Mechanical keyboards are incredibly versatile and customizable. If you are a beginner in mechanical keyboard customization, you might be overwhelmed by the numerous options and processes involved. But do not worry, we’re here to guide you by providing thorough insights into the customization process.

## WHAT MAKES MECHANICAL KEYBOARDS CUSTOMIZABLE?

Mechanical keyboards feature unique layers: the PCB (printed circuit board), the housing, the keycaps, and the switches. Each part can be customized according to your choice, style, and usage. Let’s examine each component more closely:

### The PCB

The PCB is the keyboard’s brain. Every keyboard press is detected by the PCB, which then sends a signal to the computer. PCBs can come pre-programmed, semi-programmable, or wholly programmable. Fully programmable PCBs let you tailor your keyboard experience, mapping any key to any function, enabling macros, or even managing the keyboard’s lighting.

### The Housing

The housing, also called the case or frame, holds the PCB and the switches. Housings mainly come in ABS, polycarbonate, or aluminum. However, some custom boards allow for even more exotic build materials like acrylic, brass, or carbon fiber.

### Switches

The heart of a mechanical keyboard is the switch. Every key press results in a switch activation. There are several types of mechanical switches, each offering a different feel and sound. Linear switches like Cherry MX Reds provide a smooth keystroke. Tactile switches, like Cherry MX Browns, includes a bump midway pressed for feedback. Clicky switches, like Cherry MX Blues, provide feedback and an additional click sound.

### Keycaps

Keycaps make the most immediate visual impact on a keyboard. They’re often made from ABS or PBT plastic, with PBT being more resistant to shine. Keycaps can be dye-sublimation, double-shot, or laser-etched – referring to the method of creating legends.

## STEP-BY-STEP GUIDE TO CUSTOMizing YOUR KEYBOARD

### Step 1: Choose Your Layout

Consider which keyboard layout best suits your needs: full size (standard layout), tenkeyless (missing the number pad), or compact layouts like 60%, 65%, and 75%. Experiment with different layouts and decide which works best for you.

### Step 2: Choose Your Parts

Depending on your chosen layout, pick a PCB that’s compatible with the size. For the case, you’ll select a material that matches your aesthetic and sound preferences. In switches, you’ll decide between linear, tactile, or clicky, or perhaps a combination. And finally, keycaps should round off your setup.

### Step 3: Assemble Your Keyboard

Once all parts arrive, it’s time to assemble. If you’ve opted for a hot-swappable PCB, no soldering is required, making it more beginner-friendly. Simply insert the switches into the PCB, and once they’re in place, settle the PCB inside the case. Next, attach the keycaps onto the switches.

### Step 4: Program Your Keyboard

Should you select a programmable PCB, you would be able to map keys according to your convenience. Software like QMK Firmware allows full customization of your keys.

## BUILD PARTS

### Hot-Swappable PCB and Plate

As a beginner, start with hot-swappable PCBs and plates. Here, switches can be swapped without soldering.

### Semi or Fully Programmable PCB

Programmable PCBs allow for macros and custom key mapping. Depending on how much control you want over your keyboard, you can opt between semi or fully programmable PCBs.

### Stabilizers

Stabilizers are essential for larger keys, ensuring they don’t wobble and providing a smooth keystroke.

### Case & Keycaps

For cases, weigh in materials like aluminum, acrylic, and polycarbonate. Finally, pick out attractive keycaps to complete your setup.

## IMPROVING THE ACOUSTICS OF YOUR KEYBOARD

The sound of a keyboard can significantly impact the overall typing experience. Here are ways to modify this:

### Lube Your Switches and Stabilizers

Lubbing switches and stabilizers reduces friction, leading to a smoother keystroke and more pleasing sound. Usually, thin lube is used for tactile and clicky switches, and thicker lube for linear switches.

### Install Sound Dampening Materials

Sound dampening materials, like foam or silicone, can reduce echo inside the case, delivering a deeper low-pitched sound.

By seeing through this guide, you have started your journey into mechanical keyboard customization. Each step is fun and rewarding, and you have an extensive range of options and combinations to choose from, individually suiting your style and purpose. Merely consider the factors and elements that interest you, and start building!
