Dave, what's wrong with snorting dross, it's great for the sinuses. What's the dental floss thing? (I lack imagination that MM has) I also appreciate the postings of the Moonster, Dave, and all the rest. Just wanted to ask a couple of inane questi

We don't do this, but if we had to and lacking better advice, for all components I�d dry pack according to J-STD-033, store in a low temperature and humidity controlled environment [maybe using some semicon fab inert storage cabinets], review the eff

Ron: You're really talking about a step-up stencil in the area of the BGA. I don't think your problem is a lack of solder, but who know? I think you should do some sections on returned boards from your customer to help determine the source of the

There is not enough time in the day to reliably hand solder these connections. Go buy yourself a solder fountain and spare yourself and your company the misery. Check the fine SMTnet Archives for sources of supply. Everything has a price. A solde

The previous entry is a very good point. After dealing with quad/tyco I have such a horrible taste in my mouth from thier lack of professionalism and dishonesty, that I wouldn't buy a tyco product if they paid me to take it. If I were a betting man,

Does anyone know how the Fuji IP2 can be adapted to place BGA's? The MTU places the chip on a carrier with suction in the center and it will not hold on to the BGA due to the lack of a flat surface on the bottom. I have had limited success building
