Allan was sitting hunched over at his desk, with a strong light shining on it. Acrid smoke curled up while he worked. He was concentrating so hard that he didn't hear Malmani come in.

"Hey Allan! Your door was open and-- Ancestors! What are you doing? What is that smell?" Malmani took two steps back and coughed.

Allan looked up, startled. "Oh, sorry, I didn't hear you come in Malmani. The smell? Oh, hold on a second, sorry." He flipped a switch next to his desk and a powerful fan over his desk started, and pulled the acrid smoke away. "I was trying to solder together this board and was concentrating so hard. These surface mount components are super tough to do on their own."

As the air cleared, Malmani was able to take a closer look. Eyes watering, she noticed that he had two little clamps on his desk and they were holding a thin wafer of green plastic with...small protrusions dotted all over it.

She flicked her ear and said "What are you making? It looks like a miniature city"

Allan looked down at the PCB and chuckled "Hah, it does, doesn't it? I'm trying to make a new kind of environmental sensor. The ones we have are really bulky and fail often." He realized that they were of K'laxi make and that he was talking to a K'laxi and quickly added "Er, sorry, I mean that I was thinking about the design while I was trying to repair one last week and started daydreaming about making it better."

"It's fine Allan, it's fine. I'm not insulted." Malmani thought for a moment. "At least, I don't think I'm insulted. I was just wondering what you were doing, and now I know. But why?"

"Like I said, the ones in place are bulky. I think I can make one that's more compact. Maybe even one that's more accurate. Plus, it's fun to do."

"Fun?"

"Sure! I like thinking about electronics and how they work and how you could optimize things and make it better."

"So Starbase didn't ask you to make it, you're just making it because you want to?"

"Yup. Starbase and I have been collaborating on the design though. They're letting me know what things they wish were easier to read."

"That's right Mal." Starbase chimed in "Allan was asking me about the environmental sensors, and I had mentioned how it's tough for me to get a holistic view of an area since the sensors don't talk to each other - just to me - so first thing he's doing is adding a local network connection. They should be able to talk to each other and send a more unified picture of what's going on."

Allan nodded "Yeah, see these bits right here?" He gestured with a small plastic stick. "These are the mesh networking components. They are what will let them talk to each other. We're also going to try a human sourced environmental sensor. We make ours a different way, and I think it'll be smaller and faster to refresh. I'm keeping a lot of the K'laxi wiring though, your resistors and capacitors are incredibly efficient. I've already requested a couple boxes of K'laxi components, I want to see how well they mesh with human ones."

Mal shook her head. "I can't get over how you're just designing a new component for Starbase just because. I don't think I would have ever thought to do that."

Allan shrugged. "It's just the way I'm wired I guess. I don't think it's a human-only thing. After all, K'laxi built the whole entire Starbase without us, you have to have your own people who like to tweak and tinker, right?"

Mal thought a moment. "There must be some K'laxi like that because you're right. But I don't know if it's as..." She struggled for word "...as prevalent as it is with Humans? Most of the time, once we have a solution that works, we leave it in place until we have a need for a change. Iterating just for iterations sake doesn't come as naturally to us."

Allan nodded. "Looking at the components in place, I can tell."

Mal flicked an ear.

"Er, I mean that a lot of the comments are perfectly good at doing their job, but they look like that once a workable solution was found people stopped. In a bunch of human components you come across solutions that are elegant, or ones that utilize as few components as possible, or solutions that are the cheapest they could be, things like that." Allan thought for a moment. "I wonder if it has to do with our world? Earth is a lot more dangerous than K'lax right? Maybe we are always trying to find an edge, because that would give us just a little bit more breathing room in case of a disaster."

"Huh Maybe. Anyway, I was coming in to remind you that this week it's your turn to buy the snacks for tonights board game."

"Oh! That's right, that is tonight. Starbase, I'll have to stop here and we can pick it up tomorrow after work okay? I'm almost ready to install the firmware and have you connect and tell me." He stopped "How it feels I guess?"

"That's fine Allan, I'll be here."

I repaired this sick ass digital clock I got from a thrift store very cheaply a few years ago. It's just a floating LCD panel and I think it looks so frigging amazing. (Really makes me think of that cool Dutch YouTuber, Posy, and his love of LCD panels. (And I'm like "hell yeah!! There's so much beauty in the mundane!!! Just look how frigging cool this clock is!!"))

Anyhoo, it wasn't working when I got it. Probably why it was so cheap.

It has a little on/off switch on the back, but nothing would happen when you flipped it, but sometimes if you held its solar panel under a very bright light the clock would turn on

...for one second

before turning off again

and then back on again.

Very rhythmically.

So there was still some life left in the old girl... somewhere... 🤔

Unscrew the back of it and have a look see.

Discover a pair of circuit boards, one of which has a cr2032 coin cell clamped onto it. Hooray, a Vital Clue!

Fortunately, I have one of those batteries lying around. A second spare from when I replaced the batteries in some Digimon v-pets.

So I replace it.

Aaaaand nothing happens...

:(

Next step: fully disassemble the clock to look for More Clues.

Discover that its LCD panel isn't wired in to anything. There's just a row of teeny tiny contacts along its base which press up against a matching row of teeny tiny contacts along its control board, held together by the frame of the clock and a kind of thin pink foam buffer ring around the contacts. Very cool!

