Why would anyone wants to use either Auger or SIMS on that kind problem? :-)

Subject: [TN] HAL-Leaded assembly



Hello everybody, I am looking for some knowledge on what I see is a basic type problem that is driving me crazy. I am a sales guy who covers a sizable territory and in that territory for a PCB manufacturer (yes one of those) I have one account that I have been working with for about 4 years now that continuously has issues assembling both hand assembly as well as pick & place. 

The surface finish is HAL (leaded) this is a military account that is pretty well structured in their processes. What I get told is that there seems like a contamination is on the surface when they scrub the surface it makes it better but not 100% better.They have sent back samples for us to look at , we saw nothing on the surface no contamination nothing wrong at all. 

If this was one of a few that has the same or similar issues it would make some sense and I could go to the people I work with asking them to look into this issue. But it is the only company that has this issue. 

 Has anybody seen a similar type of a situation before? Understood that you cannot fix this but would appreciate advise as to where to look so hopefully this can be solved. 

Thank you.
