In today's electronics manufacturing industry, the demand for lead-free solutions has never been higher. As global regulations tighten and environmental concerns grow, it's essential to choose materials that meet safety standards without compromising on performance. Our Lead-Free Tin Paste Sn96.5Ag3Cu0.5 SAC305, available in both T3 and T4 powder sizes, is a top-tier solution that addresses these needs head-on. The lead free tin paste is a mixture of tin silver powders with rosin flux and some binders. It's generally used for assembly of PCB and electronics products by using surface mount technology.
1. Environmentally Friendly and Compliant
Our tin paste Sn96.5Ag3Cu0.5 is a lead-free alloy that aligns with RoHS and REACH regulations, making it an ideal choice for manufacturers looking to comply with global environmental standards. By opting for this lead-free tin paste SAC305, you contribute to a safer, healthier planet while maintaining a high level of product quality.
2. Superior Alloy Composition:
The Sn96.5Ag3Cu0.5 SAC305 alloy composition—comprising 96.5% Tin (Sn), 3% Silver (Ag), and 0.5% Copper (Cu)—offers an exceptional balance of melting point, mechanical strength, and soldering reliability. This combination ensures excellent wetting properties, resulting in smooth and uniform solder joints. The presence of silver and copper in tin paste SAC305 also enhances the thermal fatigue resistance, making it suitable for a variety of high-reliability applications.
Our SAC305 tin paste is available in two powder sizes: T3 and T4. Each has unique properties that make it suitable for specific production processes and requirements.
T3 Powder Size:
Versatility at Its Best: The lead free tin paste with T3 powder size is ideal for a wide range of applications, from manual soldering to automated processes like stencil printing. T3 powder size is 25 to 45μm. It offers a balance between viscosity and flow, making it easy to apply while ensuring excellent coverage.
Suitable for Larger Components: With slightly larger particle sizes, the tin paste with T3 powder size is better suited for assembling larger components. It provides robust solder joints that can handle the mechanical stresses associated with such parts, ensuring long-term reliability.
T4 Powder Size:
Precision for Fine-Pitch Applications: The lead free tin paste with T4 powder size is perfect for fine-pitch applications, where precision is key. T3 powder size is 20 to 38μm. Its smaller particle size allows for finer print resolution, making it ideal for applications that require high levels of detail, such as circuit boards with closely spaced components.
Smooth Printing Performance: The tin paste with T4 powder size delivers smooth and consistent stencil printing, reducing the risk of clogging and bridging. This makes it particularly valuable for high-volume production environments where efficiency and yield are critical.
1. Consistent Print Quality: Whether you choose T3 or T4 powder sizes, our SAC305 tin paste ensures excellent printing performance. Its stable viscosity and tack time allow for easy handling, reducing defects such as slumping or excessive voiding.
2. Reliable Joint Strength: The Sn96.5Ag3Cu0.5 alloy's superior mechanical properties ensure strong and durable solder joints, capable of withstanding thermal cycles and mechanical stress. This is crucial for products that will experience temperature variations or physical handling.
3. High Yield with Low Defects: Our Sn96.5Ag3Cu0.5 tin paste's optimized formulation minimizes common issues like solder balling and bridging, ensuring high first-pass yield rates. This means fewer rework requirements, saving time and cost for manufacturers.
4. Enhanced Wetting and Spread-ability: Thanks to its refined alloy composition, the SAC305 lead free tin paste exhibits excellent wetting properties, allowing it to spread evenly across pad surfaces. This results in smoother solder joints and better overall appearance, which is especially important in high-quality electronics.
The versatility of our Lead-Free Tin Paste Sn96.5Ag3Cu0.5 SAC305 makes it suitable for various PCB SMT applications, including:
Consumer Electronics: Ideal for smartphones, tablets, and other small devices where fine-pitch assembly is critical.
Automotive Electronics: Perfect for high-reliability environments where thermal stability and robust joint strength are required.
Medical Devices: Suitable for devices that require compliance with stringent safety and environmental standards.
Telecommunications Equipment: Ensures reliable performance in devices where signal integrity and electrical connections are vital.
