I just brushed or dipped the parts followed by 2 rinses with R.O water. For disposel we neutralized the SolderNu with baking sod Charles Caswell -----Original Message----- From: Black, Paul [mailto:[log in to unmask]] Sent: Tuesday, March 11, 2003 9:55 AM To: [log in to unmask] Subject: Re: [TN] Kester Solder-Nu replacement Dear Technetters, We recently found some socketed PLLC's that were returned from customers with lead contamination. The parts are otherwise fine. Would Solder-Nu be a good candidate to remove this contamination? How is it applied? What methods) are normally used for disposal when the chemical is spent?

The SolderNu product was fluoboric acid based instead of phosphoric acid based. Kester is discontinuing the SolderNu product? Bummer, when used carefully the stuff was a nice tool to have in the solderability restoration kit! Dave Charles Caswell <CharlesC@FESCORP To: [log in to unmask] .COM> cc: Sent by: TechNet Subject: Re: [TN] Kester Solder-Nu replacement <[log in to unmask]> 02/26/2003 04:00 PM Please respond to "TechNet E-Mail Forum."; Please respond to Charles Caswell Sorry I don't have the msds anymore. I just remember it was phosphoric acid based. Smelled just like the descaler I use in my aqueous machine. So when I read that it was discontinued I dug into some parts we use for training and found some resistors that are pretty ugly. Soaked in descaler for about a minute, rinsed and tinned. It worked. If your quality dept. is like ours though it would be a hard sell.
