    Abstract: A surface mountable power supply and a method of manufacturing the power supply. In one embodiment, the power supply includes: (1) a substrate having opposing upper and lower conductive layers (2) a lower electrical component having a first lead mounted on a first pad on the lower conductive layer and subject to forces capable of detaching the lower electrical component from the substrate when the power supply passes through a reflow soldering process, (3) an upper electrical component having a second lead mounted on a second pad on the upper conductive layer, (4) a solder located proximate the first lead, the lower electrical component of a sufficiently low weight such that a surface tension of a liquid state of the solder is sufficient to maintain the lower electrical component in contact with the lower conductive layer as the power supply passes through the reflow soldering process, (5) a planar magnetic device mounted on the substrate, the planar magnetic device having windings formed from a portion of conductive traces on the upper and lower conductive layers and a core disposed through apertures of the substrate and proximate the windings and (6) an inter-substrate conductive mount, coupled to the lower conductive layer, composed of a material having a melting point above a solder reflow temperature and adapted to mount the power supply to an adjacent substrate and provide a conductive path therebetween, the conductive mount including first and second compliant solder joints at interfaces of the substrate and the adjacent substrate, respectively.

    Abstract: A semiconductor chip module has semiconductor chips (12) each having contacts on its entire front face, and a multi-layered organic circuit board (15) having a small dielectric constant intermediate ceramic substrates (11) having the same thermal expansion coefficient as that of the semiconductor chip (12), each having contacts on its front and back faces corresponding to those of the semiconductor chip (12) and being electrically connected directly in a one to one relationship. The contacts on the semiconductor chip (12) and the corresponding contacts on the substrates (11) are connected by a solder, the contacts on the other of the substrate (11) and the corresponding contacts on the multi-layered ceramic circuit board (15) are connected by respective conductive pins (14) having a predetermined flexibility and rigidity through a predetermined gap therebetween. In this way there is the possibility of the relative displacement due to theremal expansion difference between the intermediate ceramic substrate (11) and the multi-layered organic circuit board (15).
