Abstract
The structure of a solder mask for the circuit module of a BGA substrate mainly comprises a power ring, a ground ring, a plurality of holes, a plurality of first holes and a plurality of second holes. The power ring and the ground ring are arranged between the chip area and the wire bonding area; the first openings are arranged on the power ring and the ground ring for receiving the electronic part. Thus the substrate meets the requirement of keeping the electronic part close to the chip. The second openings are arranged over the associated holes which electrically connect to the power ring and the ground ring by traces; these holes do need not to electrically connect the power layer and the ground layer of the substrate. The openings of the present invention use the power ring, ground ring and the holes of the substrate to electrically connect to the electronic parts, so that the present invention does not need to provide other holes or traces thus simplifying the structure of the substrate. The distance of two openings of the present invention can, moreover, be adjusted according to the length of the electronic part.
