CIRCUIT CARD ASSEMBLIES HAVING CONNECTOR-LESS PERPENDICULAR CARD-TO-CARD INTERCONNECTS

摘要

A coupled circuit card assemblies (CCCA) includes a first CCA (CCA1) having at least one board receiving side aperture including electrical conductor lined through-holes above and/or below the aperture. A second CCA (CCA2) has surface electrical conductors proximate to one of its edges (“connectable edge”). The connectable edge of CCA2 penetrates into the board receiving side aperture of CCA1 to provide a perpendicular attachment including a plurality of reinforced joints including a low temperature flowable material that electrically connects respective surface conductors on at least one of the top side and bottom sides of CCA2 to respective electrical conductor lined through-holes on CCA1. The low temperature flowable material can be solder.
