On Bodging Silly Mistakes

After a few weeks of rest and working on non-homebrew-related projects since getting my 68030 stack running 8-user BASIC, I've circled back around to the project. My goal is to have it ready to exhibit for VCF Southwest 2025 in June.

The first thing to do when picking up an old project is to make sure it still works to begin with.

It did not.

The computer would start up, go through its boot process, and start the user programs. The supervisor terminal would accept and execute commands, but none of the user terminals would accept input.

I could tell the serial data was making it to the machine, because my 8-port serial card has indicator LEDs on the Transmit & Receive signals and they were working as expected. If I held down a key as the system booted, it would print that character a few times before stopping and then no longer accept any more data. So it really looked like the hardware was working. Nothing had changed in software so that wasn't likely to be the issue.

It reminded me of the problems I encountered with reading from disk when CPU cache was preventing the updated disk status bit from being read. The serial card supports asserting the CPU's Cache Inhibit signal, but perhaps that circuit wasn't functioning. There was no change with it connected or not. Time to break out the oscilloscope. The Cache Inhibit signal was always low — always asserted. Cache wasn't the problem because cache was effectively always disabled.

Out of ideas, it was time to break out the logic analyzer. The I/O Read & Write signals on the serial card were working as expected, and it was properly addressing the card & its individual ports. So next thing was to check was the actual data being read from the UARTs.

Letting the logic analyzer run and watching the data fly through, the problem finally made itself known — the UARTs were not setting bit 0 of the status byte to indicate that they had received data. The data was getting to the UART, it just wasn't acknowledged.

But why? And why did it work initially on restart and then stop? And why did it work without issue a few weeks ago? What is different?

What is different, indeed. I have made one change to the hardware since I last ran it — I added a proper watchdog/power-on-reset controller. If the power supply drops below 4.7 volts, it will reset the computer. The power supply I had been using was marginal and was getting caught by the watchdog, so I switched to a proper power PC supply.

So what's different since last time I ran the system is my reset circuit is more effective and the system voltage should be much more stable 5V.

And that's when I realized a mistake I made in the design for my 8-port serial card. The 68k reset signal is active-low and the 16C55x UART reset signal is active-high. I was trying to minimize part count, and didn't have an inverter for the reset signal, so I used what I had on hand — a buffer with an active-low enable signal.

Anyone well-versed in electronics may already see the problem.

When the CPU-RESET# signal is asserted (low), the buffer will set its output, IO-RESET to match its input, VCC (high). That's great, we get a high signal on the output whenever the CPU Reset signal is low.

Except ... what happens when the CPU Reset signal is not asserted? The buffer goes open-collector and doesn't pull the IO-RESET signal one way or the other; it's just left floating.

Floating signals are bad news for digital circuits. Their behavior is unpredictable and subject to environmental noise, power fluctuations, etc. For my IO-RESET signal to function properly, something needs to pull it low whenever the 74'125 buffer is not actively driving it high. A good-sized pull-down resistor should do the job just fine, so I dug through my stock and found a 3.65k surface-mount resistor and bodged it onto the back side of the board.

And sure enough, that fixed the problem!

It is possible that when I was running the system on that marginal power supply previously, the IO-RESET signal was able to stay just low enough to not trigger reset on the UARTs. Or it could have just been different environmental factors.

I'm glad I took the time to test the machine today, and I'm glad this bug came up. It's the kind of bug that could easily have come up when running in a new environment for the first time — such as on the show floor at VCFSW. Far better to run into a bug like this at home with access to all of the tools (and time) to figure it out.

Now that things are up and running again I can continue my testing and setup for VCFSW.

[kalikai]

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.

Smart Tweezers ST5S:

All-in-One Design: Smart Tweezers combine a set of high-precision SMD probes and a digital multimeter into a single handheld device. This streamlined design simplifies testing and eliminates the need for separate probes and multimeters.

Automatic Component Identification: One of the standout features of Smart Tweezers is their ability to automatically identify and evaluate SMD components. This saves time and reduces the risk of human error. The device can recognize resistors, capacitors, and inductors.

Ergonomic and Portable: Smart Tweezers are easy to handle and operate with one hand. Their lightweight and ergonomic design make them a preferred choice for professionals and hobbyists alike.

Real-Time Measurement: These tweezers provide real-time measurements, allowing users to monitor changes in component values as they troubleshoot. There's no need to disconnect and reconnect probes repeatedly.

LCD Display: Smart Tweezers feature a clear LCD display that shows component values and measurement results. It's easy to read and interpret, even in low-light conditions.

Conventional Multimeter:

Multiple Components: A conventional multimeter typically consists of separate probes and a central unit. It can measure a wide range of electrical parameters, including voltage, current, resistance, capacitance, and more.

Manual Range Selection: Conventional multimeters often require users to manually select the appropriate measurement range and function. This can be time-consuming, especially when testing various components.

Limited SMD Testing: While multimeters are versatile, they are less suitable for testing surface mount devices (SMDs) without the use of additional adapters or fixtures. This can add complexity to SMD troubleshooting.

Complex Readings: Interpreting multimeter readings can be challenging, especially for beginners. Users must understand the correct units, ranges, and measurement modes.

