I write about PCB design, PCB manufacturing, PCB assembly, and electronics manufacturing. My goal is to provide practical, easy-to-understand technical content that helps engineers, startups, and purchasing teams make informed manufacturing decisions. I cover topics such as PCB materials, layer stack-up, DFM, SMT assembly, testing, and production processes, with a focus on real-world applications and manufacturability.

Resistor Values for PCB Design: Tables and Selection Rules

Resistor Values for PCB Design Tables and Selection Rules

Resistor values affect current, voltage division, signal stability, heat, tolerance error, and long-term sourcing. A 10kΩ resistor may be a good GPIO pull-up, but the same value can be wrong for a precision ADC divider or a high-speed bus. Good resistor selection is not just a calculation. Before a value reaches the BOM, engineers should […]

1.2mm vs 1.6mm PCB Keyboard: Choose the Right Thickness

1.2mm vs 1.6mm PCB Keyboard

If you compare a 1.2mm vs 1.6mm PCB keyboard, the short answer is simple. Choose 1.2mm if you want more flex and a softer typing feel. Choose 1.6mm if you want stronger support, easier assembly, wider stabilizer support, and lower production risk. PCB thickness affects more than feel. It can change stabilizer fit, hotswap socket […]
