UIF Flexes
There is two flexes that are connected to the UIF module and go through
the hinge. The other one is 33–pin flex. It has all active signals for the UIF
module and three ground pins. It is connected to the 33–pin flex
connector. The other one has one wide ground line. It is connected by
using two sided copper tape with conducting adhesive. It is needed to
improve EMC characteristics.
