Surface treatments for PCB circuit boards, such as tin spraying (HASL), OSP, and immersion gold (ENIG), protect the copper from oxidation, enhance solderability, and meet the evolving needs of modern electronics, but each has its own advantages, limitations, and environmental considerations.
This article discusses the design of an automated path detection system for measuring and recording the connectivity between component pins on a PCB, using a microcontroller-controlled front-end detection circuit, analog multiplexers, and voltage comparators to improve efficiency and accuracy in identifying pass/break relationships.
