Understanding the Aesthetics and Engineering Behind the Blue Circuit Board     The Blue Circuit Board is not merely a product of visual preference—it is a combination of chemistry, light physics, and material science. At its core, a blue PCB is identical in electrical structure to other boards: it consists of copper traces laminated between dielectric layers, all protected by a solder mask. Howeve...

From ENIG to Hard Gold: Selecting the Right PCB Plating Process for Your Performance Needs 1. Definition and Fundamentals of the PCB Plating Process 1.1 What Is a PCB Plating Process    The PCB Plating Process is the controlled deposition of metallic layers on the surface or through the holes of a printed circuit board. This process creates conductive paths, enhances solderability, and protects co...

Achieving Gold Standard Yields: Critical Fabrication Notes for the ENIG PCB Process 1: Understanding the ENIG PCB Process – Definition and Technical Framework The Origin and Evolution of the ENIG PCB Process    The ENIG PCB Process was developed in response to the limitations of traditional solder-leveling and organic surface protection techniques. Before ENIG gained widespread adoption, Hot Air S...
