Kurtz had a guy that was great with the machine. I strongly suggest that you watch the wave height test a few times in the morning then at lunch and at the end of the day. Look where the solder goes up to on the probe. If it doesn't work consistent

They probably the same. Most likely someone is saying immersion gold [immersion Au] as a short hand for ENIG [ Electroless Nickel - Immersion Gold]. It is very uncommon to plate gold directly on copper, because gold and copper form a brittle interm

Any one using SPC to monitor their wave solder process? My point is collecting defects and using a scatter plot is useful but only after a problem occurs. SPC's true function is to warn of impending problems that are about to occur. Can SPC really

Most of these chemical swabs were developed to assess solder used in water supply piping. So, they are a really broad, gross test. If they tell you there's lead, there's probably lead, otherwise you're just guessing.

Give your current supplier a shot. They probably can do a good job for you. Most wave solder pallet suppliers make SMT pallets just to stay in business.

If I have a leaded board (PCB) and the only component that I have to repair it is a lead-free BGA, what type of solder do I use, leaded or lead-free?

We produce a board right now with a QFP that has 20 mil pitch and we are seeing problems with the solder deposition. I believe it to be a cleaning issue which we are addressing. Soon we will be pasting for bga's. Is there a problem with using inter

Hi, We have had a few vendors push automatic solder paste inspection devices on us in the past, and I have resisted until now. However we have a new product with a micro BGA on it, and I am worried about yield, so am considering it seriously for th
