Cardas Solder

Leaded & Lead-Free Solder Products


George created our ultra pure, Quad Eutectic solder for the perfect joining of connector to conductor. Quad Eutectic solder contains a proprietary blend of silver, copper, tin & lead. Later, a lead-free, Tri-Eutectic version was created, to cover RoHS requirements in Europe.


Both Quad-Eutectic and Tri-Eutectic solder is available on rolls with rosin core.
