solder paste Sn99Ag0.3Cu0.7 instructions:
Our Sn99Ag0.3Cu0.7 OB-SP307 lead free silver solder paste adopts the alloy which is formed by the 99% tin, the 0.3% silver, and the 0.7% copper. This product is desirable for the reflow soldering process which has relatively high demand. Its working temperature can be divided into three types. The preheat temperature varies from 140 degrees Celsius to 190 degrees Celsius. The melting temperature about 250 degrees Celsius, and the reflow temperature ranges from 250 degrees Celsius to 240 degrees Celsius.
