This solder alloy from STANNOL
Ecoloy TSC305 is a lead-free solder alloy from STANNOL with the composition Sn96.5Ag3.0Cu0.5 (DIN EN ISO 9453, alloy no. 711). The product is described as a solder alloy intended for electronics assembly and is stated to have a melting range of 217–220 °C in the manufacturer's technical documentation.Technical overview
- Composition: Sn96.5Ag3.0Cu0.5 (stated in manufacturer's material).
- Melting range: 217–220 °C (stated in technical datasheet).
- Recommended solder pot temperature for wave soldering: approx. 265 °C (manufacturer's recommendation).
Typical applications
- Wave soldering: Ecoloy TSC305 can be used in wave soldering, where the manufacturer recommends a solder pot temperature of approx. 265 °C and states that the reduced copper content can extend the lifespan of the solder pot.
- Selective soldering: The alloy can also be used in selective soldering systems (stated by the manufacturer).
- Rework and hand soldering: The datasheet mentions use for rework and hand soldering with adjustment of flux content and temperature profiles.
Further notes
The manufacturer describes the advantages of the reduced copper content, including extended operating time for the solder pot compared to conventional SnAgCu alloys. The datasheet recommends regular analytical control of the copper content in the solder pot to keep copper below 1% to avoid an increase in liquidus and potential soldering defects. The choice of flux and adjustment of process parameters are recommended when transitioning to lead-free production.
