ABSTRACT:
A lead frame facilitates the handling, positioning, attachment, and/or continued integrity of multiple dies, without the use of multiple separate parts, such as jumpers. The lead frame includes a number of structures, each of which is attached to at least one lead. At least one receiving surface, arranged to receive a die, is associated with each structure. When dies are disposed on the receiving surfaces, anodes are similarly-oriented. A number of fingers are attached to the lead frame, and one or more electrode contact surfaces are attached to each finger. Each electrode contact surface can be positioned (for example, bent) with respect to one receiving surface, to facilitate electrical connection between the anode of a die and a lead. The lead frame may be used in connection with surface- and through-hole-mountable electronic devices, such as bridge rectifier modules.
