Electrical circuits.

摘要

An electrical circuit is formed as a pattern of conductive ink (2) upon one surface of a flexible transparent substrate (1), the other surface of which carries a layer of contact adhesive (3) by means of which the completed circuit is attached to a support. The ink is screen printed to form an intricate pattern of conductors, and is cured at a low temperature to avoid damage to the substrate. The support can form part of the housing of electrical apparatus which is too inaccessible or awkwardly shaped for the circuit to be formed in situ.
