ABSTRACT:
Provided is a circuit board including: a circuit board body with at least one surface having a plurality of electrically connecting pads; an insulating protection layer formed on the circuit board body and formed with an opening corresponding in position to one of the electrically connecting pads, being larger than the electrically connecting pad, and not being in contact with the periphery of the electrically connecting pad; and a soldering material formed on, and confined to, the electrically connecting pad; thus allowing an electrically conductive element limited in the opening formed in the insulating protection layer to be fabricated from the soldering material by a reflow process with a view to forming a fine-pitch electrically connecting structure.
