In the past, I have sent back old solder paste to our bar solder supplier with our dross. I got rid of old paste, didn't have to worry about scrapping hazardous materials and they paid us for the "scrap" metal. Just a thought.

To: [log in to unmask] Cc: [log in to unmask] Hi Steve - Well, your wave solder pot will get pretty messy, definitely smell bad/different for a period of time and you will generate quite a bit of excess dross but I believe that as long as the solder alloy originally met the ANSIJ-STD-006 specification requirements you won't introduce any metallic type contamination that would cause you solder joint reliability concerns. Have fun(??), wear a mask, and let us know what happens.

Author: [log in to unmask] at ccmgw1 Date: 12/12/96 3:42 PM Good day all! This might seem like a pretty dumb question, but I was wondering if there's anything wrong with putting old solder paste in yer' wave solder pot? I was feeling bored the other day, so I cleaned out our solder paste 'fridge, and I've got some jars of a bunch of different samples of no-cleans and water solubles that were played around with in the past, and I just want to get rid of them before an operator grabs one and uses it. They're all the same alloy (63/37) but there are different flux types. We're in a water soluble process now, and we don't build missile guidance systems, just class-II stuff. I wouldn't think it would hurt anything, but I don't wanna' do it if there's something I'm not thinking about and I wind-up contaminating the pot somehow... (BOY, the operations boss would have my "keester"!!!) Any problems with doing that? I mean with adding old paste to the solder pot? NOT with kicking my keester if I contaminated the solder pot...heck, I would kick my OWN keester if I did that...heh,heh... __\/__ . / ^ _ \ . |\| (o)(o) |/| #------.OOOo----oo----oOOO.-----# # Steve Gregory # # [log in to unmask] # # # #________________Oooo.__________# .oooO ( ) ( ) ) / \ ( (_/ \_) *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * *************************************************************************** ------------------ RFC822 Header Follows ------------------ Received: by mke9.ra.rockwell.com with ADMIN;12 Dec 1996 19:59:58 -0600 Received: by moat.ra.rockwell.com; id TAA28256; Thu, 12 Dec 1996 19:59:57 -0600 Received: from ipc.org(168.113.24.64) by moat.ra.rockwell.com via smap (3.2) id xma028226; Thu, 12 Dec 96 19:59:30 -0600 Received: from ipc.org by simon.ipc.org via SMTP (940816.SGI.8.6.9/940406.SGI) id TAA21553; Thu, 12 Dec 1996 19:46:29 -0800 Resent-Date: Thu, 12 Dec 1996 19:46:29 -0800 Received: by ipc.org (Smail3.1.28.1 #2) id m0vYL3J-0000b4C; Thu, 12 Dec 96 18:00 CST Resent-Sender: [log in to unmask] Old-Return-Path: <[log in to unmask]> Date: Thu, 12 Dec 96 17:00:19 cst From: "ddhillma" <[log in to unmask]> Encoding: 67 Text Message-Id: <[log in to unmask]> To: [log in to unmask] Cc: [log in to unmask] Subject: Re: Assy: Solder Paste in Wave Solder Pots...
