Abstract: A process for deforming a flex circuit using a fixture assembly including a base plate having a recess, a wrinkle reducer plate, a stiffening block and a punch. The process including heating the fixture assembly; applying a force to the punch deforming the flex circuit into the recess in the base plate; holding the punch in contact with the flex circuit while heating the fixture assembly; cooling the fixture assembly with the punch in contact with the flex circuit; subsequent to cooling the fixture assembly, removing the force of the punch; and removing the flex circuit from the fixture assembly. The flex circuit having a recessed portion resulting from deforming the flex circuit into the recess in the base plate and a flat portion surrounding the recessed portion.

Abstract: A fixture assembly for deforming a flex circuit that includes: a base plate having a recess; a wrinkle reducer plate having a first cut-out portion aligned with the recess; a stiffening block having a second cut-out portion aligned with the recess and the first cut-out portion; and a punch to slideably engage with the recess, the first cut-out portion and the second cut-out portion; wherein, in operation, a flex circuit is placed between the base plate and wrinkle reducer plate and the punch extends through the first cut-out portion and the second cut-out portion to engage the flex circuit and deform the flex circuit into the recess so that the flex circuit has a formed section in the shape of the recess and a flat section clamped by the wrinkle reducer plate and the base plate.
