Copper Alloys for FPC Connectors
Backgrounds and Trends
Flexible printed circuit (FPC) connectors are used to connect FPCs to boards such as those for LCD backlights inside smartphones and tablets, and touch panels. Connectors are increasingly trending toward lower profile and narrower pitch as devices become more compact, requiring improvement in connection reliability and measures to deal with increased current flow.
