1. Introduction:   

The Sn*3Pb*7 for PCB is a classic type of mid temperature tin lead solder paste. Its alloy comprises the *3% tin content and the *7% lead content. Its working temperature falls into the preheat temperature from *0℃ to **0℃, the melting point of **3℃, and the reflow temperature range from **0℃ to **0℃. This product is suitable for the highly demanding reflow-soldering process.



As one of the leaded series products developed by our company, the solder paste *3/*7 can offer extremely good soldering effect. It has been exported to India, Russia, and other countries. Moreover, we are looking for agents around the world.



 

1. With superb fluidity and nice soldering effect, our product can accomplish the exquisite printing of the pad, the separation distance of which can be only 0.3mm.

2.There are very few changes of viscosity during the continuous printing process. The viscosity will not be altered, even after 8 hours of operation of the steel mesh. Moreover, our product can still maintain the favorable and continuous printing effect.

3.The original shape will not be changed after several hours of printing process. In addition, the surface mount assembly will not be affected.

4.Beyond that, our Sn*3Pb*7 mid temperature tin lead solder paste for PCB can give favorable wetting property on the substrate made from different materials.

5. Owing to its wonderful soldering performance, this product will not produce any tiny solder bead after the soldering process is completed.
