Patent ID: 7216424

Claim:
A method for fabricating electrical connections of a circuit board, comprising the steps of: providing a circuit board having a plurality of first and second electrical connection pads formed on a surface thereof, and applying a protective layer on the surface of the circuit board, the protective layer having a plurality of openings for exposing the first and second electrical connection pads; forming a conductive layer on the protective layer and the exposed electrical connection pads; applying a resist layer on the conductive layer, and forming a plurality of openings through the resist layer to expose a portion of the conductive layer corresponding in position to the first electrical connection pads; depositing a first metal layer in the openings of the resist layer; forming another plurality of openings through the resist layer to expose another portion of the conductive layer corresponding in position to the second electrical connection pads free of having the first metal layer thereabove; and depositing a second metal layer on the first metal layer deposited above the first electrical connection pads and on the exposed portion of the conductive layer corresponding in position to the second electrical connection pads.
