🔌 Kester443-845 24-9574-7618 K100Ld Lead-Free No Clean Wire Solder: Affordable Low-Cost Alloy with .031" Diameter Review

I have read the MSDS and yes there are no references. It's a tin/copper eutectic, meaning a lower boiling point, but surprisingly better than the tin/silver eutectic at my university. My school's silver eutectic formed broken bonds every time, even if I isolated each vibration, but with this alloy I did not form a single broken bond. Be sure to get a computer fan and filters (a sock will do (with a smaller computer fan of course)) as flux produces many toxins in low concentrations which if…

This Lead-Free Solder (Kester K100LD) gives much better results than traditional SnAgCu (Tin-Silver-Copper); cures with a glossier finish; and usually cheaper too (excluding silver), but still expensive. When soldering difficult surfaces, be sure to add flux and use an iron 50°C above the temperature best suited for lead solder.

I'm a big fan of the Kester K100LD. This is a 63/37 type eutectic that I like to use. My only complaint about this solder wire is that the 275 flux core is weak and I often have to add more flux or the solder doesn't flow properly. The addition of Kester 951 Flux is a good combination with this solder. If you want the best lead free solder I recommend Kester 48 flux. The flux is much stronger and the solder flows better.

This material is excellent. It behaves very similar to normal lead solder. I was afraid to try lead-free solder because people said it gives off more flux smoke and is more difficult to work with than lead solder. I'm happy to report that this alloy is pretty good. I don't notice any unusual smoke either. I have a homemade smoke vent. I also bought a smaller diameter roll of the same material for finer work (Surface Mount Chips). I wish they would sell this stuff in smaller rolls at a lower…

My school's silver eutectic would break bonds every time, even if I isolated each vibration, but I didn't form a single broken bond with this alloy.