(Like two mouths kissing but only one of them has any lips. 😆)

Examine the two circuit boards under a loup. Maybe there's a visibly-broken component!

(I hope there's a visibly-broken component, else I have to dig out my multimeter and start systematically testing them one by one)

(I hope there aren't any visibly-broken components. If it's the quartz crystal or one of the two capacitors, then I might be able to replace it, because those are regular-sized, through-hole, components; but if it's one of the surface-mount resistors then I'd have to scrap the whole clock, because I just don't have the tools, experience, or know-how to deal with those microscopic little guys... :/ )

There aren't any visibly-broken components. Phew, but also consternation, because now what?

But hmm, there are some teeeeny tiny white flecks of crusty residue here and there over the circuit boards... I guess the old battery must have leaked at some point?

I gently scrape them off with the tip of a very fine pair of tweezers and then reassemble the clock enough to test it.

(LCD panel & solar panel back into front-frame, control board back over them to hold them into place and make contact with the LCD; everything else [coin-cell daughterboard, piezo buzzer, and the user-input buttons] dangling free in the breeze Winnie-The-Pooh-style)

It turns on! It chirps out a happy little song of high-pitched beeps!! It blinks "12:00" at me!!!

I fully reassemble the clock with a song in my heart and set its time and date.

Goddamn this clock looks so cool. 🥰

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.

📞 = surface mount resistor ?!

[circuitcardassembly]

What is Circuit Card Assembly and Why is it Crucial for PCB Board Production?

A Circuit Card Assembly (CCA), too known as PCB Board Assembly or PCBA Circuit Board, speaks to a vital breakthrough in electronic manufacturing where components are mounted onto a printed circuit board (PCB) to make a useful electronic gadget. This prepare changes a uncovered PCB into a working electronic assembly that powers everything from smart phones to mechanical machinery.

The travel of circuit card assembly starts with a uncovered PCB, which serves as the establishment for all electronic components. Amid the Assembly handle, different electronic components counting resistors, capacitors, coordinates circuits, and chip are carefully put and patched onto the board concurring to the plan details. This change from a straightforward PCB to a completely useful PCBA circuit board includes a few advanced steps and technologies.

Surface Mount Technology (SMT) plays a significant part in advanced circuit card Assembly. This strategy permits components to be specifically mounted onto the surface of the PCB, empowering higher component thickness and more compact plans. The SMT handle ordinarily starts with applying patch glue to particular areas on the board through a stencil, taken after by exact arrangement of components utilizing robotized pick-and-place machines. These machines can position thousands of components per hour with surprising accuracy.

Through-hole Technology, in spite of the fact that more seasoned than SMT, remains crucial in PCB board assembly, particularly for components that require more grounded mechanical associations or require to handle higher control loads. This strategy includes embeddings component leads through pre-drilled gaps in the PCB and fastening them on the inverse side, making vigorous associations that can withstand mechanical stress.

Quality control speaks to a basic viewpoint of circuit card Assembly. Each PCBA circuit board experiences thorough testing methods, counting automated optical inspection (AOI), X-ray assessment for covered up patch joints, and utilitarian testing to guarantee all components work as expecting. These quality measures are basic since indeed minor surrenders can lead to gadget failure.

The significance of exact circuit card assembly in PCB board generation cannot be exaggerated. To begin with, it straightforwardly impacts the unwavering quality and execution of the last electronic item. A well-assembled board guarantees legitimate electrical associations, warm administration, and flag judgment, all pivotal for gadget functionality.

Additionally, proficient circuit card Assembly makes a difference minimize electromagnetic impedances between components, which is basic in today's thickly stuffed electronic gadgets. Appropriate component arrangement and steering amid PCBA Circuit Board Assembly offer assistance keep up flag keenness and decrease commotion, guaranteeing ideal performance.

The financial suggestions of quality circuit card assembly are noteworthy. Appropriate Assembly diminishes the hazard of field disappointments, guarantee claims, and item returns, eventually sparing producers significant costs. Besides, effective assembly forms offer assistance optimize generation throughput and diminish time-to-market for modern electronic products.

As gadgets proceed to advance with expanding complexity and miniaturization, the part of circuit card assembly gets to be indeed more basic. Present day PCB board assembly must suit progressed components like ball grid arrays (BGAs), quad flat no-leads (QFN) bundles, and other complex coordinates circuits whereas keeping up tall unwavering quality and abdicate rates.

Looking ahead, circuit card Assembly proceeds to progress with unused technologies and strategies. Automated assembly lines, manufactured intelligence-driven quality control, and progressed materials are pushing the boundaries of what's conceivable in PCBA circuit board manufacturing, empowering the generation of progressively modern electronic gadgets that control our cutting edge world.

Got the taillights done for my new Go Kart!

More pics and explanation under the cut:

Haven't made up my mind yet if it would look better with the retroreflector cut even smaller so the trim with the "screw heads" from the original ride-on toy could be seen around it. I think I'll leave it be like this.

Homemade pcb has surface mount red LEDs and two input wires run through different value current limiting resistors for "dim" and "bright" (running lights and brake lights/turn signals, respectively) signaling. Diodes on inputs protect from back-feeding.
