What are the long term issues with high tin content solders on parts plated with silver over copper? Is it possible that the silver will be absorbed by the solder then over a long period of time the tin will react with the copper causing it to part

I can't tell you what's good, but I can tell you what's bad. We use JD Edwards. To give you an idea of how well it is suited to the electronics environment, most of the help screens, should you be able to find them, use recipes for bread and food

We have a Siplace S15 and I would like to know if it is possible to make it skip a part during the placement operation with out aborting the job? In section 5.4.4.4 of the user's manual it describes how to set a track to empty and proceed on with the

You have 2 groups giving us 'evidence' here: 1. the research companies who will do anything to scare us, just to make sure more research will be done, if they said everting was fine they'ld be out of a job in a sec. Ex: look at that paper, a leaded

Ah, I have 3 of these ovens. Not bad ovens at all. You mentioned a PLCC 64. Is this part having the delta T problem? If so, that seems odd. Without knowing your exact set-points, you could pump in more heat up front. Change blower speeds to hig

Hi guys, Has anyone ever had experiance with a Vision Master 150 ?, we have 2 onsite and I am trying to get accurate BGA paste height measurements from this machine, but both the machines are giving me results with huge variations, like +/- 0.2 thou

Not arguing dan, but are you positive that they are not copper? anyway, what is happening is as the parts sucks down onto the board from reflow the extra paste is notnecessarily sqeezed out but it has no place to go. So it will form this ball on th

As I recall, several years ago, Siemens was developing a tape splice detector for at least the 8mm feeders, this was coupled with a method of entering the number of components on the new reel. This in theory allowed the machine to give a warning bef

Great, just what we need - Psuedo science. To paraphrase: We tried 99.5Sn/0.5Cu & it didn't work so we couldn't be bothered to try any other lead free alloy. So give us an exemption else we'll bury you up to the neck in the stuff. I have no probl

Hi Steve, Nope, you phrased it perfectly, and I knew what you were asking. The equipment is very similar in concept, except on the fab side it has much tighter tolerances and a different blade type. If you want to see one, check out this page h
