Own mta® solder wires

mta® solder wires are based on moderately activated synthetic resin for professional electronics use. It is recommended for use on gold, HAL or chemical tin surface finishes. This alloy has been developed to achieve the lowest possible dissolution rate of copper and iron. Depending on the general conditions, an increase in the life time of solder tips of up to 50% is possible.

All material complies with the Directive 2011/65/EU (RoHS).

Sn96Ag3Cu1 (SAC 305) – high efficiency alloy

The alloy used here is close to the eutectic composed of tin, silver and copper. Typical application: due to the added silver,
it can be used more particularly in cases where an improvement of wettability is required.
