Testing a keyboard PCB is quite easy. The only real trick to testing a keyboard PCB is knowing how to easily test a keyboard PCB. There are a couple of ways to test a keyboard PCB. One of the best methods is to simply test the solder joints. If the solder joints are good, you can move onto the next step. If you see any problems with the solder joints, you’ll have to make sure that the board is working properly.
This is a step-by-step guide on how to easily test your PCB for functionality before you pour in hours of work into your project. It’s a simple process that can save you time and frustration. This guide will cover everything you need to know about testing your PCB.
Steps For How to Easily Test a Keyboard PCB
1. Clean Your Surface
You’ll want to ensure that the board is free of dust, debris, and other contaminants.
It is important that you keep your PCB clean so that you can easily read the markings on it.
You can also use a lint-free cloth to wipe down your PCB before you start working on it.
2. Connect Your PCB to PC
Connecting your PCB to your computer is easy. All you have to do is plug in the cable to your computer and the other end into your PCB. There are two types of cables: male and female.
A male to female cable is called a “male to male” cable, while a female to male cable is called a “female to female” cable.
If your PCB has an LED, you can plug it into the back of your computer.
You can see the LED glow when the computer is running.
The cable is usually blue and has a yellow stripe.
3. Open Your Switch Testing Software
The first thing you need to do is to open up your PCB in the Switch Hitter or VIA software. You should then open up the Test Matrix. The Test Matrix will show you what you need to test on your PCB. You should then set up the test, set the keyboard, and then start testing. When you test your keyboard, you should set the keys you want to test. You can set up the keys you want to test by using the Test Matrix. The Test Matrix will then show you which keys are connected to which wires.
4. Test Each Individual Switch
A quick test on each switch is very important. Before doing the assembly of the board, you should test each switch on the PCB. This way, you will be able to make sure that the switch is functional and that all the pins are properly connected. You should be able to see a light on the switch when you press it. If you find that the keypad is not working, you can use another switch or re-connect the switch. Make sure that you test the switches that are used for the backlight as well.
If it doesn’t work, it’s most likely that the key on the PCB isn’t working right. Continue down the rows and columns, testing each switch. You can see that there are many pads side by side for certain PCBs. It’s optional if it’s not a layout that you ever plan on using.

What is a Keyboard PCB?
A keyboard PCB is a printed circuit board (PCB) that has been designed to be placed inside a keyboard. It is usually the central component of a keyboard, and it connects all of the components together.
Through-Hole Printed Circuit Board (PCB)
Through-hole printed circuit board (PCB) is a method of manufacturing PCBs where through-holes are used instead of plated through-holes.
In the through-hole printed circuit board, the internal circuit is formed by using the through-holes, which are formed in a core material made from epoxy resin or polyimide. In general, the through-hole printed circuit board is manufactured by drilling a plurality of through-holes on a surface of the core material and then forming an inner conductor layer in each through-hole and forming an external conductor layer on the outer surface of the core material.
Standard Printed Circuit Board PCB
A standard printed circuit board (PCB) is a thin, flat sheet of insulating material with conductive traces on both sides.
PCBs are used to support and interconnect electronic components such as integrated circuits, resistors, capacitors, inductors, and other passive and active devices. One or more layers of copper foil are laminated onto a non-conducting substrate. A common method for producing a PCB is to first form multiple layers of alternating insulating and conductive material onto a continuous fiberglass sheet using an automated tape laminating machine. These sheets of material are then cut into discrete panels that are subsequently drilled with a series of through holes.
Hot-Swappable Printed Circuit Board (PCB)
Hot-swappable printed circuit board (PCB) is an electronic component that has a PCB and a set of electrical contacts that can be easily replaced in the field without having to dismantle the whole PCB.
The hot-swap feature allows easy installation, removal, and replacement of modules without causing damage to the circuit or affecting operation of the device. Hot-swap technology was originally developed for power supplies and power distribution systems. Power supplies are designed to supply a stable voltage and current to a load. In order to achieve this, a power supply contains circuits that regulate and convert electrical power from a source into the necessary levels of voltage and current. Power supplies are typically designed to operate over a wide range of conditions such as the supply voltages, temperatures, loads, and operating frequencies.
Tools:
- Metal Tweezers : A good pair of tweezers is essential. I suggest using a pair that has a very strong grip on your fingers so you can be confident you won’t lose them.
- PCB : You need a PCB to test a circuit board. However, you can make a simple PCB at home using a computer and a solderless breadboard.
- Compatible USB Cable :It is very important to make sure that your USB cable is compatible with your PCB. If it is not, then you may have a problem. This is because the USB ports on your PC are different than the USB ports on your PCB. You can check this by looking at your PCB’s specification sheet. If you can’t find the USB specification, you can call your PCB manufacturer to ask about it.
- Switch Testing Software : If your PCB is compatible, we prefer to use Switch Hitter. If you open it, you can use it many times on your computer. It is also a download program. Some PCBs are not compatible. You can check for compatible PCBs here. If it is, then you should download it. It’s easy to use and has a ton of features. A full list of recommended tools can be found here.

FAQ,S
How do I know if my PCB keyboard is damaged?
You can easily tell if your PCB keyboard is damaged if the keys don’t work when you press them. If they do, then you can safely assume that the keycap assembly and PCB are both intact.
How can I test my keyboard?
You can use a digital multimeter to measure the resistance between the white and black keys, or you can use a light bulb to test your keyboard. This will tell you if your key switches are working, and if the key caps and base are good.
Can you touch keyboard PCB?
It’s possible to touch the keyboard PCB, but you should know that you might ruin it. Most keyboards use a conductive material to connect the keys to the PCB, and that material can easily get damaged if touched. If you don’t know what you’re doing, it’s best to call an expert to handle the job.
Can you fix a short circuited keyboard?
Short-circuit keyboards usually happen due to a loose connection, or poor installation. A simple check of the connections, and replacement of the faulty key, should do the trick. However, if your keyboard is old or worn out, you might need a new keyboard to work again.
Conclusion
As soon as you receive your PCB, you should test it. Before you start building a keyboard, you want to make sure it’s done. If you forget to test it, be sure to solder it in. You will save time if there is trouble. It’s an easy process that can be done with little or no equipment. Good luck with building your first mechanical keyboard from this guide.
