Testing a board level interface connection that hap- pens to be the end of a Flex circuit is difficult to auto- mate. But such automation is essential to reducing errors and costs in a high volume electronics factory. On a flex circuit there are no rigid pins or surfaces with which to mate a test jig, only the plated metal traces on the highly flexible plastic substrate. The end of the flex is ticult to feed into an automatic tester by machine because it is often warped in one or two axes, with unpredictable severity. The plastic substrate material bends easily, requir- ing that it be grasped very close to the end, another di&ulty for a machiie.
