These residues are extremely water miscible BUT you will probably need the extraction of heated IPA/Water to get the porous resist to release the residue quicker than it would do releasing it naturally in the field. Why dont you try to soak the circu

Consider an adjustable (or fixed) process carrier then. It could offset the board so that your component is better centered. I have used Pentagon EMS for such carriers in the past. They are pricey, but last forever. We were a contract house, so the c
