Printed Circuit Board Basics
Most of us are using Printed Circuit Board in our daily life. Printed Circuit Boards are used in almost all the Electronic products, from consumer gadgets such as PCs, tablets, smartphones, and gaming consoles to industrial and even high tech products in strategic and medical electronics domains.
Here, we have some statistics for you that shows how many electronic devices connect worldwide from 2015 to 2025. This statistic shows an increase in the use of a number of PCB in people daily life. Hence, CircuitWala took this opportunity to provide a basic knowledge about PCB via this article.
There are so many books available online which teach about Printed Circuit Board design and hardware part. There are few links available online which shows only a few basic fundamentals of PCB and few are there for Basics of Printed Circuit Board (PCB) Design. Few which gives good know knowledge on Printed Circuit Board terminology. But in the end for the hobbyist, there is no such material available which make their work easy.
Now days there few online designing websites available which allow hobbyist and students to create their design and Printed Circuit Board fabrication part. These websites provide limited features and charge high for the full edition. We, @CircuitWala are in try to provide one platform which provides plenty of Printed Circuit Board knowledge digitally to make your work simple and easy.
Alternatives of PCB include wire wrap and point-to-point construction. Creating a layout of PCB is a little bit time-consuming method as compared to its alternative solution but manufacturing of PCB is cheaper and faster then other wiring methods as electronic components are mounted and wired with one single part.
Let’s start with some basics of Printed Circuit Board with this article. Here in this article we will discuss about history of PCB to understand the emerge of PCB, Types of PCB to make your complex PCB a very simple using different types, Usage of PCB to provide you an idea to create more Printed Circuit Board projects, Advantages and Disadvantages, Possible Future to know about new technological change in Printed Circuit Board manufacturing and also about how to destroy and manage your PCB’s e-waste? We know you are eager to know all the stuff in details but before that let’s make a simple definition of Printed Circuit Board.
What is Printed Circuit Board?Printed Circuit Board is an electronic device made of conductive material(FR-4) like copper which connects components mounted on it to to get desired output by providing an input on another end.
When the board has not mounted with any of the components is called as Printed Circuit Board or Printed Wired Board. Mounting of an electronic component on Printed Circuit Board is called as PCB assembly.
History of Printed Circuit BoardThe invention of Printed Circuit Board was by Austrian engineer Paul Eisler as part of a radio set while working in England around 1936.
In early days before Printed Circuit Board became common in use, Point-to-Point construction was used. This meant some bulky and unreliable design that required plenty of sockets and regular replacement of it. Most of this issue directly address when PCB went into regular production.
Originally, every electronic component had wire leads, and the PCB had holes drilled for each wire of each component. The components’ leads were then passed through the holes and soldered to the PCB trace. This method of assembly is called Through-Hole construction. There is one other method to mount component is called as Surface Mount.
Type of Printed Circuit BoardPCBs are produced from the different types of material and on the basis of that material PCBs are divided mainly into two parts: Rigid PCB and Flexible PCB. Nowadays, a combination of Rigid and flexible PCB is also possible and that is called as Flexi-Rigid PCBs.
Most of the PCBs are built in layers. The inner layer is the base material called as a substrate. Rigid PCBs are mainly made of material like epoxy materials and Flexible PCBs are made of plastic material that can withstand high temperatures.
Rigid PCBs are generally, hard materials that hold the component in a better way. The motherboard in the tower of a computer is the best example of Rigid PCBs. Flexible PCBs fundamental material allows PCB to fit into forms that Rigid PCBs can not. Flexible PCBs can turn round without harmful the circuit on PCB.
All Rigid and Flexible PCBs can come in three formats by layers: Single Layer, Double Layer, and Multi-Layer.
1. Single Layer PCBSingle Layer PCBs have been around since the late 1950s and still dominate the world market in sheer piece volume. Single Sided PCBs contain only one layer of conductive material and are best suited for low-density designs. Single-sided PCBs are easy to design and quick to manufacture. They serve as the most lucrative platform in the industry.
