RonE asked: How about Kester's NO CLEAN ? I used that to build my entire K2 as well as several other kits and 'projects' . The only drawback I noticed is that removing something after it is soldered in place requires a little extra care and time. My solder joints still appear fine after a couple of years anyway. I hope not to wake up one day to find them all eaten through! I didn't do any extra cleaning steps after soldering, that's WHY I bought the NO CLEAN
---------------------------- If you're talking about Kester 275 'No Clean', you should be fine. But you bring up an excellent point about trying new products: Check the manufacturer's data sheet! About the 275, Kester says: "The 275 residues are non-conductive, non-corrosive and do not require removal in most applications. The flux residues are comparable to a conventional RMA except that the 275 residue is clear and colorless." The data sheet is available on-line at: http://tinyurl.com/7o35n . Compare that statement with their 331 "water soluble" flux: "The 331 flux residue is conductive and may cause corrosion of metal parts over time." I believe that's where some have stumbled - thinking that "water soluble" would be better than rosin-based fluxes. The world of electronics has changed. How we solder at our benches is not how most soldering is done these days. Various machine techniques are used that solder boards more quickly and reliably, but they do it differently. For example, machine soldering is often followed by a very effective and complete machine washing of the board. In that environment, solders can be used that are absolutely deadly to circuits if used for soldering at the bench without access to proper cleaning facilities. The Kester web site has full info on all of their products at http://www.kester.com. It's important to note where they expect each product to be used, especially if one reads the short marketing blurbs instead of the data sheet.
