Hi Kathy, I am very interested in this as we have the following processes: 1. No clean smt - no clean wave solder - saponified wash 2. No clean smt - clean wave solder - aqueous wash. Could you please advise why this would be detrimental. Would this affect the reliability of the joints and if so is there a paper on this. Thanks for your help. Best regards Marc. -----Original Message----- From: Kathy Kuhlow [mailto:[log in to unmask]] Sent: Wednesday, January 30, 2002 2:20 PM To: [log in to unmask] Subject: Re: [TN] Flux residue with a no-clean process << File: TEXT.htm >> IPC-610 has no-clean residues as acceptable. Is it possible that flux may have been mixed with a washable? Washing a no-clean off is more detrimental than leaving it alone. Is the assembly conformally coated? Is the application intended to be in a wet or high humidity/moisture enviroment?