2. Double Layer PCBDouble Layered printed circuit board technology is conceivably the most popular type of PCB in the industry. Double Sided PCB (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to advanced technology applications. They allow for a closer (and perhaps more) routing traces by alternating between top and bottom layers using vias.
3. Multi Layer PCB
Multilayer PCB is a circuit board that has more than two layers. Unlike a Double-Sided PCB which only has two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material which are buried in the center of the material.
Usage of Printed Circuit BoardBy reading this article till this point, we hope that you are now able to get about printed circuit boards. Now, we will make you understand about different applications of printed Circuit Board.
In this digital world, Printed Circuit Board is in almost all our daily life electronic devices and in our industrial electronics as well. Below are the industries where PCBs are used:
Possible FutureNowadays, most of the circuits are replaced to produce Printed Circuit Board from the old methods. Revolution in technology made many of the processes automated and hence it is easy to manufacture PCB. But still, these processes are a bit expensive to hire, involve toxic waste and use high temperatures and acids. With technological advances we have seen in the past years, it is not hard to imagine PCB will soon be revolutionized. Not only that but research institutes predict a more ‘green’ future for PCBs; PCBs being made of paper.
Electronic Waste (e-waste)Electronic Waste or e-waste is described as discarded electrical or electronic devices. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.
Electronic scrap components contain a hazardous substance such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and communities in developed countries and great care must be taken to avoid unsafe exposure in recycling operations
Nowadays, developing countries are encouraging electronic users to take care while recycling the e-waste or submit them to the organization who are involved in such activities.
SummaryIn this blog, we have learned the basics of Printed Circuit Board. CircuitWala is planning to write as many blogs to provide more and more knowledge of Printed Circuit Board. Either it is basics or manufacturing or usages or advantages and disadvantages of PCBs. We will also try to make our users/customers up to date for the new technology innovations, including past histories and revolution of the PCB industries.
In the next blog, we will look at more briefly about the different types of Printed Circuit Board. We also understand the process to make it and different usage and application for the same.

Understanding Circuit Board Electronic Components: A Comprehensive Guide
In today's digital world, electronic devices have become an essential part of our daily lives. But what makes these devices tick? At the heart of every electronic device lies a circuit board—a masterpiece of tiny electronic components working together to perform complex tasks. In this article, we’ll dive deep into the fascinating world of circuit board electronic components, exploring each element’s role and how they contribute to the overall functionality of the device.
What is a Circuit Board?
A circuit board, often referred to as a PCB (Printed Circuit Board), is a flat board used to mechanically support and electrically connect various electronic components. These components work in unison to perform a specific task. Think of the circuit board as the skeleton and nervous system of an electronic device—it holds everything together and allows communication between parts.
Types of Circuit Boards
Single-sided PCB: Has one layer of conducting material.
Double-sided PCB: Contains two layers for components and connections.
Multi-layer PCB: Complex boards with multiple layers for advanced applications.
The Role of Electronic Components on a Circuit Board
Every electronic device you interact with is powered by a carefully designed circuit board filled with various components. These components might be tiny, but each one has a critical role in the operation of the device. Here's a breakdown of the most important electronic components you’ll find on a typical circuit board.
1. Resistors
Resistors are fundamental components that control the flow of electrical current. They resist the flow of electrons, hence the name "resistor." Their primary function is to reduce current flow, adjust signal levels, and divide voltages in a circuit. Without resistors, circuits would allow too much current to flow, potentially damaging other components.
Types of Resistors
Fixed resistors: Have a set resistance value.
Variable resistors: Allow adjustment of the resistance.
2. Capacitors
Capacitors store and release electrical energy in a circuit. They are often compared to small rechargeable batteries that quickly charge and discharge. Capacitors help smooth out fluctuations in voltage, filter noise, and store energy for future use.
Common Uses of Capacitors
Energy storage
Signal filtering
Voltage stabilization
3. Inductors
Inductors are components that store energy in a magnetic field when electrical current flows through them. They resist changes in current and are typically used in circuits to filter signals, manage power, and store energy.
Applications of Inductors
Power supplies
Radio frequency circuits
Noise suppression in circuits
4. Diodes
A diode is like a one-way valve for electricity, allowing current to flow in only one direction. They are vital in circuits to prevent reverse currents, which can damage components.
