Abstract

The present invention relates to a semiconductor chip assembly which includes a semiconductor chip that includes a conductive pad, a conductive trace that includes a routing line, a metal containment wall and a solder terminal, and a connection joint that electrically connects the routing line and the pad. The metal containment wall includes a cavity, and the solder terminal contacts the metal containment wall in the cavity and is spaced from the routing line.

Description

technical field [0001] The invention relates to a semiconductor chip package structure, especially a semiconductor chip package structure with a metal wall at the soldering end, and a manufacturing method of the semiconductor chip package structure. Background technique [0002] Currently, semiconductor chips have input / output pads, which must be connected to external circuits so that they can realize part of the functions of the electronic system. The connection medium is mainly a metal wire array (such as a lead frame) or a support circuit (such as a substrate), although the connection medium can be directly connected to the circuit operation panel (such as a motherboard). Currently, many connection technologies are widely used, including wire bonding, tape automated bonding (TAB) and flip-chip bonding. [0003] During the next level of assembly, the semiconductor chip package structure is connected to other circuitry such as a printed circuit board (PCB) or motherboard. ...
