Problem

Service is aware of an issue, identified in factory testing and highlighted by the
field, on the GSM V220. Some units, returned with various customer complaints
including “Turn On/Off – No Turn On” and “Display Main – No Display”, were
found to be caused by poor connection between the flex cable and the PCBA at
the J932 40-pin connector. In some instances it was found that the flex cable is
making contact with the edge of the base front housing. See Fig. 1.0 below. This
prevents the connector from being fully seated and will result in intermittent
failure after drop.

The root cause of the issue has been determined to be a connector shift, due to
surface pulling tension, during pick & place – SMT process. If connector is shifted
in the wrong direction edge of flex can contact housing. See Fig. 2.0 below.
