Abstract: An inductor, a semiconductor component including the inductor, and a method of manufacture. A leadframe has a plurality of conductive strips and a flag. A ferrite core is mounted on a die attach material disposed on the conductive strips and a semiconductor die is mounted on a die attach material disposed on the flag. Wire bonds are formed from the conductive strips on one side of the ferrite core to corresponding conductive strips on an opposing side of the ferrite core. The wire bonds and the conductive strips cooperate to form the coil of the inductor. Wire bonds electrically couple one end of the inductor to leadframe leads adjacent the semiconductor die. Wire bonds couple bond pads on the semiconductor die to the leadframe leads coupled to the inductor. An encapsulant is formed around the inductor and the semiconductor die. Alternatively, a stand-alone inductor is manufactured.

Abstract: A method of manufacturing a semiconductor component includes coupling a clip bond (230) from a semiconductor chip (120) to a lead frame (110) and dividing the clip bond into at least first and second portions separated from each other.

Abstract: A lead frame for assembly of semiconductor devices allows the wireless bonding of a die thereto. The lead frame includes a plurality of conductive leads the near ends of which are arranged together in a predetermined pattern that defines the die mounting area. The near end of one of the plurality of conductive leads is extended to extend inwardly of the die mounting area and is stamped to produce a stepped down portion with respect to the remaining end portion thereof. The near ends of the plurality of conductive leads, as well as, the remaining near end portion of lead having the stepped down portion are solder clad. In the assembly process, solder paste is dispensed onto the stepped down portion and the die is placed on the near ends of the conductive leads. The solder paste holds the die in place prior to reflow of the solder clad.

Abstract: A lead frame for the assembly of thin small outline packages incorporating a semiconductor circuit is provided in a generally rectangular form including a plurality of conductive leads opposing one another about the longitudinal sides of the lead frame and a die mounting portion centered therebetween. In addition, a pair of leads is provided at the distal ends of the lead frame which are stamped in a general “S” shape. These stamped leads extend downwardly from the lead frame and are within the footprint of the lead frame. The footpads of these additional leads remain exposed as the lead frame is encapsulate in a plastic molded package and are level with the bottom of the molded package.

Abstract: A semiconductor package (8) with a die (10) having die pads (16) coupled to inner ends (22) of interconnects (20), the die (10) and the interconnects (20) are molded in mold compound (30) with mounting surface (12) and outer ends (24) exposed. A semiconductor die has an interconnect surface opposite the mounting surface.

Abstract: In order to package an electronic component, a leadframe is provided having at least one flag portion (2) and at least one lead portion (7) extending towards the flag portion (2). The lead portion (7) includes an end portion (10) of reduced thickness adjacent the flag portion (2) and a channel (9) between the end portion (10) and the rest of the lead portion. The leadframe is etched to form the channel (9) and the end portion(10), which together form a locking step. The electronic component (3) is then mounted on the flag portion (2) and electrically connected to the end of the lead portion (7). The electronic component (3), the electrical connection (5), at least the end portion (10) and the intermediate portion (9) of the lead portion (7) and at least part of the flag portion (2) are encapsulated in a plastics molding compound, which enters and fills the locking step, and is then cured.

Abstract: A leadframe (1) includes a main frame having longitudinal outer rails (4) and a number of sub-frame (8) separated from the main frame by a slit (6) extending around at least part of the perimeter of the sub-frame (8). A plurality of flag portions (2), on which a semiconductor die is to be mounted, extend from the mainframe and a plurality of lead portions (12) extend from the sub-frame (8) towards the flag portions (2). The sub-frame (8) is bent twice in a zig-zag fashion so as to be in a plane parallel to that of the main frame so that the corresponding flag and lead portions overlap without affecting the dimensions of the outer edge portion of the main frame.
