Abstract:
1. A golden finger for flexible printed circuitboard (FPC), being a stacking structure composed of a bottom substrate, a bottom copper layer, a cover layer, and a top copper layer by arranging those from bottom to top in a stacking manner, comprising: at least one first routing, formed on the bottom copper layer; at least one second routing, formed on the bottom copper layer; at least one first pin, formed on the top copper layer and arranged in a first line; at least one second pin, formed on the top copper layer and arranged in a second line; at least one first via hole, each being disposed at a position between its corresponding first pin and first routing while having a conductive material disposed therein for enabling the first pin to connected with the first routing electrically; and at least one second via hole, each being disposed at a position between its corresponding second pin and second routing while having another conductive material disposed therein for enabling the second pin to connected with the second routing electrically, wherein the at least one first pin and the at least one second pin are arranged in a staggered conformation as each first pin in the first line is not aligned exactly with one second pin selected from the at least one second pin in the second line.
