Really, if you start out from the beginning planning to clean the boards, then DON'T use the no-clean flux! The way that stuff is made, it leaves a hard, low-solubility residue that takes a LOT of effort to get clean. If you plan to clean, use a wa

Hello I thind you are same Mr. Scott from whom once i had purchased inspection system in M/s Evershine India. Regarding your query, we want to inform you that we are mounting BGA with water solubel flux (special flux paste) from alpha metals and the

No-Clean fluxes are difficult to clean off boards. Cleaning effectivness depends on the washer, the chemistry, the flux type, number of reflows, and the time between reflow and washing. White residue is flux residues that have started to break down b

We recently changed to an Amtech no clean paste and flux that is washable. So far excellent results. Far superior to the water soluable paste we were using. Fewer solder balls, longer life in printer, boards can be left up to 5 days and still come

| | | Gian | | | | | | You alarm me when you talk of white residues in a "no-clean" process. This should not happen. It sounds like you have compatibility problems between different residues and/or a poorly polymerised solder mask. | | | | | | Ther