Types of Diodes
Light-emitting diodes (LEDs): Produce light when current flows through.
Zener diodes: Regulate voltage within a circuit.
5. Transistors
The transistor is a versatile component used to amplify or switch electronic signals. In essence, transistors are like tiny switches that turn signals on and off rapidly, making them essential in modern electronics.
Types of Transistors
NPN transistors: Allow current flow when a small voltage is applied to the base.
PNP transistors: Conduct when the base is negatively charged.
How Circuit Board Components Work Together
In a circuit, each component has a specific role, and together they form a cohesive system. For example:
Capacitors and resistors may work together to filter signals or smooth out voltage fluctuations.
Transistors and diodes ensure that signals are amplified or directed properly.
Integrated circuits handle the complex tasks, processing data, and controlling the overall system.
Choosing the Right Components for Your Circuit Board
When designing or repairing a circuit board, choosing the correct components is crucial. Some factors to consider include:
Voltage requirements
Power consumption
Signal type and frequency
Physical size and compatibility
Conclusion
Circuit boards are an integral part of any electronic device. The various components on the board each play a specific role in ensuring the device functions as intended. Understanding these components, from resistors to integrated circuits, is essential for anyone working with electronics, whether you're designing a new system or troubleshooting an existing one.

Wrap030-ATX Says "Hellorld"
Tumblr media
In the immortal word of [Usagi Electric], Wrap030-ATX says, "Hellorld". This can only mean one thing — serial I/O is working!
Getting serial working should be relatively straightforward. The UART I'm using is an 8-bit peripheral which needs a Chip Enable and an Output Enable signal, just like the ROM. It's a little slower, so it will need an extra wait state or two, but it should be easy enough to modify the bus controller state machine to address the UART as well. It didn't take me long to add the necessary logic, solder on the new parts, and fire it up for a test run.
Nothing happened.
I went through all the normal steps — double check the wiring, make sure my test leads haven't come loose, make sure the chip is seated properly in its socket and not shorted out …
… I burned my finger. And not just a little 'ow that's a bit warm to the touch', but a proper second-degree burn. That UART chip was hot.
That kind of heat can only mean there is a direct short somewhere in the chip. It could just be a defective part, but since they are out of production and I only have a few on hand, the best thing to do is confirm the problem isn't on my board somewhere before trying another one (and potentially destroying it too).
The PCB layout passed Design Rule Check, so I didn't have any overlapping traces. The schematic didn't have any obvious errors where maybe I had inadvertently tied an output signal to power or ground. This was not an existing library part — it was one that I had to create — so it was possible I had gotten pin assignments wrong.
I pulled up the datasheet and opened the part in the library and started confirming all of the pin assignments matched the datasheet. Bus & I/O pins were all fine; but the very last power supply pin was assigned to Vcc, where the datasheet had it marked Vss. So I had a +5V power supply capable of sourcing in excess of 25A of current running into what should have been a ground pin. No wonder it was hot enough to burn; it's a wonder it didn't release the magic smoke immediately.
This is a challenge. I need to swap a power pin for a ground pin on a PLCC socket. On a simpler project, I might've gotten away with just cutting the trace running to that pin and soldering a bodge wire to it.
… But this is a 4-layer board. There is no mere trace running to that pin — there is an entire inner layer attached to it. My best bet would probably be removing the offending pin from the socket, but depending on how it's constructed, I may not be able to remove the pin.
Tumblr media
Through-hole PLCC socket pins are staggered. Some go straight down through the board, but alternating pins make an L-shape so that the socket can have two rows of through-hole pins at a 0.1" grid spacing. The L-shaped pins would be trapped under the plastic base of the socket.
Luckily, the pin in question was the first on its side, so it went straight through the base. I started by bending up its contact, and then with the heat turned up on my soldering iron, I was able to pull it out of the board and completely free from the socket.
Tumblr media
I had some wire on hand that was just the right width to match the slots for the contacts in the socket. I bent a flat loop to make contact with the chip lead and shoved it down into the slot. It worked perfectly. I ran it over to a nearby jumper that had a ground lead, and there I have my first bodge wire for this project.
