ABSTRACT:
A flexible circuit board assembly (10) includes a flexible substrate (11) having first and second end portions (14,15) and an intermediate portion (16). Conductive metalization interconnect paths (17) extend between the substrate end portions (14, 15) and across the intermediate portion (16). The substrate first and second end portions are mounted to first and second end portions (21, 22) of a rigidizer plate (20). Stiffening material (35) is provided on the flexible substrate intermediate portion (16) to define stiff (36, 37, 38) and less stiff (39, 40) paths that extend across the interconnect paths (17) and the substrate intermediate portion (16) and define desired bend curvature characteristics for the flexible substrate intermediate portion (16). A method utilizes this structure to provide a flexible circuit board assembly (10), preferably with a bent rigidizer plate (20).
