Cardas Soldering Wire Quad Eutectic Silver Solder with rosin flux 1/4 lbs (113g) roll

As a ASEET electronics tech I been soldering for 40 years. This is easily the best solder Ive used. The flow out is fantastic and makes a cold solder joint impossible unless you screw up from a lack of solder skills. The silver content is perfect and is proven by the bright silver color of the joints and testing a 5 foot length with an ohm meter against the other brands. The Cardas shows the lowest resistance of any solder out there. Clean the soldered joint with a q tip and alcohol to see the proof. I add a dab of rosin flux on old solder joints with unknown solder and this solder flows and blends perfectly.
