Be careful of just reducing your aps. Too much can cause tombstoning if your print is slightly off or your placement isn't right on. Also be careful of the "pac-man" type of ap - it can lean to asty cuts if you wipe off your stencils by hand. Do

You really need your customer to provide a drawing of coated, keep out, and don't care. People new to coating don't realise the importance of having a don't care buffer area around the keep out areas. And conformal coating wicks up leads quite easil

Consider contacting other university SMT laboratories. Among them are: * Purdue University * Georgia Tech * SUNY Binghamton Actually, you really don't care what the machines do. You care about, 'Which companies will donate machines' [even if they'

I don't know wat are the types.. but wat I can tell you is you need care while profiling them. it needs a peak of around 215-220 if Sn/Pb.. at the ball. So the plastic on top will reach a higher temp. Care must be taken so that it doesn't roast. al

Just be careful on preheat. They tend to be weak on those small low cost machines. How well they work for you depends on what type of boards you plan to run. Large thick boards or high thermal mass boards will not likley run too well. Take boards to
