Abstract
In a lead-frame configuration (1), which has a frame base (3) and a multiplicity of lead-frames (6, 7, 8, 9, 10, 11) connected with the frame base (3) and intended to hold a chip each, each lead-frame (6, 7, 8, 9, 10, 11) has two connecting plates (12, 13), and each connecting plate (12, 13) is connected with the frame base (3) via connecting webs (28, 29, 30, 31, 32, 33) and the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) delimit a bridging zone (34) which can be bridged using a chip and which is formed by only a narrow air gap (34) so that the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) about each other directly without a further intermediate section of the lead-frame concerned.

A lead-frame configuration (1) designed strip-like with a frame base (3) and a multiplicity of lead-frames (6, 7, 8, 9, 10, 11) connected with the frame base (3) and lying next to each other in the strip's longitudinal direction (2), of which each lead-frame (6, 7, 8, 9, 10, 11) is intended to hold a chip, where each lead-frame (6, 7, 8, 9, 10, 11) has two connection plates (12, 13) and between each connection plate (12, 13) and the frame base (3) is provided at least one connecting web (28, 29, 30, 31, 32, 33), and where each connecting plate (12, 13) is intended to connect with a connection of a chip and where the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) delimit a bridging zone (34) which can be bridged using a chip, and where the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) abut each other directly without an intermediate section of the lead-frame (6, 7, 8, 9, 10, 11) and delimit an air gap (34) as a bridging zone (34).
A lead-frame configuration (40) designed strip-like with a frame base (3) and a multiplicity of lead-frames (6, 7, 8, 9, 10, 11) connected with the frame base (3) and lying next to each other in the strip's longitudinal direction (2), of which each lead-frame (6, 7, 8, 9, 10, 11) is fitted with a chip (41, 42, 43, 44, 45, 46), where each lead-frame (6, 7, 8, 9, 10, 11) has two connection plates (12, 13) and between each connection plate (12, 13) and the frame base (3) is provided at least one connecting web (28, 29, 30, 31, 32, 33), and where each connecting plate (12, 13) is connected with a chip connection (47, 48, 49, 50, 51, 52) of a chip (41, 42, 43, 44, 45, 46) and where the two connecting plates of each lead-frame (6, 7, 8, 9, 10, 11) delimit a bridging zone (34) bridged by means of a chip (41, 42, 43, 44, 45, 46), and where the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) abut each other directly without an intermediate section of the lead-frame (6, 7, 8, 9, 10, 11) and delimit an air gap (34) as a bridging zone (34).
A lead-frame configuration (60) designed strip-like with a frame base (3) and with a multiplicity of lead-frames (6, 7, 8, 9, 10, 11) connected with the frame base (3) and lying next to each other in the strip's longitudinal direction (2), of which each lead-frame (6, 7, 8, 9, 10, 11) is fitted with a chip (41, 42, 43, 44, 45, 46), where each lead-frame (6, 7, 8, 9, 10, 11) has two connection plates (12, 13) and between each connection plate (12, 13) and the frame base (3) was originally provided at least one connecting web (28, 29, 30, 31, 32, 33) and where the originally provided connecting webs (28, 29, 30, 31, 32, 33) have been disabled, and where each connecting plate (12, 13) is connected with a chip connection (47, 48, 49, 50, 51, 52) of a chip (41, 42, 43, 44, 45, 46) and where the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) delimit a bridging zone (34) bridged by means of a chip (41, 42, 43, 44, 45, 46) and where the two connecting plates (12, 13) of each lead-frame (6, 7, 8, 9, 10, 11) about each other directly without an intermediate section of the lead-frame (6, 7, 8, 9, 10, 11) and delimit an air gap (34) as a bridging zone (34), and where for the lead-frames (6, 7, 8, 9, 10, 11) lying next to each other in the strip's longitudinal direction (2) a connecting strip (66, 67) is provided running in the strip's longitudinal direction (2) which is connected both with the frame base (3) and with each of the frames (6, 7, 8, 9, 10, 11) lying next to each other in the strip's longitudinal direction (2).
