, the machine will print your PCB design on a board made mainly out of plastic, glass fiber, or some other materials if you upload it into it.

Most wiring is done by using a copper-coated track. Baseboards for flex PCB and rigid-flex PCB will be made from different materials to allow them to be semi- or fully flexible.

The Advantages and Disadvantages of Consumer PCBs

Before you buy consumer PCBs, here are some things you need to know:

The Advantages of Consumer Printed Circuit Board

● Compact Size and Saving of Wire: The copper tracks on the PCB make it possible to interconnect the components. The copper tracks replace the current carrying wires, resulting in a less bulky interconnection, permitting the components to be very small.

● Ease of Repair and Diagnostic: On consumer PCBs, it is easier to verify and replace a particular component that has failed. In properly designed boards, the components have clear polarity labels. Thus, convenience can be assured during both the installation and repair processes. During diagnostics, signal paths can easily be traced.

● No Short Circuits: Short circuiting of the whole device is impossible thanks to the material used in the manufacturing of PCBs. When one part stops working, then you are able to replace it with another identical part. This makes it easier to keep it going without worrying about all the other components being damaged.

● Time Savings: In the conservative technique of circuit connections, the components take a long time to connect. On the other hand, As compared to conventional circuit connections, printed circuit boards take comparatively less time to assemble.

● Immune to Movement: Each component on a printed circuit board is tightly held onto the board.

They are prevented from moving on the board by the solder flux essence, regardless of how the board moves.

● Tight Connections: Copper tracks make sure that connections are made automatically. It is very unlikely that any loose connections will occur during this process.

● Low Electronic Noise: In a properly laid out printed circuit board, the noise from the electronics will be reduced. If the layout is not done properly, then there is a high chance that the noise will hinder the circuit’s performance.

On PCBs, electrical components are organized in a way so that the current path lengths between them are as less as possible.

This means that electromagnetic waves and radiation are picked up. This means that there is less crosstalk between components and between traces. This is often a concern in electronic systems. Electrical noise can come in the form of heat, radiation, or flickering sounds.

● Low Cost: With a high demand for circuits boards, large-scale production of these PCB circuits boards is guaranteed at low costs, which means you will save on both costs and time.

● Reliability: All of the above translate to reliability in the circuit’s performance.

● Streamlined Production: Before PCB prototypes are ready for use, they need to go through a lengthy testing process. This because each issue must be examined individually and dealt with by hand. An automated design check alerts the designer to potential problems during the engineering process.

This intuitive design process means that PCBs often move into production more quickly than PTP constructions because testers know what to look for.

The Disadvantages of Consumer PCBs:

● Hard Repairing Process: It is very difficult to repair a damaged PCB, especially if traces or vias have been damaged. It is best to replace the entire board rather than repair it.

● Specific Usability: There are specific reasons for designing consumer PCBs, they cannot be used for other purposes or functions. A PCB should be designed for the purpose it will be used for, otherwise it might cause problems if it’s later changed.

● Environmental Pollution: As a result of different chemicals used in PCB manufacturing that are not good for the environment, the process of manufacturing PCBs is not environmentally friendly. Consumer PCBs are not recyclable and are mainly made from plastic like materials that pollute.

● Limited Application Area: Due to copper tracks’ thinness, consumer PCBs are only capable of carrying a limited current, so PCBs are only suitable for areas with low current requirements.

Consumer PCB Prototyping

Multiple runs are often required to test new designs or to verify a single function before moving to a more complicated design. So engineers use PCB prototypes in the early stages of design to verify the functionality of a PCB-based system. Prototyping helps in predicting success and avoiding failure for the consumer PCB. Consumer PCB prototypes are easy to produce and have a quick turnaround time. You can also detect flaws quickly. Prototyping allows you to test individual components in your room. This allows for efficient project completion by providing an accurate representation of the standard PCB performance. This helps to reduce overall project costs by allowing the designer to fix flaws earlier. There is a better final product at the end of all this.

Previously, this site also introduced some knowledge about the parent machine. Today we continue to continue Let me introduce the role of the parent line machine without contribution.

The parent line supply bus price | Supplier | Quotes Parallel placing mechanism from the literal understanding is that the direction of the line is in a parallel position. Under the processing mode of flat lines and multi -wire and wound, it is characterized by small space. The mechanism is equipped with a sliding brake or pneumatic brake as a tension generator, which is generally configured in the medium and large bus.

After mechanical transmission, the servo system also requires that the servo system has excellent static and dynamic load characteristics, that is, when the servo system changes in different load conditions or by winding conditions, the main axis is constant. Because the CNC bus has put forward strict technical requirements for the servo system, the servo system also puts forward strict requirements for its own specialized servo motor:

The self-powered sensor automatically harvests magnetic energy - Technology Org

New Post has been published on https://thedigitalinsider.com/the-self-powered-sensor-automatically-harvests-magnetic-energy-technology-org/

The self-powered sensor automatically harvests magnetic energy - Technology Org

MIT researchers have developed a battery-free, self-powered sensor that can harvest energy from its environment.

