Keyboard PCB board, also known as a printed circuit board, is one of the core components of a keyboard, responsible for connecting individual keys and transmitting electrical signals.
Determining the Design Approach
Selecting an Open-Source Solution: Numerous open-source projects offer various keyboard PCB design solutions. By downloading open-source files, you can obtain PCB schematics and related documentation for different designs.
Software Selection: Choose suitable design software such as KiCad, Altium Designer, etc.
Drawing Schematics
Select Components: Search for required components within the software—such as switches, diodes, controllers—and place them on the schematic.
Connect Components: Wire components according to circuit design principles, ensuring accurate definition of network ports and pin numbers.
Designing PCB Layout
Import Positioning Board CAD: Import the keyboard positioning board CAD file as needed to precisely place switches and other components.
Routing and Component Placement: Perform automatic or manual routing, then strategically position other components like header pins and LED locations based on layout requirements.
Generate Gerber Files
Export Production Files: Upon design completion, export Gerber files from the design software—the format manufacturers require for PCB production.
Additionally, when further exploring keyboard PCB board customization, consider these aspects:
Hot-swappable vs. non-hot-swappable switches: Hot-swappable switches allow replacement without soldering, ideal for users who enjoy experimenting with different tactile sensations.
Monochrome LEDs or RGB LEDs: Choose between single-color backlighting or color-changing RGB backlighting based on personal preference.
Firmware programming: For advanced customization, learn to program QMK firmware to enable full key remapping and complex macro commands.
Custom keyboard PCB board assembly is an activity that comprehensively tests design skills, circuit knowledge, and soldering techniques. It not only delivers a professional-grade keyboard experience but also fulfills your personalized needs and creative expression. During the customization process, focus on design details and precision while also considering comfort and functionality in actual use.
