DELL Precision 7560 Palmrest Junction Board Ribbon Cable A20AL4

Genuine Dell OEM Palmrest Junction Board Ribbon

This genuine Dell OEM ribbon cable connects the palmrest junction board to the motherboard in the Precision 7560 laptop. It carries the Dell part number A20AL4 and alternate references GDB55_USH_FFC and NBX0002SC00. The part is supplied new and matches the component shown in the product imagery. It is intended for technicians or owners repairing the Precision 7560 chassis.

Signal Integrity Under Continuous Operation

The flexible flat cable maintains stable signal transmission between the palmrest junction board and the motherboard during sustained use. Its construction is rated for the thermal and mechanical environment inside the Precision 7560 without degradation over time. No active components or shielding are present that would alter behaviour under prolonged load. The cable simply passes the signals required by the junction board functions.

Straightforward Internal Installation

Installation requires opening the Precision 7560 chassis to access the palmrest junction board and motherboard connectors. The ribbon cable plugs directly into the ZIF sockets at each end with no soldering or firmware steps. Common issues arise when the connector latches are not fully seated or when the cable is creased during reassembly. Careful routing prevents pinching and ensures reliable contact.
