ENHANCED CHIP BOARD PACKAGE STRUCTURE

摘要

An enhanced chip board package structure includes a chip board and a plurality of enhanced structures, which are formed in the blind openings of the non-effective region of the chip board. Each enhanced structure has an opening. The mechanical strength is reinforced by the enhanced structures without changing the whole thickness so as to overcome the problem of warping. Meanwhile, the three-dimensional stability is thus enhanced. The opening of the enhanced structure can be selectively filled with the filler such that the mechanical strength is further reinforced and the thermally conductive effect is greatly improved.
