Check any inventory you have of 0805 3p9 capacitors manufactured by Exxxx in Europe. Batch # 1878029. Mixed values of 3p9 and 220pf are possibly on the one reel. I have never come across this before but we have found 5 reels where this is definite af

MAke a new stencile and have the aperatures reduced by 20% in X and Y. This has solved 90% of all solder balling issues I have ever dealt with. Be careful with your fine pitch and micro-BGA's. If you are not having problems with fine pitch and 1:1

We've recently gone through a spell with a Radial 5 where various pieces of the head tooling would break. We even found a piece broken inside of the wax seal straight from Universal. To keep it running, our techs put on tooling from a Radial 2 and

We had the same problems a few years back. We complained and they came back with the excuse that the supplier of the parts had made a bad batch. They sent us a new part in exchange of the broken one. When faced with premature breakage of parts that a

I feel your pain. Your company may already be using Kapton tape labels for their board serial numbers labels. Kapton is able to withstand repeated wash and heat cycles, and can be printed on a typical Zebra printer. The key to a successful and accura

I'm a Production Supervisor in a food plant in California. I'm looking for the same training video I once saw. It is very short and sweet and right to the point and opens the eyes and minds of the workers. If you find it please tell me where you foun
