At one point in time we were putting TI NanoStar parts on these particular boards. You don't want to attempt this at home! Thank God they took them off. Part was 1.45 X 1mm with 6 .1mm balls. They were a pain in the A$$. We had about a 90% success ra

I noticed on the floor that workers hand place some SMT parts becuase some parts that came in a tube (instead of on a reel) do not fit properly into the tube feeders. The tubes dont align properly in the feeders becuase of their size. Are there any

Recently I have been hearing and see this excess flux residue problem at several companies, US, Mexico, and Japan. It seems to have increased recently. In fact, it seems so common that it seems normal, but if everything is correct, a re-flow oven sho