In summary, Smart Tweezers ST5S are a specialized tool tailored for SMD component testing, offering automatic identification and real-time measurements in a compact and user-friendly form. They are ideal for users who frequently work with SMDs. On the other hand, conventional multimeters are versatile devices suitable for a wide range of electrical measurements but may require additional tools for SMD testing.

The Importance of High-Quality PCB Manufacturing Services for Advanced Electronics

Electronics have become an integral part of nearly every industry. From smartphones to medical devices, automotive systems to consumer gadgets, high-quality PCBs (Printed Circuit Boards) are essential to the functionality and performance of these products. As the heart of any electronic device, PCB board manufacturers and PCB manufacturing companies play a crucial role in ensuring that devices work reliably and efficiently. This article will explore the importance of high-quality PCB manufacturing services, with a particular focus on PCB board manufacturers, PCB assembly manufacturers, and PCB assembly in advanced electronics.

Why High-Quality PCB Manufacturing Services Matter

High-quality PCB manufacturing services are fundamental to the development of advanced electronic devices. These services encompass the entire process, from initial design and prototyping to the fabrication, assembly, and testing of PCBs. For any electronic product to function properly, the PCB must be carefully manufactured with precision, reliability, and durability in mind.

In high-end devices, even minor defects in the PCB can lead to malfunctioning products, costly recalls, or safety issues. Therefore, choosing a reputable PCB manufacturing company that specializes in high-quality PCB fabrication is essential. These companies use advanced technologies, strict quality control procedures, and high-performance materials to ensure the final product meets stringent specifications.

The Role of PCB Board Manufacturers

PCB board manufacturers are the cornerstone of the entire PCB production process. They are responsible for translating designs into physical boards by layering materials, etching copper traces, and drilling holes. The accuracy of these steps is critical because any errors can compromise the integrity of the entire circuit. High-quality manufacturers use precision equipment and modern techniques such as laser drilling, automated optical inspection (AOI), and multi-layer stacking to create complex and reliable PCBs.

Moreover, PCB board manufacturers can offer customization based on specific project requirements. Whether it's for a simple single-layer PCB or a more intricate multi-layer design, these manufacturers ensure that the boards are tailored to meet the exact needs of the device they will power.

The Importance of PCB Assembly Manufacturers

Once the PCBs are fabricated, the next step in the process is PCB assembly, where electronic components such as resistors, capacitors, and microchips are placed onto the board. PCB assembly manufacturers play a vital role in ensuring that these components are placed correctly and soldered securely. An error in this stage can result in malfunctioning electronics, which can be costly to repair and replace.

PCB assembly manufacturers must be adept at handling both surface-mount technology (SMT) and through-hole technology to meet the demands of modern electronic devices. Using automated pick-and-place machines, these manufacturers place components onto the boards with high precision, followed by soldering using reflow ovens or wave soldering machines. The goal is to create a flawless, functional assembly that can endure wear and tear during product use.

Quality Control and Testing in PCB Manufacturing

One of the key elements of high-quality PCB manufacturing services is rigorous testing. PCB assembly manufacturers use various methods to test the functionality and reliability of the assembled board. Techniques such as automated optical inspection (AOI), X-ray inspection, and electrical testing ensure that there are no hidden defects in the PCB.

These quality control measures are especially important in industries such as aerospace, automotive, and medical electronics, where failure can have catastrophic consequences. By employing comprehensive testing procedures, manufacturers can identify issues early and ensure that only the most reliable and durable PCBs make it to the market.

Conclusion

The importance of high-quality PCB manufacturing services cannot be overstated in the production of advanced electronics. PCB board manufacturers, PCB manufacturing companies, and PCB assembly manufacturers all contribute to ensuring that PCBs meet high standards of precision, reliability, and performance. As technology continues to evolve, the demand for complex, high-quality PCBs will only increase. By selecting a trusted and experienced PCB manufacturing partner, businesses can ensure that their electronic products are built on a solid foundation of reliable circuit boards, minimizing defects and maximizing performance.

Whether you're designing the latest consumer electronics, medical devices, or industrial machinery, investing in high-quality PCB manufacturing services is crucial to the success of your product.

Understanding PCB SMT and Placas de Circuitos: The Heart of Modern Electronics

In today’s high-tech world, electronics are everywhere—from smartphones and laptops to industrial machines and medical devices. At the core of these devices lies a crucial component: the PCB (Printed Circuit Board). When combined with SMT (Surface Mount Technology), it becomes a powerful system for building compact, reliable, and efficient electronic products. In many Spanish-speaking regions, these are referred to as "placas de circuitos" or "placas electrónicas", essential in every electronic product's design and performance.

What is a PCB?

A PCB is a board made from insulating material, typically fiberglass, with conductive pathways etched or printed onto it. These pathways connect various electronic components like resistors, capacitors, and integrated circuits (ICs), enabling them to communicate and function as a unit. PCBs can range from simple single-layer designs to complex multi-layer structures used in advanced applications.

In Spanish, this board is known as a “placa de circuito impreso” or “placa de circuitos”, and it forms the physical and electrical foundation for assembling electronic systems.

What is SMT?

Surface Mount Technology (SMT) is a method used to mount electronic components directly onto the surface of a PCB. Unlike older methods that required drilling holes into the board for component leads, SMT places components on the surface, making the process faster, more accurate, and more suitable for automated assembly lines.
