PRINTED CIRCUIT BOARD WITH INTEGRAL STRAIN GAGE

摘要

A method for strain measurement measures strain in a printed circuit board having an integral strain measurement layer. The strain measurement layer includes an insulating layer having a top surface and a bottom surface, a strain sensitive layer of metallic foil adhered to the top surface of the insulating layer for measuring strain associated with the printed circuit board, and a copper coating disposed on the strain sensitive layer of metallic foil.
