John , I had some experience of selective solder in a high throughput environment and though the quality of s/s was good , the throughput was not . So if throughput is an issue , forget it . I would go with the hand-solder option , although as has be

Most LCD manuf. specify not to wave or reflow. I believe this is because of the prolonged exposure to the preheat temp. However, about three years ago, we were running about 350/wk of a 40P DIP LCD through the wave with no fallout. It did stress t

As you probably have discovered, the cost of x-ray inspection systems can run anywhere from $35,000 to $350,000 or more depending on if you want an In-line or off-line system. Assuming ,in your facility, you want an off line system, then the next con

We have an issue with our Seho Wave solder machine. The machine is an 8040C, early 90's model. The problem is that continues to heat the solder up, even once it has reached its specified temp. If we set it for 250 degrees, it will go to 250 then c

Once you verified for correct profile ( consider CTE mismatch) make sure before you remove PBA from fixture, the temperature is almost at room temperature. If by removing PBA from fixture,and the PBA gets a little bent (warped) just in the area where
