One easy and often over looked step is to call out IPC-6012A compliance on the PO. You will also need to call out the class status. If you get in an issue regarding quality you will have a resource to fall back on. Sounds simple but ask your buyers

Hi all, There are no ground layers which makes the non wetting rate a bit confounding. The foam fluxer has not been cleaned in a while though, while there is a strong evidence of fluxing by running blank paper and looking up the top side

Yes. Heat reduces OSP solderability protection thickness. For instance, many OSP are shot at the end of the first reflow pass and the exposed copper is free to oxidize. If you're speedy, you can pull-off the second reflow cycle before the copper g

That your problem is not related to component solderability or wave process related makes us believe this has to do with bare board design. Look at how your designer did the thermal relief on the two pins that don't solder well. If you can't get a

We know virtually nothing about your process, but here's some guesses: * Turn-off the nitrogen * Change from Sn63 to Sn62 * Change to a low-tombstone paste * Change the thermal recipe: slower ramp, longer soak * Do a better job of placing components

And making a form with drawings of generic parts with blanks to fill in the data can help streamline the process as well. Has anyone met anyone who trusts datasheets more than the part itself? I always figured that the machine was verifying the par

Anybody knows how to use TiMMS Traceability? We're not using the application anymore 'cause we replaced it but server still up for record retention. The engineer who managed this one already left the company and now customer asking for the records. I
