Patent ID: 7897199

Claim:
A method for plating an FPCB base board, comprising the steps of: providing an FPCB base board comprising a sprocket region; and placing an insulation shielding plate spatially opposite to the sprocket region of the FPCB base board to limit a thickness of a plating layer formed on the sprocket region of the FPCB base board; wherein a surface of the insulation shielding plate is an arc-shaped surface protruding from the insulation shielding plate to the sprocket region, whereby a distance between the surface of the insulation shielding plate and the sprocket region gradually reduces from two ends of the surface of the insulation shielding plate to a center/middle portion of the sprocket region along a width direction of the sprocket region, and a distance between the surface of an insulation shielding plate and a surface of the sprocket region is in a range from about 1 millimeter to about 50 millimeters; and plating the FPCB base board.
