Abstract:
1. A method of producing a circuit board comprising: (A) providing at least one lead frame comprising a lead frame perimeter and a plurality of leads extending from the lead frame perimeter; (B) providing at least one circuitry layer over the at least one lead frame such that the circuitry layer covers at least a portion of the lead frame perimeter to produce a layered assembly, the circuitry layer comprising one or more conductive traces; (C) bonding the layered assembly; (D) forming at least one electrical connection from at least one of the conductive traces to at least one of the plurality of leads; (E) exposing one or more of the plurality of leads to define a perimeter of the circuit board, the one or more exposed leads extending outward of the circuit board; and (F) removing the circuit board from the layered assembly, wherein the removed circuit board comprises the at least one electrical connection.
