Solder wicking up on connector leads

Electronics Forum | Tue Sep 16 17:03:34 EDT 2014 | rangarajd

We have an issue with solder wicking up the leads/ inside terminations on an SMT connector. The solder coverage is sometimes over 50% of the connectors inside pin length. The terminations are gold plated. Is there an IPC spec for acceptability? Plea

A good resource for implementing a BGA assembly process is: IPC-7095C Design and Assembly Process Implementation for BGAs Lots of valuable information in that publication.

What to look for in a BGA Lab analysis

Looking for better design information than is contained in IPC 7525A. Specifically the minimum trough width and length of the step to achieve the necessary paste reduction.

Components near breakouts

Electronics Forum | Tue Dec 01 17:43:35 EST 2015 | barryg

Hi all, I was wondering if there are guidelines for how near components are to breakouts, and orientation of components near breakouts? Does IPC or other address this? We are sometimes approached with some crazy PCB layouts with multiple PCB's per ar
