Hi there Steven ! Please allow me to share some of my problem we're facing here with you. Here are a few points that I suggest you should check on your current process:- (1)PCB - Component land partern design ? It is per IPC spec ? - Mask

If the white residue is from a no-clean flux or no- clean solder flux core you can leave it on the board. (Consult with the flux or cored solder manufacturer) Because after being encapsulated with conformal coating the residue is sealed from humidity