It still didn't work.
This is the part of debugging that is the most frustrating. There's a problem and it takes a considerable amount of effort to identify not just the cause, but also the solution. And then after working through those steps and finally implementing a fix, it still doesn't work because there is another problem. Back to square 1 with debugging.
Why is it not working? It's not burning hot, so that problem was indeed solved. I'm getting data to the chip, and the read/write strobes are functional. The chip select signals are ... wait, why isn't chip select working?
... Because I forgot a chip, that's why. Insert Picard facepalm GIF here.
The UART I'm using is a Western Digital WD16C552. It's a lovely chip designed for 386 era PCs contain two 16550-compatible UARTs and a Centronics Parallel port as well. It is three peripherals in one package. To save I/O on my bus controller CPLD, I used a 74'139 2-to-4 decoder to further break down the address for this serial/parallel I/O chip into the three specific peripheral select signals I needed. And I simply forgot to solder that chip onto the board.
Two headers and one 74LS139 later and finally my terminal came to life. The Wrap030-ATX whispered its very first greeting, "HELLORLD". Serial I/O is working and I can move on to the next step. And oddly enough, I tested that first chip that flirted with fire and it actually still works!
I am racing forward through the countless tests and steps to bring this machine to life ahead of VCF Southwest at the end of June. I am hoping to get it at least running BASIC over serial by that time, but for that I am going to need some RAM. This will be fun because this is my first time actually building a DRAM controller; I've done some test designs before but never actually built them. Fingers crossed I don't run into any show-stopping errors getting it up and running.

another new toy
Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media
I've been planning to get a number of accessories for my new computer. A new monitor, microphone, maybe one of those vr headsets. But after having it for a few weeks, one thing jumped out as needing an upgrade more urgently than anything else - the stock full size keyboard that came with it was just too large and awkward for my little keyboard shelf. I was tempted to go back to the Microsoft Compact Bluetooth keyboard that I was using with the Steam Deck... but I haven't had a "real" computer, like a proper desktop computer in decades, I wanted a "real" keyboard to go with it. Like a proper mechanical keyboard with switches and buttons and such. And so I typed "mechanical keyboard reviews" into a youtube search, blissfully unaware of the rabbit hole I was about to fall down.
If you know then you already know, but it came as a surprise to me that membrane keyboards are so cheap and so easy to mass produce that they've taken over the casual market altogether, forcing mechanical keyboards into the domain of the ⋆ ˚。⋆˚enthusiast⋆ ˚。⋆˚
Yes, it seems proper keyboards are a hobby now, not a very cheap one either, and the very last thing I need is another expensive hobby. But every hobby has its more affordable and approachable on ramps, and there are a number of pre-built budget boards occupying this space in world of mechanical keyboards. After watching a few dozen hours of youtube videos and reading a bunch of reviews and tutorials, I eventually settled on the RK84 'limited edition' from Royal Kludge for us$80. Which is like twice what I expected to pay when I in my naive innocence began shopping for keyboards, but I've come to understand that eighty bucks absolutely counts as "budget" in this hobby.
Pricing aside, I really do love my new keyboard. The 75% form factor is ideal, better centering the typing keys and saving a bunch of extra space on my little shelf while maintaining all the functionality of a full size board save only for the number pad. While I do like to use a number pad, I don't mind taking one out when I need it, and the keyboard even has a couple usb ports to easily plug a mouse and separate number pad into, which is super convenient and such an obvious idea that I really have to wonder why all keyboards aren't doubling as USB multi-dongles at this point, with additional usb ports, sd card ports, and so on.
For $10 more than the regular RK84 wireless, the 'limited edition' version has better keycaps, factory-lubed switches, some filler foam in the housing to reduce the hollow sound, an additional layer of sound dampening foam sandwiched between the top plate and the pcb, and a snazzy color scheme, the version I chose combining a black body and mostly black keys with a white top plate that better reflects the swirly rainbow rgb backlighting. The sound is decent, at least to my untrained ear, right out of the box. Which is ideal, as I'd like to avoid the temptation to start modding it.
