Cleanning no clean residu

Electronics Forum | Fri Oct 19 11:51:25 EDT 2007 | rgduval

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean

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

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

Bruno The real question about your troop using Kester 951 wave solder flux on boards is: how is the flux applied and controlled. See, when you apply this flux with your wave solder fluxer, it is ideally applied in a metered fashion with your fluxer

Matt solder mask finishes gives the widest process window in view of potential amount of residues when using No-Clean. Shiny (glass like) finishes are more sensitive to residues due to lower surface area compared to matt finish. If the shiny finish i

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon
