5.4 ZIF connector
This chapter provides specifications and handling instructions for the 40-pin ZIF connector
and the Flat Flexible Cable (FFC) used to connect the GSM engine to the host application.
The ZIF (zero insertion force) design allows to easily fasten or remove the cable without the
need for special tools. Simply insert the FFC cable into the open socket without using any
pressure. Then carefully close the socket lid until the contacts of the socket grip the cable
contacts.
