Sn99Ag0.3Cu0.7 tin wire, often called SAC0307, is a commonly used soldering material, especially suitable for PCB (Printed Circuit Board) soldering. This tin wire alloy is lead free. This article will introduce in detail the advantages of SAC0307 tin wire in PCB soldering, as well as its characteristics and advantages compared with other tin wire.
Composition: SAC0307 lead free tin wire Sn99Ag0.3Cu0.7 is composed of 99% tin (Sn), 0.3% silver (Ag) and 0.7% copper (Cu). The design of this ratio gives the tin wire good soldering properties and mechanical strength. It is one of the most widely used lead free tin wire alloy.
Low melting point: tin wire Sn99Ag0.3Cu0.7 has a relatively low melting point of approximately 217-220°C, making it suitable for surface mount technology (SMT) and manual soldering processes in PCB assembly.
Good wettability: SAC0307 tin wire has good wettability and can quickly form a uniform wetting layer during the soldering process to ensure the stability and reliability of the soldering connection.
High strength: Sn99Ag0.3Cu0.7 tin wire containing silver and copper has high mechanical strength and corrosion resistance, and the welded connection has better durability and stability.
Good reliability: SAC0307 tin wire soldering connection has high strength and stability, can meet the use requirements of PCB under various environmental conditions, and improves the reliability of soldering connection.
Suitable for RoHS standards: this tin wire complies with RoHS (Restriction of the Use of Certain Hazardous Substances Directive) standards, does not contain lead, complies with environmental protection requirements, and is suitable for various applications with strict environmental protection requirements.
Good processability: this tin wire is easy to process and use, and is suitable for efficient production on automated production lines, improving production efficiency.
Excellent electrical properties: SAC0307 lead free tin wire has good electrical conductivity and resistivity and will not negatively affect the electrical properties of the PCB.
Compared with Sn63Pb37 tin wire and Sn60Pb40 tin wire: SAC0307 tin wire is lead-free and meets environmental protection requirements, while Sn60Pb40 tin wire contains lead and does not meet environmental protection requirements. In addition, Sn99Ag0.3Cu0.7 lead free tin wire has higher mechanical strength and corrosion resistance.
In conclusion
As a lead-free soldering material, SAC0307 tin wire has obvious advantages in PCB soldering. Its good soldering performance, mechanical strength and environmental protection make it one of the preferred materials in PCB manufacturing and assembly. Compared with other tin wires, SAC0307 tin wire has a higher level of reliability, environmental protection and soldering performance, meeting the needs of the modern electronics industry for high-quality soldering connections.
