FLEXIBLE PRINT CIRCUIT BOARD AND EMBEDED ANTENNA FOR MOBILE COMMUNICATION DEVICE

摘要

Disclosed is a printed circuit board with an elastic electrical contact terminal and a contact part which is electrically connected to the electrical contact terminal using the elasticity of the elastic electrical contact terminal and exposed to the outside. A flexible printed circuit board comprises a base sheet made of a polymer material; a conductive pattern on the top of the base sheet; a polymer based cover sheet or polymer coating layer which adheres to the top of the conductive pattern and the base sheet, and has an opening on a portion of the conductive pattern forming the contact part; a metal plating layer in the opening on the conductive pattern; and an anti-corrosive layer on the metal plating layer. The surface of the anti-corrosive layer is at the same height as or higher than the surface of the polymer coating layer or the cover sheet as the thickness of the metal plating layer is adjusted.
