Rear Adhesive Flex Printed Circuit FPC Polyimild Flex Pcb Material

FPC Flexible Circuit Board PI flexible PCB with rear adhesive

 

Understanding key components about flex PCB manufacturing are attachment pins which are pins can be added as conductor extensions, solder pins or other options. Placing adhesive in key locations allows improvement in circuit placement and mounting. With increasing concerns with electromagnetic interference and emissions from circuits, shielding specifications can reduce these risks. On single-sided circuits, conductor traces and spaces are available in .002”. On double-sided and multi-layer circuits, conductor traces and spaces are available in .003”-.004”. Connectors are flex circuits with assembled connectors allow for faster assemblies. Stiffeners are used to rigidize circuits in the component areas. Stiffener frames to assist wave soldering, clips apart and folds into position. Flex interconnects are used to connect rigid boards together allowing folding and positioning to solve high-density packaging problems.
