SMTnet E-mail

The only place I ever used my SMTNET E-mail is through a couple of E-mails I sent to people that use this site. I sincerely hope that the used equipment guys are not passing out our E-mail addresses. Thanks for the response.

Solder Contamination

Why not go to VOC free flux. It is a water based no clean. Clean it when you need to and leave it when you don't have to clean. We have used it for several years. We do Military and Commercial - passes for all so far.

ICT Gage R&R

Electronics Forum | Fri Jan 31 12:13:31 EST 2003 | TN

We are having an issue with repeatability and reproduceability in our ICT process. The first pass yield is low but the retest yield is significantly higher. Has anyone out there have done a Gage R&R in their ICT process?

I agree with Dave, If you want to achieve S 20.20 you need the best. We were certified last year and due to the support we got from our vendor to guide us through what to do and not do as well as their ongoing training we passed first round.

BGA Rework

LITTLE problem!!! Consider removing and replacing the all BGA in one pass. Doing them one at a time [if that's the future you see for yourself] could get boring pretty quickly.

IT PASSED! no problems, and the customer has accepted it. Never underestimate the stretching of the rules when the scheldule is super tight. Thanks for all the replies on here, much appreciated. Right, onto the next problem..... Chrissie

Go to http://www.gsilumonics.com we use several of their systems for both paste and component inspection and week in and week out maintain a 99.85%+ first pass yield on a no post reflow repair line.

Steaming boards

Yes it is Di water and is tested after washing. The customers boards pass inspection testing before the wash but the customer likes to see them CLEAN.

Double reflowing BGA's

Electronics Forum | Fri Oct 10 13:35:56 EDT 2003 | swagner

Does anyone have any data about the dangers of reflowing BGA's twice? I have a customer that is concearned about cracking in the intermetallic layer after the second pass. Thanks in advance.
