Lead-free cored wire Sn96.5 Ag3.0 Cu0.5, diameter: 0.8mm, 500g spool – professional standard of precision and durability

Optimal composition and modern formula

The lead-free solder wire Sn96.5 Ag3.0 Cu0.5 (SAC305), with a diameter of 0.8 mm and 3.5% ROL0 flux content, has been developed for applications requiring maximum reliability and process repeatability. Produced from high-purity metals under controlled conditions, it ensures solder joints with excellent electrical conductivity, high mechanical strength, and clean, aesthetic finish. The minimized oxide and impurity content reduces the risk of soldering defects, resulting in greater reliability of finished devices.

Advanced 3.5% ROL0 flux

The ROL0 flux, compliant with J-STD-004, is rosin-based, halogen-free, and classified as no-clean, leaving transparent, non-corrosive, and electrically safe residues. The higher flux content (3.5%) improves wetting performance, facilitates soldering on oxidized pads or challenging geometries, and speeds up the soldering process. No post-soldering cleaning is required, which increases efficiency and shortens processing time.

Performance and technical parameters

The melting range of 217–221 °C provides flexibility for various substrates and components. The wire features rapid wetting and excellent adhesion to soldered surfaces. As a result, joints are uniform, splash-free, and free from excess dross, suitable for both manual assembly and automated soldering systems.

Form factor and work convenience

With a diameter of 0.8 mm, this solder wire offers an optimal balance between precision and feeding speed. It is ideal for through-hole technology (THT), SMD assembly, and a wide range of repair and rework tasks. The 500 g spool provides sufficient material for continuous use, reducing downtime and improving workstation efficiency.

Durability and environmental benefits

The SAC305 alloy has been engineered to reduce soldering tip wear – the low chemical aggressiveness of the flux minimizes degradation, extending tool life. The product is fully RoHS compliant and lead-free, meeting modern requirements for sustainable production and environmental protection.

The lead-free cored wire Sn96.5 Ag3.0 Cu0.5 with 3.5% ROL0 flux combines precise alloy composition, high metallurgical quality, and advanced usability. Its design ensures durable solder joints, aesthetic connections, and process stability in both industrial manufacturing and professional service environments.
