Work Board Holder for Flexible Circuitry

Work board 2 functions to hold flexible circuit 1 flat to provide compatibility for automated/robotic assembly/handling during the manufacturing processes of building a populated working flexible circuit 1.

Work board 2 includes work board frame 2A which has two tooling pin location holes 4 to locate the loaded work board 2 at each manufacturing line station. The location holes 3 receive pins 5 that locate flex circuit 1 to work board
2. Clearance holes 9 allow work board 2 to be picked up on hooks and run through cleaner solutions during manufacture. At each of the four corners of work board frame 2A, there is a spring 6 loaded low profile slider 7 that hooks into holes 8 in flex circuit 1 to provide continuous tension on all four corners during the manufacture of a populated flex circuit 1, including a vapor phase solder reflow station.

Flex circuit 1 has six holes 8 and 8A at predetermined locations to mate with features on work board 2. Two holes 8A are used to locate flex circuit 1 to work board 2. The four holes 8, one in each corner, are hooked by low profile spring- loaded sliders 7 so that tension can be applied to flex circuit 1 to hold it flat during manufacturing processes.

Slider guide screws 10 extend through each of sliders 7 loosely so that the slider 7 can move on the screws 10 and also extend through springs 6 into slider mounting block 11 which is fixed to frame 2A by mounting block screws 12.
