Hård guldbelægning: Design af kantstik og kontaktflader til ekstrem slidstyrke
Introduction to Hard Gold Plating in PCB Design When designing printed circuit boards (PCBs) for high-reliability applications, surface finish selection is one of the most critical decisions an engineer must make. While Electroless Nickel Immersion Gold (ENIG) provides an excellent coplanar surface for soldering surface-mount components, it is fundamentally unsuitable for sliding contact applications. For […]