Because I've gone about as far down this particular rabbit hole as I want to go.
Though I suppose it is tempting to open it up, as some basic tape & band aid mods would be cheap and easy and might improve the sound a bit...
And as much as the pre-lubed yellow linear switches are nice, I did make sure to get a hot-swappable board so it's easy to change them out later if I want to try alternatives, and I do think I might prefer tactile switches for typing...
And the rgb lighting is nice enough that it really is a shame these caps aren't shine though. Yeah, yeah, shine-through is tacky, but Cringe is Dead, and some black top pudding caps might really make the lighting pop. Or maybe a mix of black, white and some accent color to match the color layout that the board came with?
The abyss, it tempts me so...

The difference between copper base PCB, fake double-sided copper base PCB and true double-sided copper base PCB
Copper base PCB is the best heat dissipation and the most expensive circuit board among metal-based PCBs. Generally, copper base PCB include single-sided copper PCB, double-sided copper base PCB, and fake double-sided copper base PCB. The specific advantages of copper base PCB make them widely used in areas with large changes in high and low temperatures, as well as in the precision communication equipment and LED car light markets. The pad production processes of copper substrate manufacturers generally include immersion gold, OSP, HASL, immersion silver, etc.
Authenticity of true and false double-sided copper base PCB
Fake double-sided copper base PCB are generally designed by customers with two layers of circuits, but they are not connected to each other. The real double-sided copper base PCB is the double-sided circuit layer designed by the customer with vias connecting the two-sided circuits.
The copper base PCB, circuit layer requires a large current carrying capacity, so a thicker copper foil should be used, with a thickness of generally 35μm~280μm; the thermal conductive insulation layer is the core technology of the copper substrate. The core thermal conductive component is composed of aluminum oxide and silicon powder and a polymer filled with epoxy resin. It has a small thermal resistance (0.15), excellent viscoelastic properties, and is resistant to thermal aging and can withstand mechanical and thermal stress.
The copper substrate metal base is the supporting component of the copper substrate. It is required to have high thermal conductivity. It is generally a copper plate. Copper plates can also be used (copper plates can provide better thermal conductivity). It is suitable for conventional mechanical processing such as drilling, punching and cutting.
The structure of the real and fake double-sided copper substrate can be divided into 5 layers: 1 layer is the top copper foil, 2 layers are thermal conductive insulation materials, 3 layers are aluminum plates, 4 layers are bottom insulation materials, and 5 layers are bottom copper foil. Their functions are as follows:
The 1st layer of copper foil is used as the top circuit pattern (conductive).
The 2nd insulating layer is also the key layer to reflect the thermal conductivity, also known as the thermal conductive layer, which plays a dual role of thermal conductivity and insulation. Whether the heat generated by the LED lamp can be quickly transferred to the aluminum plate, it is necessary to know the thermal resistance of the thermal conductive insulating material.
The function of the 3rd layer is to transfer the heat conducted by the thermal conductive insulating material to the lamp cup again. There is also an installation function.
The functions of the 4th and 5th layers are the same as those of the 2nd and 1st layers above.
Through the above structure, we can easily understand the thermal conductivity and heat dissipation principle of the copper base PCB. In addition, the special process of copper base PCB processing and the thermoelectric separation production technology have improved the thermal conductivity of the copper base PCB by several times. Therefore, most designers who make LED copper base PCB now design a thermoelectric separation thermal conductivity method to make the heat dissipation performance of the copper base PCB better.

Children, Play And The Environment
The future of the human race – our children – are the people who most need a safe and diverse environment of experience but are most at risk from it. Children are also at risk from the war, starvation and water-borne diseases crippling the Majority World. But not here? Blood tests reveal that nearly every person on Earth is harbouring detectable levels of dozens of persistent organic pollutants, including the worst: PCBs and dioxins. These chemicals cause liver damage and in the womb and in breast milk have measurable damaging effects on the brains of children. Currently, we are all involuntary subjects in a vast worldwide experiment on which each day we are exposed to hundreds of chemicals, many of which have been shown to cause harm, and many of which have never been tested. These toxins are endocrine disruptors that have major effects on reproductive health. The alarming decline in sperm counts is almost entirely restricted to the industrialised world. Reproductive defects in men have doubled. Female infertility and miscarriages are on the increase in the industrialised world and are directly linked to environmental causes, such as eating fish with high levels of industrial toxins – industrial New England is one infertility hot spot. They also damage the immune system and increase mortality rates from diseases we had thought treatable.
