Mornin' Everybody!

Juan has sent me two pictures of the white spots he's seeing. They're at:

From what I'm seeing, I don't know if I'd worry about them that much...just as long as the board isn't covered with these spots. These look like bare boards that haven't had anything done to them yet. Am I correct? 

You might take one the boards that you see the spots in and run it through a reflow oven under a soldering profile and see if the spots get any bigger. If they didn't, I probably wouldn't worry about them.

In some PCB's we have detected white spots. Although I think these spots are not due to a delamination and the boards should be acceptable, I'd like to have your assessment.

Thank you in advance,
