IPC: H01B7/08
Filed: 1989-02-14
Abstract: PURPOSE:To obtain a flexible printed-wiring board which is strong against thermal stress and is not easily disconnected by forming a conduction circuit with a shape memory alloy. CONSTITUTION:A conduction circuit is formed by a shape memory alloy which is an alloy returning to the original shape before deformation by heating even if the formed shape at high temperature may be deformed at normal temperature. That is, a foil of shape memory alloy is adhered to an insulation base by using an adhesive and unneeded part is eliminated by etching. Thus, distortion caused by thermal stress is absorbed by conduction circuit. Therefore, a flexible printed-wiring board which is strong against thermal stress and is not disconnected easily can be obtained.
