ABSTRACT:
Certain regions of a printed circuit assembly having mechanically laid wires are formed of two parallel sheets of polyimide film, the circuit assembly being flexible in those regions. The edges of these sheets of film are secured in the region of the edges of the rigid parts of the assembly by means of thermally activated adhesives. In the flexible regions, the wires are embedded in a thermally activated adhesive layer held between the two sheets of polyimide film. This adhesive layer, unlike adhesive layers on the rigid parts, contains no fabric.
