What are the advantages of COF?
PenMount provides custom COF design. COF (Chip on Flex) refers to soldering the PCAP touch controller directly to the FPC tail.
By integrating the controller IC into the touch panel, less space is required in the mechanism design. The FPC can be designed to various lengths, widths, and curvatures to facilitate assembly in small product. COF does not require touch panel end connectors and cables.
