Abstract
Techniques are disclosed for making a flexible laminated circuit board using a metal conductor onto which a SMD may be attached. Conductive metal strips may be laminated to form a flexible substrate and the metal strips may then be perforated for the placement of LED package leads. The LED packages may be attached to the conductive strips using solder or a conductive epoxy and the upper laminate layer may include perforations exposing portions of the metal strips for the attachment of the LED packages. Alternatively, strings of LED packages may be fabricated by attaching LED packages to conductive strips and these strings may be laminated between flexible sheets to form a laminated LED circuit. Plastic housings may aid in attaching the LED packages to the conductive strips. The plastic housings and/or the laminate sheets may be made of a reflective material.
