High-frequency electronic package with arbitrarily-shaped interconnects and integral shielding

摘要

A surface mountable high frequency electronic package consisting of substrates stacked on top of each other, with arbitrarily-shaped solder structures such as balls and walls connecting them together; forming a fully-shielded, environmentally-sealed, sandwich in which smaller electronic components and devices are placed. In addition to providing electronic and mechanical interconnection to a mother substrate, the solder structures also provide electromagnetic isolation and shielding, controlled-impedance transmission line structures, and an environmental seal. The entire package is fabricated from conventional materials and components assembled together with automated processes.
