FLEXIBLE PRINTED CIRCUIT (FPC) BOARD

摘要

A flexible printed circuit (FPC) board having reinforcing pattern against bending is disclosed. The FPC board provides an RF interconnection extending from an RF electrode. Two ground electrodes are formed in respective sides of the RF electrode. The ground electrodes extend respective extended portions along the RF interconnection to protect the RF interconnection from breakage due to bending of the FPC board. The extended portion provides an end portion bent toward the RF interconnection to compensate for impedance mismatching of the RF interconnection.

主权项

1. A flexible printed circuit (FPC) board soldered to a rigid circuit board, comprising:
a top electrode provided in a top surface of one end of the FPC board; and a back electrode provided in a back surface of the one end of the FPC board, the back electrode being connected to the top electrode through a via hole and soldered to a pad provided in the rigid circuit board, wherein at least one of the top electrode and the back electrode extends an interconnection and another of the top electrode and the back electrode extends an extended portion terminated in the one end of the FPC board.