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings of a ship’s engine. There, it could automatically gather data on the machine’s power consumption and operations for long periods of time.

The researchers built a temperature-sensing device that harvests energy from the magnetic field generated in the open air around a wire. One could simply clip the sensor around a wire that carries electricity — perhaps the wire that powers a motor — and it will automatically harvest and store energy which it uses to monitor the motor’s temperature.

“This is ambient power — energy that I don’t have to make a specific, soldered connection to get. And that makes this sensor very easy to install,” says Steve Leeb, the Emanuel E. Landsman Professor of Electrical Engineering and Computer Science (EECS) and professor of mechanical engineering, a member of the Research Laboratory of Electronics, and senior author of a paper on the energy-harvesting sensor.

In the paper, which appeared as the featured article in the January issue of the IEEE Sensors Journal, the researchers offer a design guide for an energy-harvesting sensor that lets an engineer balance the available energy in the environment with their sensing needs.

The paper lays out a roadmap for the key components of a device that can sense and control the flow of energy continually during operation.

The versatile design framework is not limited to sensors that harvest magnetic field energy, and can be applied to those that use other power sources, like vibrations or sunlight. It could be used to build networks of sensors for factories, warehouses, and commercial spaces that cost less to install and maintain.

“We have provided an example of a battery-less sensor that does something useful, and shown that it is a practically realizable solution. Now others will hopefully use our framework to get the ball rolling to design their own sensors,” says lead author Daniel Monagle, an EECS graduate student.

Monagle and Leeb are joined on the paper by EECS graduate student Eric Ponce.

John Donnal, an associate professor of weapons and controls engineering at the U.S. Naval Academy who was not involved with this work, studies techniques to monitor ship systems. Getting access to power on a ship can be difficult, he says, since there are very few outlets and strict restrictions as to what equipment can be plugged in.

“Persistently measuring the vibration of a pump, for example, could give the crew real-time information on the health of the bearings and mounts, but powering a retrofit sensor often requires so much additional infrastructure that the investment is not worthwhile,” Donnal adds. “Energy-harvesting systems like this could make it possible to retrofit a wide variety of diagnostic sensors on ships and significantly reduce the overall cost of maintenance.”

A how-to guide

The researchers had to meet three key challenges to develop an effective, battery-free, energy-harvesting sensor.

First, the system must be able to cold start, meaning it can fire up its electronics with no initial voltage. They accomplished this with a network of integrated circuits and transistors that allow the system to store energy until it reaches a certain threshold. The system will only turn on once it has stored enough power to fully operate.

Second, the system must store and convert the energy it harvests efficiently, and without a battery. While the researchers could have included a battery, that would add extra complexities to the system and could pose a fire risk.

“You might not even have the luxury of sending out a technician to replace a battery. Instead, our system is maintenance-free. It harvests energy and operates itself,” Monagle adds.

To avoid using a battery, they incorporate internal energy storage that can include a series of capacitors. Simpler than a battery, a capacitor stores energy in the electrical field between conductive plates. Capacitors can be made from a variety of materials, and their capabilities can be tuned to a range of operating conditions, safety requirements, and available space.

The team carefully designed the capacitors so they are big enough to store the energy the device needs to turn on and start harvesting power, but small enough that the charge-up phase doesn’t take too long.

In addition, since a sensor might go weeks or even months before turning on to take a measurement, they ensured the capacitors can hold enough energy even if some leaks out over time.

Finally, they developed a series of control algorithms that dynamically measure and budget the energy collected, stored, and used by the device. A microcontroller, the “brain” of the energy management interface, constantly checks how much energy is stored and infers whether to turn the sensor on or off, take a measurement, or kick the harvester into a higher gear so it can gather more energy for more complex sensing needs.

“Just like when you change gears on a bike, the energy management interface looks at how the harvester is doing, essentially seeing whether it is pedaling too hard or too soft, and then it varies the electronic load so it can maximize the amount of power it is harvesting and match the harvest to the needs of the sensor,” Monagle explains.

Self-powered sensor

Using this design framework, they built an energy management circuit for an off-the-shelf temperature sensor. The device harvests magnetic field energy and uses it to continually sample temperature data, which it sends to a smartphone interface using Bluetooth.

The researchers used super-low-power circuits to design the device, but quickly found that these circuits have tight restrictions on how much voltage they can withstand before breaking down. Harvesting too much power could cause the device to explode.

To avoid that, their energy harvester operating system in the microcontroller automatically adjusts or reduces the harvest if the amount of stored energy becomes excessive.

