One diagnostic tool that I have found useful in the past is the "hot plate test". Place suspect components and/or PCB's on a hot plate and turn it on High. Then observe. Granted the conditions on the hot plate are not the same as in a reflow oven,

Good Morning Here are a few thoughts. When mfg large flex circuits you will need to fixture them to create a stable production environment. As such, the foot print fo the product grows. So you may require systems that can handle 20 inch width by 38 i
