Abstract

The invention relates to a ball grid array packaging structure and a packaging method thereof. The packaging structure comprises a circuit board provided with an upper surface and a lower surface. The method comprises the following steps that: firstly, the upper surface is provided with patterned conductive contacts, while the lower surface is provided with corresponding metal endpoints which are electrically connected with the patterned conductive contacts; secondly, a plurality of welding pads on the active surface of a semiconductor chip are electrically connected with the patterned conductive contacts; thirdly, a packaging body is used for coating the semiconductor and the upper surface of the circuit board; and finally, a plurality of conducting elements are electrically connected with the metal endpoints on the lower surface of the circuit board.

Description

technical field [0001] The invention mainly discloses a semiconductor package structure, more particularly a package structure and method for electrically connecting a semiconductor chip with a conductive contact on a carrier to form a ball grid array. Background technique [0002] In recent years, with the continuous maturity and development of semiconductor technology, various high-performance electronic products are constantly being introduced, and the functions of electronic products are developing towards humanization and multi-function. However, there are various functions inside electronic products. integrated circuit (IC) components. In the production process of electronic components, integrated circuit packaging plays a very important role, and integrated circuit packaging can be roughly divided into dual in-line package (DualIn-line Package, DIP), ball grid array package (Ball Grid Array) package, BGA) and tape automatic bonding (Tape Automatic Bonding, TAB) packa...
