Sn63Pb37 T5 solder powder

The Sn63Pb37 T5 solder powder is a classic eutectic solder powder that has been used in electronics production for decades. With its mixing ratio of 63 % tin (Sn) and 37 % lead (Pb), it offers a precisely defined melting point at 183 °C. The fine grain size according to T5 makes this soldering powder particularly suitable for applications where maximum precision is required.

Properties and advantages

• Eutectic alloy: Melts and solidifies at a uniform temperature, resulting in homogeneous solder joints.
• Fine grit (T5): Ideal for the production of Solder pasteswhich are used in high-resolution electronic processes such as fine-pitch and micro-BGA components.
• High process stability: Consistent quality ensures reproducible results in automated production processes.
• Wettability & flow behaviour: Excellent wetting properties ensure reliable and durable solder joints.
