Peek for Lead-Free Soldering Processes and Electronics Applications

摘要

The electronics industry is moving from lead-based solder systems to lead-free solder systems. This change increases the processing temperatures used to melt and flow the new lead-free solders. This is causing many of the traditional polymeric materials used for electronic components to fail. Therefore, the polymers with high temperature resistance, such as VICTREX?? PEEK (poly (aryl ether ether ketone)) polymer, are getting very important in the manufacturing processes using lead-free solders. In this paper, the performance of PEEK polymer and other plastic materials are presented from a lead-free soldering process viewpoint. This paper also describes some applications in which PEEK polymer has been successfully applied, including mobile phone secondary battery gaskets, speaker diaphragms, connectors, and so on.