Children are uniquely vulnerable to environmental toxins. They have greater exposures to environmental toxins than adults. Pound for pound, children drink more, eat more and breathe more air than do adults due to their more rapid metabolism.
Children therefore have substantially heavier exposures to any toxins that are present in water, food, or air. Children taste everything and are much closer to the earth than we are, putting them at risk from toxins in dust, soil and carpets as well as toxins that from low-lying layers in the air, such as some pesticide vapours. Children undergo rapid growth and their development is uniquely at risk form toxins. The nervous system is not well able to repair any structural damage caused by environmental toxins: if cells in the developing brain are destroyed by chemicals such as lead, mercury, or solvents, or if vital connections between nerve cells fail to form, there is high risk that the resulting neurobehavioral dysfunction will be permanent and irreversible. Even if damage is not apparent, we are storing up disaster for the future. Many diseases that are triggered by toxins in the environment require decades to develop. Examples include mesothelioma caused by exposure to asbestos, leukaemia caused by benzene, breast cancer caused by DDT and some chronic neurological diseases such as Parkinson’s may be caused by exposure to environmental neurotoxins. Many of those diseases are more likely in later life if the toxin was ingested when young – cancers of all kinds, for instance.
The natural environment is important to children because it represents a place where they can interact with nature and play, relatively safely: away from traffic and also, temporarily, away from the control of adults. The primary place for play and socialising is ‘waste’ or rough ground, precisely because it is ignored by most adults. The value of such an environment is that, unlike an artificial one, such as concrete, tarmac or an artificial sports surface, children can interact with and change it. This happens in many ways, from obvious things like dens, tree houses and water play to more subtle things such as bike tracks which vary with the weather and which are constantly modified by the wear and tear resulting from the children’s use of them. The natural environment is constantly being polluted, threatened, damaged and destroyed; the ‘countryside’ is largely agribusiness farmland where children are denied access and at risk from the many pesticides, fertilisers and dangerous machinery most farmers use. In cities and towns, in addition to pollution, there is dumping – some of it toxic – and the constant threat of development of these ‘wasted’ (i.e. nonprofit making) brownfield sites for industry, roads and housing.
Tumblr media
Our response is not to stop using the 8000+ chemicals known to be damaging to our health – chemicals that capitalists swear are either not dangerous or necessary to our prosperity (sic, their profits!) – it is to increasingly restrict and protect our children from the environment: indoor play, antiseptic schools, air filters blowing during the school run every day, holidays abroad because we suppose the environment cleaner and safer. Children are told “don’t touch!”, “put it down”, “stay away”. They are forbidden to wander off, to explore and experience the world on their own terms because it has become so dangerous both in fact and in the minds of neurotic parents. We can do this because we have choices. But poor and marginalized people – and they exist in millions in the developed world as well – do not. They live by polluted rivers, must slog though toxic mud, drink pesticide-flavoured water, work in asbestos-ridden factories, labour in herbicide-drenched fields for the agricultural corporations. And often their children are beside them, if they are not already sick or dying. And why? Because children most of all have no power and no chance to escape the visible and invisible enemy – environmental pollution and degradation – that is damaging their health and development, stultifying their lives and prospects, and killing them slowly and eventually and all for money, and the pampered lives of the captains of industry, the corporate giants, the corrupted politicians.

Double Sided Flexible PCB
A flexible PCB is a kind of printed circuit board, also called a flexible printed circuit, or FPC for short. FPC is made of adhesive material or non-adhesive material. The copper used in the FPC production process is divided into electrolytic copper and rolled copper, and non-stick rolled copper is more flexible and foldable. A double-layer flexible PCB consists of two conductive layers with an insulating layer in between. It is an ideal product that requires circuit density. https://www.hitechpcba.com/flexible-pcb-manufacturing
