I do not think you can modify a 8*4 feeder to 8*2. Suppliers make a hell of a lot of money out of feeders so I would say they have that one covered. I think you will have to bite the bullet and buy 8*2 feeders. If you find out that you can modify

First, butget. Second, flexibilities. If you have tight butget, you better choose used SMT equipment instead of the new one. It will save you hundreds of thousand dollar. Second, if you change model more frequently, you do not have many to choose. Fu

What's the point of such a test? * If you are operating a board in an environment that keeps the board at a temperature that is close to causing delamination, why not design a board that can tolerate such an operating environment, rather than contin

Why is your big heavy BGA profile your fastest one? I'm guessing because it's hotter therefor faster? To achieve some kind of "balance" with the others. But you want those boards to get more heat, so you don't blance higher temps with faster belt, yo

whats the actual failure mechanisum your seeing which balls on the BGAs? my bet is its the ones on the corners, this is mainly due the the large heatsink on the top of the BGA when it starts to get hot it acts as a bi-metalic strip and lifts the corn
