Custom Keyboard PCBs: The Design and Factors Required



Are you a hardware enthusiast, gamer or engineer who wants to build a custom keyboard that meets your needs? You need comprehensive information on keyboard PCBs.

A keyboard PCB is what separates a regular keyboard from a mechanical keyboard. So whether the keyboard you plan to build is a mechanical keyboard or a traditional membrane keyboard, you'll need an in-depth look at the PCBs for different keyboard types.


Customizing a Mechanical Keyboard

First, the size of the keyboard you intend to build should determine the PCB size you choose. So, if you intend to build a large keyboard, choose a PCB board of 60 - 75%.

In contrast, smaller keyboards require a lower percentage, around 40 - 50. Therefore, it is best to choose a 75% PCB layout because it strikes a balance between functionality and size.

If you plan to create the board using ANSI, use the following stabilizers: Enter, Shift, Backspace, Spacebar.

However, if you want to use Numpad on your keyboard, choose a stabilizer with the following functions: + key, 0 key, Enter key.

For keyboard switches, we recommend that you choose PCB mounted buttons as they are typically more durable and softer to the touch than board mounts.

When it comes to keycaps, there are two main options to choose from; PBT and ABS plastic. Both keycaps are good. But PBT stands out because it is stronger than ABS plastic. The only hitch is that it is very expensive. But it's worth it.

Combining all the parts

First, you have to test the keyboard PCB to check if it works properly. You can do this by using a metal device to connect the switches of each contact pad.

Next, install the cherry stabilizer onto the PCB. Make sure the stabilizer is placed correctly. The general rule is to know the layout of your keyboard before installing the stabilizer.

Also, when installing the PCB mount switches, make sure to use the ideal holes for your keyboard layout. After mounting the switch to the PCB, flip the PCB over and solder the parts. You can solder the components by heating the electrical contacts and the pins of the switch evenly together.

However, please be careful not to turn the soldering into a dome. Instead, be patient and do not apply too much heat even if the solder is not flowing, as you may damage the components on the board.

Once the solder is done, the next step is to insert the keycaps. This process is the easiest thing you will ever do.

The last thing to do is to test your keyboard. Depending on the type of USB, Mini-USB, Micro USB or C type, that came with your PCB, you can plug it into your computer. Then, check all the keys and make sure they are working.

PCB Purchase Considerations  

PCB Layout

The PCB layout or size you choose when making a mechanical keyboard depends on the size of the keyboard you need. So, if you intend to use the keyboard for gaming and data entry, you will need a large size keyboard. If your keyboard is for gaming only, choose a regular size or a smaller size keyboard.

RGB Support

Choose a keyboard PCB with RGB or non-RGB backlight support. RGB backlighting is preferable because it creates a sort of bright atmosphere at night. And it's prettier. However, it is more expensive than the non-RGB backlit version.  

Brands

There are a large number of brands that produce keyboard PCBs on the market. However, not all of them offer high quality and reliable PCBs, so you have to be careful in choosing a company that produces quality PCBs. Fortunately, at TOPFAST, we believe in quality and show it off with our high quality keyboard PCBs.  

Price

When considering keyboard PCBs and other related components, it's important to pay attention to price. Therefore, we recommend that you place quality over price.
