DOUBLE-LAYER CIRCUIT BOARD MADE BY COMBINING SINGLE-LAYER CIRCUIT BOARD ONTO FLAT CABLE AND MANUFACTURING METHOD

摘要

A double-layer circuit board made by combining a single-layer circuit board (1) onto a flat cable and a manufacturing method. Specifically, the single-layer circuit board (1) is manufactured, the single-layer circuit board (1) is a conjoined flexible circuit board comprising a plurality of lamp strip circuit boards, an adhesive is intermittently printed on the back of the circuit board (1) at multiple positions, and multiple holes (1.4, 1.5) are punched out by using dies, wherein some of the holes (1.4, 1.5) are holes that narrow the edge of a single lamp strip or hollow out the middle of a single lamp strip, and some of the holes (1.4, 1.5) are spare holes for conduction of the flat cable; then, the flat cable is manufactured, parallel wires are pasted by using a film with glue to manufacture the flat cable, wire metal is exposed on the flat cable at multiple positions, then the flat cable is cut into multiple gaps (3.2), and the circuit board (1) and the flat cable are aligned and pasted together to form the conjoined flexible circuit board comprising the plurality of lamp strip circuit boards. The circuit board is layered at multiple positions, and the single-layer circuit board (1) on the front is narrowed or hollowed out, facilitating multi-directional turning installation at narrowed or hollowed-out layered positions when the manufactured single LED lamp strip is used.
