Abstract

See full text

Described herein is a multilayer flex circuit having a first dual flex circuit and a second dual flex circuit where each one comprises an outer metal layer, a base insulation layer, and an inner metal layer. The base insulation layer is disposed between the outer metal layer and the inner metal layer. The inner metal layer of the first dual flex circuit is configured to face toward the inner metal layer of the second dual flex circuit. The multilayer flex circuit also includes a coupling layer that adhesively couples the inner metal layer of the first dual flex circuit to the inner metal layer of the second dual flex circuit. The multilayer flex circuit also comprises an electrically conductive material that electrically connects the inner metal layer of the second dual flex circuit to the inner metal layer of the first dual flex circuit.
