Sean, We suggest having the PCB tested for ionic cleanliness. It is conceivable that though the visible flux residue has been cleaned, there is still invisible, yet ionically significant residue in the area of the board/part. We also suggest ensur

and one more thought about your original question, if the flux does look really strange and out of place, then inspect the reflow oven. A great amount of flux condensation in the reflow oven's cooling zone can cause crystalized flux to become airbor
