  • Method of fabricating gold finger of circuit board
    Patent number: 8141242
    Abstract: A method for fabricating a gold finger of a circuit board is provided. First, a circuit board having a board edge for cutting is provided. Next, a copper conducting wire pattern is formed on the circuit board. The copper conducting wire pattern includes a plurality of gold finger bodies and a plurality of tie bars. Each tie bar is connected to a corresponding gold finger body, and the tie bars are disposed across the board edge. Thereafter, a surface of each gold finger body is plated with gold, and the tie bars on the board edge are removed by etching. Because the tie bars on the board edge are removed, tear resistance of the gold finger is maintained after cutting the board edge.
