| Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | 1. Cpk's

| Maybe I'm doing something wrong, but it seems to me that The Forum takes a lot longer to open up now. It also takes a lot longer to get back to the main Forum page, after reading an individual message, and hitting the "BACK" button. What's up? Is

Dave, I confess I was a tad too general and a bit too extreme describing the way ALL solder joints look on palladium coated leads. I should been more specific about the "pillow-effect". I've seen it regularly with palladium coated leads on small SOT

A reasonable assumption but it could be a reaction between your solder resist and the fluxes in the wave and reflow processes. The issue is, how will anyone really know? Then, are they likely to compromise circuit reliability? I have a method that wi

Check out the web site www.conceptronic.com I think you will see that the Conceptronic ovens are the best and most reliable over the long haul. Micron CMS has over thirty five of them and has stated that they were the most reliable and best vendo

Well, it appears after running both a bare and populated PWB we were seeing flux exhaustion on the uBGA. The problem apparently resulted by a recent maintenance effort where the air blowers in the reflow oven were replaced. The blower replacement m
