Sn100 T4 soldering powder

Sn100 T4 soldering powder is an almost pure Tin solder with over 99.9 % Tin. It has a melting point of approx. 232 °C and is particularly suitable for applications where no other alloying metals are required. The T4 grit (20-38 µm) enables finer stencil printing and precise paste rheology - ideal for fine-pitch designs and high-resolution SMT processes.

Properties and advantages

• Nearly pure tin (Sn 99.9 %): For defined, lead-free soldering processes without additional alloying elements.
• Fine T4 grit: Supports high-density layouts, micro-BGA and fine-pitch structures.
• Stable melting point (~232 °C): Ensures reliable, reproducible processing.
• Silver and copper free: Cost-efficient alternative to more complex alloys.
• Lead-free & RoHS compliant: Sustainable solution for modern electronics production.
