Claim Text:
1. A PCB page blank comprising: a flexible substrate having a first side and a second side opposite the first side; a curable adhesive adjacent the first side of the flexible substrate, the flexible substrate being configured to receive an opaque negative circuit pattern on its second side such that the negative circuit pattern obscures portions of the curable adhesive and gaps in the negative circuit pattern render other portions of the curable adhesive unobscured, the unobscured portions of the curable adhesive being configured to cure when exposed to light traversing through the gaps in the negative circuit pattern; a conductive layer adjacent the curable adhesive opposite the flexible substrate, portions of the conductive layer being configured to be bonded to the cured portions of the curable adhesive; and a conductive layer support adjacent the conductive layer opposite the curable adhesive, the conductive layer support being configured to be separated from the flexible substrate such that the bonded portions of the conductive layer are retained by the flexible substrate and other portions of the conductive layer are retained by the conductive layer support so that the flexible substrate, curable adhesive, and bonded portions of the conductive layer form a circuit board with the bonded portions of the conductive layer forming one or more circuit traces.
