If your component meets ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires, then the problem is at your customer's operation. If the problem is at your customer's operation, it's very difficult to anal

Yes, working with both the solder reps and the oven manufacture. It seems everything is in spec.

talk to who, and what product?

I thought it might be the oven too, except it seems the splatter is too small for drips from the oven, secondly, when I ran a couple of bare boards among the populated boards we saw no splatter or flux contamination. So it seems it comes from the bo

Your most likely ramping temp to fast and boiling the flux, or do have moisture in the fabs. BTW every solder paste rep has the solution until their product doesn.t work then they have excuses.

Sorry, I guess I don't know how to address an individual on this thread directly. The fella who represents the anti-flux solder paste - Graham Cooper.

Hello Greg, there are several things to be considered: I will start this investigation in the oven. Look in your cooling zones. Many ovens build up a lot of flux there(especially the ones with water cooling) and should be cleaned every so often.

Our company being an automotive supplier is all about quality control, not a clean room requiremen, This is a no clean process, all surface mount boards and Solitec ovens. Hopefully this answers your questions. Greg

I have never considered that before. I don't think so, but I will look at it closer. The reason I don't is that most of the micro spots are nearly all resin but I will look at this. I will try to attach a photo that shows the contamination

Have you re-visited your paste manufacturers profile requirements? Start there, adjust accordingly to critical components on the boards (ie LED's, moisture sensitive, etc..).
