This R-TECH SAC305 solder (MPN: 857021) is designed for electronics professionals and hobbyists needing reliable solder joints with reduced flux spatter. Its 2% L1 flux and low halide content ensure excellent wetting and minimal residue, but the 0.7mm diameter may require more frequent reapplication for larger projects compared to thicker gauges.

SAC305 refers to the alloy composition: 3% Silver (Ag), 0.5% Copper (Cu), and the remainder Tin (Sn). It is a common lead-free solder alloy.
L1 flux is a type of rosin-based flux that offers good activity and low spatter characteristics, suitable for many electronic soldering applications.
This SAC305 solder is specifically designed for electronics. It is not recommended for plumbing applications, which often require different types of solder and flux.
For most electronics applications, flux residue can be cleaned using isopropyl alcohol (IPA) and a brush or lint-free wipe. Ensure the board is completely dry before powering on.
The melting point of SAC305 solder is approximately 217°C (422°F). This is the temperature required for it to transition from solid to liquid.
It is generally not recommended to mix leaded and lead-free solder in the same joint, as it can compromise the joint's integrity and performance. Use lead-free solder for lead-free components and boards.
When stored properly in a dry, cool environment, R-TECH SAC305 solder typically has a long shelf life, often several years. Avoid extreme temperatures and humidity.
Ensure the soldering iron tip is clean, tinned, and at the correct temperature for lead-free solder. Verify the component and PCB pads are clean and free of oxidation.
While this solder has low halide content, ensure the soldering iron temperature is not excessively high. Clean the tip regularly.
This can indicate insufficient heating or a disturbed joint during cooling. Ensure consistent heat application and allow the joint to cool without disturbance. Check for oxidation on the surfaces being soldered.
Setup: No specific setup is required. Ensure your soldering iron tip is clean and tinned before use. Use appropriate ventilation, such as a fume extractor, when soldering.
Compatibility: This solder is designed for lead-free electronics assembly and repair. It is compatible with most standard lead-free soldering irons and processes. Ensure your equipment can reach the necessary temperatures for lead-free alloys (typically above 217°C / 422°F).
Care: Store the solder reel in a dry, cool place away from direct sunlight and excessive humidity to maintain its quality. Keep the reel covered when not in use to prevent contamination.
