Patent ID: 8851356

Claim:
A method of connecting a plurality of flexible circuit boards together comprising the steps of: applying an amount of a solder paste to an upper surface of a second flexible circuit board wherein the upper surface comprises one or more pads configured to receive a component; holding an upper surface of a first flexible circuit board and a lower surface of the second flexible circuit board together, such that the boards partially overlap one another forming a lap joint; reflowing the solder paste with a heat source to bond the first flexible circuit board and the second flexible circuit board together to form a flexible circuit board strip having a length longer than either of the first flexible circuit board or second flexible circuit board separately; wherein reflowing the solder paste with a heat source results in solder flowing down through a hole in the second flexible circuit board; and confirming bonding of the first flexible circuit board and the second flexible circuit board together by inspecting the height of solder in the hole.
