Product Description

Sn63Pb37  Solder Paste (Syringe Packing and Bottle Packing) SMT

The Sn63Pb37 for PCB is a classic type of mid temperature tin lead solder paste. Its alloy comprises the 63% tin content and the 37% lead content. Its working temperature falls into the preheat temperature from 90ºC to 150ºC, the melting point of 183ºC, and the reflow temperature range from 190ºC to 100ºC. 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 63/37 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.

Applications
The Sn63Pb37 mid-temperature leaded solder paste is applicable for the LED circuit boards, diversified lighting fixtures, computer motherboards, phone motherboards, printed circuit boards, surface mount devices, as well as all kinds of high-precision circuit boards.

Features

• 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.
• 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.
• The original shape will not be changed after several hours of printing process. In addition, the surface mount assembly will not be affected.
• Beyond that, our Sn63Pb37 mid temperature tin lead solder paste for PCB can give favorable wetting property on the substrate made from different materials.
• Owing to its wonderful soldering performance, this product will not produce any tiny solder bead after the soldering process is completed.
