OSP Interval Times for Reflow

When using OSP coated boards, what is the maximum acceptable (and recommended) time interval between reflow of the "first" and "second" sides to ensure proper wetting?

Normally as quick as possible. Without knowing your reflow profile it would be nearly impossible to give an accurate estimate. Try with a group of scrap boards for 24, 48, 36 hours etc. until you reach a point you are happy with. But 48 hours should be the maximum you aim for due to potential variation on PWB
