A low profile integrated module is fabricated to include sheets of material, such as ceramic or PCB, fixed together and including a via extending through at least one of the plurality of sheets from the lower module surface partially to the upper module surface and in a side module surface. The via is filled with conductive material. The module is then mounted on a supporting substrate having a solder pad on the mounting surface with an area greater than the lower surface of the via. The lower surface of the via is positioned adjacent the upper surface of the mounting pad and soldered so that solder wicks up the via along the side module surface.

Low profile integrated module interconnects and method of fabrication

Low profile interconnect structure includes an electronic circuit module with a plurality of mounting areas and a plurality of electrical contact areas defined by the mounting surface. The plurality of mounting areas are spaced a first distance from a mounting and interconnect surface parallel to and spaced from the mounting surface and the plurality of electrical contact areas are spaced a second distance, less than the first distance, from the mounting and interconnect surface. Large solder balls are used between the mounting areas and the mounting and interconnect surface to form a solid mount and smaller solder members are used for electrical interconnections.
