Product Description
Lead Free Solder Bar Sn99.3Cu0.7
The saying of Lead free solder bar is comparing to traditional lead containing solder bar. At the very beginning, Tin Lead alloy were the major solder alloys for long time, but gradually when lead was proven to be not good for human health and considered as heavy metal, starting from Europe related regulations on electronic industry was reformed and ROHS regulation was published, in some applictions leaded solders are fully banned. Thus replacement of the leaded solders -- the lead free solders were brought to be market.
At the moment, in the market there're 3 major types or solder alloys: Sn96.5Ag3.0Cu0.5 (SAC305), Sn99Ag0.3Cu0.7 (SAC0307), Sn99.3Cu0.7 (SACX07). SAC305 contains 3.0% silver and have the best soldering property, suitable for high end applications. SAC0307 has a low silver at 0.3% only but still have quite good soldering property. SACX07 contains no silver, just alloy of tin and copper, but this alloy has very good cost-efficiency ratio.
Property of Lead Free Solder Bar Sn99.3Cu0.7
Sn99.3Cu0.7 solder bar has the highest melting point among the 3 major lead free solder bars, at temperature of 227℃, comparing to SAC305 is at 217℃, about 10℃ higher. In a certain sense, in most general applications, Sn99.3Cu0.7 (SACX07) can be used to replace the expensive SAC305, because the working termperature is not much difference.
If you're looking at to use SACX07 Sn99.3Cu0.7 to replace the traditional leaded solder bar Sn63Pb37, make sure you're noticed about the big difference in melting point, because the leaded alloy's melting point is only 183℃, about 45℃ lower than SACX07 bar solder. Make sure the working temperature of this solder alloy fits into your applications, and use the right temperature of solder pot.
Very budget price of lead free solder bar Sn99.3Cu0.7, because it doesn't contain the precious metal silver comparing to SAC305, thus cost wise, it's just about 50% price of SAC305 bar solder.
Other information of Lead Free Solder Bar Sn99.3Cu0.7
