The interposer with patch-panel allows you to connect your dock to your device via flat-flex cables (FFC) or other connectors. The patch-panel allows you to reconfigure the wiring between the driver and your device. For example, if only certain device pins are wire-bonded, you can connect to those instead of those that are not wire-bonded. It also provides mechanical stability as it gives an anchoring point for the various cables – if a cable is pulled out from the dock, it will not affect the device.
It is not necessary to purchase an interposer from us. Because you may know how you want to connect your dock to your device, you may be able to do it yourself or find a way that works better for your system.
