Thanks for your help. Solved it - The spindles on the head were stiffer than the other heads, so greasing it fixed it.

Aside from a visual first article to IPC 610, what inspection criteria do people put in place post wave solder (pre clean)? Thank you

If you are 100% inspecting, then all assemblies should be inspected to IPC-A-610 not just the first one. It sure would be nice if assemblies # 2 - 1000 were exactly the same as the first article, but they aren't.

You may want to try reducing the large center aperture on your stencil to 50-70% of the area of the pad. This is what we do with QFNs and it may be applicable in this case also.

Try: http://www.circuittechctr.com/products/201-5100.shtml I've never tried it, but it looks like it should do the trick.

I have tried this product and one from Kester with mixed results. Just follow the directions exactly. If it says rub the leads with the swab for 60 seconds, do it! Good luck!

Have someone you know but the sales guy doesn't know you know, ask for the same part with no lead. I would not be suprised if the sales guy sang a different tune then. Stephen

We agree with Steven that there must be a way to finagle the imformation from the supplier. Baring that, go to the chemistry laboratory at your local university and arrange for a chemical analysis of the component leads.

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.

Also look at second user prices & numbers of machines available - this will tell you how the industry as a whole receives them. (i.e. lots available cheaply = not good).
