Patent ID: 10978770

Abstract:
A high frequency flexible flat cable includes a first metal isolation layer, a first low-k dielectric adhesive layer attached to one side of the first metal isolation layer, a second low-k dielectric adhesive layer attached another side of the first metal isolation layer and at least two conductor layers respectively attached to the first low-k dielectric adhesive layer and the second low-k dielectric adhesive layer. In addition, the high frequency flexible flat cable further includes a third low-k dielectric adhesive layer, a fourth low-k dielectric adhesive layer, a second metal isolation layer and a third metal isolation layer. The second metal isolation layer and the third metal isolation layer are respectively adhered to outsides of the conductor layers by using the third low-k dielectric adhesive layer and the fourth low-k dielectric adhesive layer to adjust the impedance of the high frequency flexible flat cable according to requirements.
