Abstract:
A method for fabricating a circuit board assembly comprising the following steps:a) providing a flexible circuit comprising:i) a dielectric layer that is transmissible to actinic radiation of a predetermined wavelength, said dielectric layer having two opposing surfaces; andii) at least one conductive layer disposed on at least one opposing surface of the dielectric layer, said conductive layer having at least one opening therethrough for allowing passage of the actinic radiation through said flexible circuit;b) providing a substrate comprising a top surface defining at least one channel and a mating region for mating with the flexible circuit;c) dispensing an adhesive into the channel of the substrate, said adhesive being curable by radiation of the predetermined wavelength;d) placing the flexible circuit on the top surface of the substrate such that at least a portion of at least one opening in the conductive layer of said flexible circuit coincides with and overlays at least part of at least one channel in said substrate;e) directing actinic radiation of said predetermined wavelength through the opening in said conductive layer and onto the adhesive in said channel, wherein said actinic radiation is directed through said opening for a sufficient time to cure the adhesive and to bond the flexible circuit to the substrate.
