METHOD OF FORMING A FLEXIBLE PCB

摘要

The method is for manufacturing a flexible printed circuit board with excellent lamination strength, heat-proof and chemicals-proof ; press and heat by 10~100N/cm2, 200~250deg.C a heat-proof and non conductive film, a metal lamination and some heat-hardening adhesives between them on belt press plate propelled by a caterpillar belt, then compress for 1 and half minutes - 2 minutes and 20 seconds, and then cool down to 10~25deg.C keeping the compression.
