The NOS-100 SAC 305 solder bar is an industry-standard, silver-bearing lead-free alloy (Sn96.5/Ag3.0/Cu0.5). It is designed for high-reliability wave soldering.

Key Features of the SAC 305 Solder Bar

• Sn96.5/Ag3.0/Cu0.5 alloy
• Melts at about 217°C
• Perfect for wave soldering

Strong, Reliable Joints

This 1kg extruded bar gives excellent thermal fatigue resistance and mechanical strength. As a result, it is a preferred choice for automotive, aerospace and medical electronics.

A Wider Process Window

The 3% silver content lowers the melting point to about 217°C compared with other lead-free alloys. So you get a broader process window and less thermal stress on sensitive parts.

Excellent Hole Fill

High wetting performance gives excellent hole fill. In addition, it keeps bridging to a minimum on high-density boards.

Why Choose This SAC 305 Solder Bar?

SAC 305 helps manufacturers achieve consistent, long-lasting joints that exceed IPC Class 3 requirements. For example, it suits any line where joint integrity is critical.

Therefore, you get high reliability while staying fully compliant with environmental rules in global markets.

Where It Works Best

This alloy is made for wave soldering pots. For example, it suits through-hole assemblies on automotive, aerospace and medical boards, where every joint must hold up to vibration and temperature change.

Because each bar is extruded and weighs 1kg, it is also simple to handle and top up. As a result, operators can keep the solder level steady during a shift.

Moving to Lead-Free

SAC alloys are the most common choice for lead-free wave soldering. So if you are moving away from leaded solder, this bar gives you a proven, widely used starting point.
