Hello all, I am a contract manufacturer and I got handed the project of looking up our parts and seeing what's lead-free and what's not. Well my question would be how is your purchasing dept handling this. I would like some input on this from alot of

We have a joint process with our purchasing department. They get notification from a supplier, which is passed to us. As a CM, we notify the customer and get permission to use it. Then we enter a new part number with a special suffix indicating le

If you know you have cleaned any flux residues that were under there you could consider a bead of an electronic grade RTV, such as RTV3145. If you trap any uncleaned residues under there you could have long term reliability problems. But, like Dave

I'm not sure if I understand the question correctly... Mainly, drill the mushroomed end of the rivet with a drill bit that is slightly larger than the shaft size of the rivet and remove the cover. Then, you should have easy access to what you need t

I can't see how prompt washing of the boards could cause a problem in X7R but not in Y5V or NPO. Yes, if you dropped a board into the wash straight out of the oven without letting it cool down then it's not going to like it, but surely no-one does t

It could be lots of things. You're not helping to narrow those alternatives. So, consider taking a sample to: * An analytical laboratory. * Teachers in the chemistry department at a local university. Kester recommends the following independent la

Hello Chris, To be honest, it's hard to believe you could not bond to ENIG at all. Yes, the gold layer is thin and hard, but it just narrows the process window and does not make the bonding impossible. I say this, because we have been using TS gold w

The 740 and 760 basically have the same specs as far as component ranges: 0402-50mm components. The 760 is a bit more accurate and the vision system is better. The 740 was designed when BGA weren't really around and so it can barely vision center b

Yes Rick, you are correct, Zevatech HBA, PPM7 & > PPM9 were all designed and built by Swiss. That > was a long long time ago. Sorry, I guess I forgot about those old beasts. Then don't forget about the good old CATs and Microns made by Zevatech
