Technical Summary

UIF Mechanics

The module is made for 0.6 mm thick Printed Circuit Board. PCB has
four–layers. Reasons for that kind of material:
– Four layers are needed because of antenna is also assembled in this
module. Additional layers will improve shielding against RF–radiation.
– We do not need Flexible Printed Circuit (As used in HD841) because
we do not have side keys.
– PCB is easier to assembly than FPC.
– PCB is cheaper than FPC.
