1. General characteristics

The solder was produced in the first smelt of tin, silver and copper. The composition of the solder complies with the ISO 9453:2014 standard. EVO solid flux is a “no clean” and based on rosin. The flux EVO is intended for manual and automatic soft soldering. The solder wire meets the requirements of the RoHS2 Directive.
