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..).

Thanks for that, I will look into it. Unfortunately the plant is in Sweden, however maybe I can get a sample from someone local there. Do you have any contacts?

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.

Thats funny, maybe so. Anyway, changing the ramp rates will probably be the first thing we will try next week in Sweden.

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.

Have you ever done QC type thinking on your problem or are you aware o fthe methodology? Do you run your plant in a clean room environment? Do you clean after reflow? If not Why? What sort of products are you running? What sort of oven are we ta

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.
