Ultra-clean IoT PCBs assure high reliability
IoT devices going into military/aerospace, medical and/or highly specialized industrial applications demand ultra-high reliability so they operate properly according to their tight specifications. That means the small IoT printed circuit boards (PCBs) must be ultra-clean and virtually free of any contaminants or chemical residues.
The Internet of Things (IoT) world may be exciting, but there are serious technical challenges that need to be addressed, especially by developers. In this handbook, learn how to meet the security, analytics, and testing requirements for IoT applications.
But to understand how best to gain that IoT reliability, we first have to check out PCB surface finishes or coatings, because therein can lie tiny and miniscule residue that sabotage that reliability. Regardless of size, whether large or small, like IoT PCBs, all printed circuit boards have these surface finishes. The purpose of these finishes or coatings is not only to protect the board’s copper finish, but also to keep the copper from oxidation and deterioration. Read more…
