Is anyone populating boards with LGA's on a production basis? If so, what process issues should I be concerned with and what challenges do they present that would be different from BGA assembly? Thanks. Steve

The white residue can be caused by putting Alcohol on the no clean product. Some people will attempt to clean an area they have reworked.

We are currently having a lot of problems in Circuit testing many of our product due to the use of our no clean flux. We don't clean our board in any way. How is the industry dealing with this problem? Or are we unique?

I've run up against the same problem that I know many of us in the industry face; our management wants to obtain a "world class" level of production. This has come up before, and I've looked through several responses dealing with ppm (dpmo), failure

I'm looking for practical proceedures to do the following: How to qualify epoxy in our process. One supplier vs. another. How to qualify wave solder and flux in our process. One supplier vs. another. Any and all advice is welcome.

Good question * Rich lathrop at Heraeus wrote a good paper on quantifying the printability of adhesives. You can probably find it on their site. * J-STD-001 is the baseliine for qualifying processes. Good luck
