Product Features

Near Eutectic Composition

The SAC0307 solder wire, with its Sn99.3Ag0.3Cu0.7 composition, closely approximates a eutectic mixture, providing a relatively narrow melting range. This characteristic ensures a smooth transition from solid to liquid at a consistent temperature, facilitating precise soldering operations.

Enhanced Electrical Conductivity
With a high tin content and a touch of silver, the SAC0307 offers improved electrical conductivity compared to many standard lead-free solders. This makes it highly effective for electrical and electronic applications that demand excellent signal integrity.

Lead-Free and Eco-Friendly
Compliant with environmental directives such as RoHS, the SAC0307 solder wire is completely lead-free, which reduces harmful emissions during soldering and lowers the environmental footprint. Its adoption supports sustainable manufacturing practices.

Moderate Melting Point
The melting point of SAC0307 is around 217ºC to 227ºC, which is ideal for a broad spectrum of soldering applications. This moderate range helps prevent damage to sensitive components while still accommodating a wide variety of soldering needs.

Cost Efficiency
Although lead-free alternatives tend to be more costly, SAC0307 remains a cost-effective solution for achieving compliance with environmental standards without a significant increase in manufacturing expenses. Its price point is appealing for both small projects and large-scale production.

Applications of Lead-Free Solder Wire SAC0307 (Sn99.3Ag0.3Cu0.7):
Consumer Electronics: Ideal for assembling and repairing consumer electronics such as smartphones, tablets, and televisions, where reliable electrical conductivity is crucial.

High-Performance Devices: Suitable for devices that require high performance and reliability, including medical equipment and aerospace components, where the enhanced properties of SAC0307 can be fully utilized.

Telecommunications: In the telecommunications sector, where maintaining signal integrity is paramount, SAC0307 provides dependable soldering solutions for both infrastructure and device manufacturing.
