摘要

Statements on the continuous temperature resistance of both conformal coatings and solder masks are becoming increasingly important. On the one hand, the ambient temperatures in which electronic assemblies are operated are getting higher, and on the other hand, the ever-tighter population density means the share in the temperature load caused by inherent heat is growing markedly. The continuous temperature resistance of electrical insulating materials can be judged by an examination according to EN 60216. Depending on the type of polymer, conformal coatings based on organic polymers can be used up to 150℃ permanent load and/or 165℃ short-term load. Only above these temperatures silicone lacquers or polyimides are mandatory.
