  • Patent number: 7852635
    Abstract: The present invention provides a PWB for attaching electrical components thereto. One aspect of the PWB includes multiple PWB insulating layers having conductive traces therebetween. The PWB has an interconnect opening located in the multiple PWB insulating layers that intersect at least a portion of the conductive traces. The interconnect opening has ledges therein, wherein each of the ledges separates a first group of the conductive traces from a second group of the conductive traces. The present invention also provides a method of making the PWB and also provides a power converter implementing the edge plate interconnects.

  • Patent number: 7304862
    Abstract: The present invention provides a PWB for attaching electrical components thereto. The PWB includes a stack of insulating layers, conductive layers located between the insulating layers, wherein the conductive layers terminate at an edge of the PWB, and an edge plate interconnect located on the edge. The edge plate interconnect is free of a complementary via and contacts and electrically interconnects the conductive layers. The present invention also provides a method of making the PWB and also provides a power converter implementing the edge plate interconnects.

  • Patent number: 6310301
    Abstract: An inter-substrate conductive mount for a surface mountable circuit board, a method of manufacturing the circuit board and a surface mountable power magnetic device. In one embodiment, the circuit board includes: (1) a substrate, (2) an inter-substrate conductive mount composed of a material having a melting point above a solder reflow temperature and including a compliant solder joint at an interface of the substrate and (3) a solder located proximate the conductive mount, the conductive mount of a sufficiently low weight such that a surface tension of a liquid state of the solder is sufficient to maintain the conductive mount in contact with the substrate as the solder is brought to the reflow temperature, the conductive mount being capable of mounting the substrate to an adjacent substrate and providing a conductive path therebetween.
