Interconnection Structure Of Interposer With Low CTE And Packaging Component Having The Same

摘要

Disclosed herein are printed circuit board assemblies made of a brittle material such as silicon, glass or ceramic and provided with a connector to electrically connect the same to an external connection member, and a method for molding the printed circuit board assembly wherein the printed circuit board assembly is molded by applying a polymer resin thereto to impart hardness to the printed circuit board assembly, and an electrode terminal to connect the same to the external connection member is exposed to the outside. Disclosed herein is also an interconnection structure of an interposer, the interconnection structure electrically connected to a main printed circuit board (PCB) through a solder joint is interposed between the interposer and the solder joint to prevent or reduce concentration of stress on the solder joint caused by differences in coefficients thermal expansion between the interposer and the main PCB.
