What Are Mechanical Keyboard PCBs?

Explore the core workings of mechanical keyboard PCBs! In this guide, we’ll unveil the mysteries behind these crucial components and how they support your keyboard layout.

How PCBs Work

In a mechanical keyboard, the PCB (Printed Circuit Board) functions as the "brain" of the entire setup. It transmits your keystroke signals to the computer, ensuring that each press registers accurately. If the PCB malfunctions, the keyboard won’t work correctly. That’s why testing the PCB before assembling your keyboard is essential. We’ve prepared a guide on how to test your PCB to make this easier for you.

What Other Features Do Mechanical Keyboard PCBs Offer?

Some mechanical keyboard PCBs allow for screw-in or clip-in stabilizers, which offer a more stable experience than plate-mounted stabilizers, especially for larger keys like the spacebar and enter key. Certain PCBs are also equipped with hot-swap sockets, letting you replace switches without soldering. Additionally, you can choose a PCB with built-in RGB lighting, or add RGB features to boost the keyboard’s visual appeal.

How Do You Mount a Keyboard PCB?

There are several ways to mount your keyboard’s PCB, and here’s a quick overview of some common methods. A top mount setup secures the PCB to the top of the keyboard case, while tray-mounting fastens it to the bottom. However, tray-mounting can create extra tension in certain areas, which may impact typing feel. Another popular option is gasket mounting, which involves placing foam pieces between the PCB and the plate for a more cushioned typing experience.

What Layouts Do Mechanical Keyboard PCBs Support?

Mechanical keyboard PCBs can support almost any layout, such as 60%, 65%, 75%, TKL (tenkeyless), and full-size 100% keyboards. If you’re interested in custom designs, various platforms like AllPCBs and PCBway offer DIY options, allowing you to create unique layouts and designs.

The PCB is undoubtedly the most essential component in building a mechanical keyboard. Understanding how it works and checking its condition can lay the foundation for creating a perfect keyboard setup.
