]]> The 62S SMQ is a premium, ultra-high purity solder bar specifically engineered for modern electronic assembly. Manufactured from high-grade refined virgin metals, this tin-silver-lead delivers exceptional performance and batch consistency in all assembly situations, while ensuring high yields and low production costs.

Thanks to a special anti-drossing treatment during manufacture, E-Qual solders show a marked reduction in dross formation compared to untreated materials. This results in cleaner, well-formed joints, a reduction in icicling and bridging, and ultimately, reduced product usage and machine maintenance.

The consistent quality control procedures ensure every bar meets or exceeds all internationally recognised standards. We also offer a free regular solder analysis service for customers to check bath contamination levels and ensure quality is maintained within strict operating parameters.

Key Features and Benefits of 62S SMQ Solder

Low SAC Type Y (SAC0307) FAQ

How does SAC0307 compare to SAC305 in terms of cost and performance? +

SAC0307 contains significantly less silver (0.3% vs 3.0%), making it a much more cost-effective alternative to SAC305. While it offers a slightly higher melting range, its wetting performance is comparable to SAC305 in most standard wave soldering applications.

What is the optimum operating temperature for a LowSAC bath? +

The recommended operating temperature is 265°C ± 5°C. Operating at this temperature ensures excellent through-hole penetration and fast wetting while maintaining the stability of the alloy’s fluidity during dynamic wave soldering.

How should I manage copper build-up in the solder pot? +

Lead-free alloys naturally dissolve copper from PCBs. To keep copper levels within the recommended 0.6%–0.8% range, use LowSAC Type Ye copper-free top-up alloy. Regular bath analysis is essential to determine when a partial drain or top-up is required.

Is LowSAC Type Y compatible with my current flux? +

Yes, this alloy is designed for high compatibility. It works effectively with low-solids, no-clean, and VOC-free flux formulations. Always refer to your flux manufacturer’s data sheet to ensure the pre-heat and contact times are optimized for a 228°C liquidus.

Why does SAC alloy joints look dull compared to tin/lead? +

This is a natural characteristic of lead-free SAC alloys. Due to the inherent grain structure and cooling rates, joints will appear more matte or “dull” than traditional SnPb joints. This does not indicate a sub-standard or weak connection; it is purely a visual difference.
