2.4.2 Removing RF and Logic Boards From Chassis
5
Separate the front cover and chassis as described in the preceding section. The RF and
logic boards are located inside the metal chassis as shown below.
6
Remove the shields over the RF and logic boards. These shields insert in slots on one
side of the chassis and then clip to the other side of the chassis. These shields also hold
the boards in place.
7
Unplug the antenna cable from the RF board using a plier or similar tool at the location
shown below. Unlock the logic board flex circuit by sliding the tab on the connector
outward. The RF and logic boards can now be removed.
8
When handling these boards, minimize bending of the flex circuit to prevent it from
being damaged. Before replacing the RF board, make sure there is adequate heat sink
compound on the pad under the RF module.
