Abstract: A leadless plastic chip carrier is constructed by half etching one or both sides of the package design onto a leadframe strip so as to create unique design features such as power and/or ground ring surrounding the die attach pad, interlocking rivet head construction for the contact pads, and an interlocking pattern for the die attach pad. After wire bonding and molding, a further etching is performed to isolate and expose contact pads. Singulation of individual chip packages from the leadframe strip is then performed by saw singulation or die punching.

Abstract: A power converter that controls a collector current of a bipolar junction transistor (BJT) by controlling the base current to the BJT after having determined the gain of the BJT. A gain detection block determines a gain of the BJT during a first mode. A current calculation block generates a current setting for the base current based on the gain of the BJT determined by the gain detection block during a second mode distinct from the first mode. In some embodiments, the power converter may be included in a LED lamp system.

Abstract: A method of manufacturing a printed circuit board is disclosed. A conductive metal layer is formed on a first surface of a dielectric substrate. One or more vias are formed through the substrate. A conductive metal layer is formed on the first surface of the substrate and is patterned to form conductive traces on the first surface of the substrate. A plating mask is formed on the second surface of the substrate. One or more openings are formed in the plating mask to correspond to the location of the via(s). Conductive metal is deposited in the via(s) sufficient to substantially fill the via(s) and make contact with the conductive metal layer on the first surface and substantially to the level of the plating mask. The plating mask is removed from the substrate such that one or more conductive posts extend outwardly from the second surface of the substrate.
