Abstract: Inductive electrical components fabricated by PWB techniques of ferromagnetic core or cores are embedded in an insulating board provided with conductive layers. Conductive through-holes are provided in the board on opposite sides of a core. The conductive layers are patterned to form with the conductive through-holes one or more sets of conductive turns forming a winding or windings encircling the core. The conductive layers can also be patterned to form contact pads on the board and conductive traces connecting the pads to the windings.

Abstract: In order to allow header-less connector pins to be directly surface mounted to a PCB, using a standard pick and place machine, a novel pin holder is used to hold the pin while in pockets or holes of a reeled tape and during its pick and placement by the suction head of the pick and place machine supplied with the reel. The holder is configured to permit standard pin spacings of a row of pins to match standard female connectors, and to allow observation of the pin during the placement process. Novel pin designs for use with the holder are also described.
