Abstract

A method of fabricating an electrical connecting structure of a circuit board is disclosed. The method includes: providing a circuit board having a plurality of first and a plurality of second conductive pads; forming on the circuit board a solder mask having a plurality of openings to thereby expose the first and the second conductive pads; forming an metal adhesive layer on the first and the second conductive pads; forming a conductive layer on the circuit board and the metal adhesive layer; forming on the conductive layer a resistive layer, wherein a plurality of openings are formed in the resistive layer to expose the conductive layer on the second conductive pads; forming a metal post by electroplating through the conductive layer on the second conductive pads; removing the resistive layer and the conductive layer covered underneath; and forming a soldering layer on the metal post.
