Abstract

The frame (1) consists of two mounting strips (3,3') linked together at regular intervals with transverse segments (4) between which are provided co-planar tongues each formed as one piece with a lateral mounting strip. The tongues (5) and (5') of each pair face one another without touching, one having a free end section (6) forming a mounting for the semiconductor crystal (2'). The other tongue at the height of its free end (7) has a pre-punched metal strip connector (8) which can be bent over so that it is in contact with the semiconductor crystal. This strip is located in the volume defined by the planes which enclose the long edges of the tongues.
