Patent ID: 7601560

Claim:
A method for producing an electronic circuit with which two semiconductor chips ( 46 ) with essentially the same structure are mounted on a surface ( 13 ) of a first conductor carrier ( 10 ) coated with strip conductors ( 16 ); both semiconductor chips ( 46 ) have a first surface ( 49 ) and a second surface ( 58 ); one semiconductor chip ( 46 ) is mounted—via its first surface ( 49 )—and the other semiconductor chip ( 46 ) is mounted—via its second surface ( 58 )—on the conductor carrier surface ( 13 ); the second surface ( 58 ) of the first semiconductor chip ( 46 ) and the first surface ( 49 ) of the other semiconductor chip ( 46 ) are interconnected by a lead frame ( 64 ) with an A.C. power supply connection ( 31 ), wherein the lead frame ( 64 ) is supported on support points that support the lead frame ( 64 ) and are not integrated in the electronic circuit before the lead frame ( 64 ) is mounted on the semiconductor chips ( 46 ), wherein immediately after the lead frame ( 64 ) is mounted on the semiconductor chips ( 46 ), connections ( 73 ) that serve no purpose in the circuit result between various contact points at which the lead frame ( 64 ) contacts various circuit elements and between the support points at a time when the lead frame is connected to the contact points and the support points, and wherein the connections that serve no purpose in the circuit are severed in a subsequent step.
