Abstract
A substrate structure is provided, which includes: a substrate body having a plurality of conductive pads; an insulating layer formed on the substrate body and having a plurality of openings for correspondingly exposing the conductive pads; and a plurality of ring bodies formed in the openings and corresponding in position to edges of the conductive pads. As such, a plurality of conductive elements can be subsequently formed inside the ring bodies so as to be prevented by the ring bodies from expanding outward during a reflow process, thereby protecting the insulating layer from being compressed by the conductive elements and preventing cracking of the insulating layer.
