Whether you're a gamer, coder, writer, or design enthusiast, creating your own keyboard can be both a fun and functional project.
Building a custom mechanical keyboard is more than just assembling parts—it's about crafting a personalized typing experience that suits your preferences for sound, feel, and layout. Whether you're a gamer, coder, writer, or design enthusiast, creating your own keyboard can be both a fun and functional project. Here's a comprehensive guide to get you started.
Essential Components and Tools
Before diving into the build, gather the necessary components and tools:
Core Components:
Keyboard Case: The outer shell that houses everything.
PCB (Printed Circuit Board): The mainboard that handles all keystroke inputs.
Switch Mounting Plate: Adds structural stability and aligns switches.
Mechanical Switches: Choose based on feel (linear, tactile, clicky) and sound.
Stabilizers: Used for larger keys like Spacebar, Enter, Shift, and Backspace.
Keycaps: The visible top parts of keys, available in various profiles and materials.
USB Cable: Typically detachable and USB-C for modern builds.
Tools You’ll Need:
Screwdriver (often Phillips head)
Soldering iron and solder (unless using a hot-swap PCB)
Tweezers or a metal bridge tool
Keycap and switch pullers
Lubing tools and lubricant (optional)
Damping materials like foam or neoprene (optional)
Step-by-Step Assembly Guide
1. Plan Your Layout
Choose a layout based on your needs and desk space:
60%: No function row, arrows, or numpad.
65%: Adds arrow keys.
75%: Includes function row.
Tenkeyless (TKL): Lacks numpad but retains all other keys.
Full-size: Includes everything.
Your chosen layout determines the type of PCB, case, and keycaps you’ll need.
2. Test the PCB
Before assembly, test your PCB to ensure it works:
Connect the PCB to your computer.
Use tweezers or a metal bridge to simulate switch presses across all keys.
Use an online keyboard tester to confirm input registration.
3. Prepare and Install Stabilizers
Stabilizers ensure a smooth press on larger keys. To prepare:
Assemble the stabilizers as per manufacturer instructions.
Apply lubricant to the stabilizer inserts and housings.
Snap or screw them into the designated slots on the PCB.
4. Mount the Plate and Insert Switches
Align the plate over the PCB.
Insert switches through the plate holes into the PCB.
Ensure all switch pins are straight and fully inserted.
If using a hot-swap PCB, switches will click into place. If not, continue with soldering.
5. Solder the Switches (If Required)
If your PCB isn’t hot-swappable:
Heat your soldering iron to the recommended temperature (around 350–400°C).
Carefully solder each switch pin to its respective contact on the PCB.
Double-check that each joint is clean and secure.
6. Add Damping Material (Optional)
To improve acoustics:
Cut foam or neoprene to fit between the PCB and case.
Place it inside the bottom of the case to reduce vibration and mute keystroke noise.
7. Assemble the Case
Place the assembled PCB, plate, and switches into the keyboard case.
Secure the build using the provided screws or case fasteners.
8. Install Keycaps
Align each keycap with the switch stem and press down firmly.
Start with larger keys and work your way to the smaller ones for better alignment.
9. Configure Keyboard Firmware
If your board supports QMK or VIA firmware:
Download the relevant configuration tool.
Remap keys, set up macros, or configure RGB lighting profiles.
Save and flash the firmware to the PCB.
Tips for a Better Build
Use a starter kit: Great for beginners since all components are guaranteed to be compatible.
Lube your switches: This greatly enhances smoothness and reduces scratchiness.
Research keycap profiles: Sculpted profiles like SA or Cherry feel different from flat ones like DSA.
Mind your soldering: Avoid cold joints or excess solder to maintain a clean build.
Document your build: This helps if you ever troubleshoot or upgrade parts in the future.
Final Thoughts
A custom mechanical keyboard isn’t just a peripheral—it’s a personal statement. From the tactile feedback of your chosen switches to the unique aesthetic of your keycaps and case, every detail is in your hands. Take your time, enjoy the process, and in the end, you'll have a typing tool that's as unique as your workflow.
