Custom Manufactured Back Flex Assembly Printed Circuit Board (PCB) for the Medical Industry

Badger Technologies custom manufactured this featured back flex printed circuit board (PCB) for a medical application. Beginning with a customer-supplied print, we began the manufacturing process by perfecting the design. Using polyimide with FR4 stiffeners, water-soluble solder-paste, and loctite 348 adhesive as the primary materials, we manufactured the PCB board in several steps.

The technological aspects of the PCB were supported using surface mount technology (SMT), and we loaded boards in an SMT board carrier. To cover the fingers, we used Kapton tape. After picking and placing, we hand-applied a pre-cut gasket, and then labeled, soldered, washed, and inspected the PCB. Once inspection was complete we pressed PEM nuts into two designated locations, applied a 2 to 3 mils thick conformal coating, and baked the PCB in a ventilated oven.

The PCB board was then subjected to materials and equipment and functional testing. The final component measured 6.75X2 inches with a .020-inch pitch device, and weighed an estimated .015 pounds. When we were certain we had met all of our client’s expectations and precise standards, we packed the PCBs in nested, conductive vacuum-formed trays and delivered it to them.