They also found that communication — transmitting data gathered by the temperature sensor — was by far the most power-hungry operation.

“Ensuring the sensor has enough stored energy to transmit data is a constant challenge that involves careful design,” Monagle says.

In the future, the researchers plan to explore less energy-intensive means of transmitting data, such as using optics or acoustics. They also want to more rigorously model and predict how much energy might be coming into a system, or how much energy a sensor might need to take measurements, so a device could effectively gather even more data.

“If you only make the measurements you think you need, you may miss something really valuable. With more information, you might be able to learn something you didn’t expect about a device’s operations. Our framework lets you balance those considerations,” Leeb says.

“This paper is well-documented regarding what a practical self-powered sensor node should internally entail for realistic scenarios. The overall design guidelines, particularly on the cold-start issue, are very helpful,” says Jinyeong Moon, an assistant professor of electrical and computer engineering at Florida State University College of Engineering who was not involved with this work. “Engineers planning to design a self-powering module for a wireless sensor node will greatly benefit from these guidelines, easily ticking off traditionally cumbersome cold-start-related checklists.”

Everything You Need To Know About Welding Reels

Welders use welding reels to join two or more pieces of metal, plastic, or other material. Welding reels come in various sizes and shapes to fit the needs of different welders. The most common type of welding reel is the round-headed reel. There are also some square-headed welders and grapples.

What are welding reels?

Welding reels are devices used to connect two pieces of metal. They come in a variety of sizes, and they can be used for both welding and soldering. Cox welding reels are also sometimes used to connect different metals in various ways, such as in a production line.

Types of welding reels

There are many different types of welding reels, with each one designed for a specific purpose. Here are some of the most common types:

· Hydraulic welding reel: This type of reel is used to attach pieces of metal using hydraulic power. It’s often used in joinery and other metalworking tasks.

· Electric welding reel: This type of reel is used to attach pieces of metal using an electric current. It’s often used for heavy-duty repairs and weldING sessions.

· Magnetic welding reel: This type of reel is especially popular among welders because magnets can easily control it. It’s also helpful when attaching items to supports or other objects.

Benefits of using welding reels

Welding reels come in various shapes and sizes, each with benefits for the welders. Here are some of the most common benefits of using welding reels:

-They are easy to use - A welding reel is typically small and easy to carry around, making it perfect for more minor welds.

-They are quick - Welder's reels tend to be very quick, allowing you to complete your welds quickly and efficiently.

-They are accurate - Welder's reels are often very accurate, allowing you to achieve the correct size welds with little error.

How to choose the right welding reel for your project

Choosing the right reel for your project is important when you're looking to weld. A wrong choice can lead to expensive repairs and a slower, more difficult weld. To ensure you select the right reel for your project, read through this section and find out what welding equipment you need and how best to use it.

Three types of welding reels are fixed-gear, geared, and belt-driven. Fixed-gear reels are typically used for larger, more complex projects, while geared reels offer faster welds but can be less reliable in certain circumstances. Belt-driven Welding Reels are perfect for smaller tasks as they allow you to control the speed of the welds by using belts or other means. They also tend to be less durable than other welding reels, so be careful when working with them on delicate materials.

When choosing a diamond lead reels, it’s also important to consider the size of your project. It would help if you chose a large reel to cover all your equipment and protect your work area from damage. You should also choose an easy-to-reuse reel, mainly if you have limited experience welding with traditional wire fences or clamps. Finally, ensure that the Welding Reel you choose is compatible with your specific welding software - many machines now come built with Welding Reels (though some older ones may not).

Tips for using a welding reel

Welding reels are one of the most common tools used by welders. They come in various shapes and sizes and can be used for manual and automatic welding. Here are some tips to help you use a welding reel effectively:

1. Make sure the reel is filled adequately before beginning welding. It will ensure that the welds being created are directed correctly and have minimal stress on the system.

2. Be sure to read the instructions that accompany your welding reel before starting work. Often, these will include specific tips on using the reel for optimal results.

3. Use caution when using a welding reel in areas with a high potential for sparks or fire. Always wear eye protection and follow safety guidelines when working with any tool!

How to use a welder with a welding reel

When using a welder with a welding reel, always follow these safety tips:

1. Keep the welder and reel clean.

2. Use proper hand and eye coordination when welding.

3. Wear a hard hat and protective clothing while working with the welder.

4. Stay calm and aware of your surroundings while welding.

Conclusion

Welding reels are a vital part of any welding project. They provide the user with stability and accuracy while welding and can save time and money. Many different types of welding reels are available on the market, so it's important to choose the right one for your project. By reading this article, you'll better understand what they are, how they function, and what benefits they offer.

PCB Assembly Board

What is PCB Assembly ?

PCB Assembly manufacturer - Hitech Circuits Co., Limited

[email protected]

1. Surface-mount technology

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques
