Pete, Top-side temp might be an issue. What's the easiest way to check it? I seem to recall some thermal decals that we used to use a couple of jobs ago. I spoke with the flex manufacturer, and they recommended 4 hours at 250 degrees pre-process

Seems like every week there is a new thread where someone is asking which AOI to purchase. I hope you realize that AOI equipment is not cheap. This company is in profit-assurance mode for the first 4 quarters of this year. As you know, when we ar

$100K for this entire line. We are thinking of getting a Chinese made reflow oven that looks pretty good at $25K. Also, we need to deposit solder using a dispenser as stencil printing will be reserved only for higher volume boards. It will not be pra
