  • Patent number: 7615873
    Abstract: A substrate, which has semiconductor die arranged thereon, uses at least one solder flow stop, closely surrounding at least a portion of at least one mounting pad on which the die are mounted, to prevent die rotation during solder reflow. The at least one solder stop is non-wetting, during a solder reflow process, to solder used to mount the die.

  • Publication number: 20030107120
    Abstract: A power module having a lead frame with a plurality of power switching devices and a plurality of driving devices mounted thereon. The driving devices control the power switching devices to provide power to a plurality of output leads via first wire bonds. The first wire bonds are substantially parallel to each other between the power switching devices and the output leads. Each power switching device preferably includes a power semiconductor device and a diode, the diodes and power switching devices being interconnected by second wire bonds which are also substantially parallel to each other. The power switching devices preferably comprise bare semiconductor die mounted on the lead frame, the lead frame and power switching devices being enclosed in a molded package. The molded package are preferably formed by transfer-molding or injection-molding.

  • Patent number: 6255722
    Abstract: A semiconductor device package is provided which can accommodate currents larger than those of similarly sized standard device packages such as the “TO-247” package. Higher currents are accommodated by allowing a larger semiconductor die to be mounted on the device's lead frame than can be mounted on a similarly sized standard package. An improved mold clamping area is also provided which reduces the area from which damaging moisture can enter the molded package and increases the distance required for moisture to contact the die. Clip arrangements are also provided to mount the device package to a circuit board or heat sink, thereby allowing the increased operating temperatures associated with the increased operating currents to be efficiently dissipated.

  • Patent number: 5902959
    Abstract: A surface mount semiconductor package includes a semiconductor device, a metal pad on which the semiconductor device is mounted, and a housing formed of a flowable material which bonds to the metal pad and encapsulates the semiconductor device when cured, where the metal pad includes a waffled surface opposite the surface on which the semiconductor device is mounted for accepting solder between the metal pad and a substrate and for permitting solder wetting therebetween.
