In the sophisticated world of electronics manufacturing, cleanliness is not just a aesthetic requirement; it is a critical factor influencing reliability, longevity, and performance. As components become smaller and circuit densities increase, the potential for contaminants to cause catastrophic failures—such as leakage currents, corrosion, or electrochemical migration—grows significantly.
The guidelines also touch upon methods for verifying that the cleaning was successful: ipc-ch-65 pdf
