Our Sn30Pb70 tin lead solder wire and solder bar pertains to a kind of high-temperature leaded solder wire with its melting temperature of 225 degrees Celsius and the operating temperature of 280 degrees Celsius. Its alloy is composed of the 30% tin content and the 70% lead content, and its diameter ranges from 0.35mm to 3.0mm.
This series of rosin-cored solder wire adopts the newest type of activated rosin flux, which is produced in use of the most advanced automated equipment. Then, it can be adapted to the complexity and high precision of the development of the electronics industry.
The Sn30Pb70 tin lead solder wire and solder bar is provided with uniform surface, extremely high purity, superb fluidity, wonderful wetting property, and a rare occurrence of oxidizing slag. It is fit for the manual welding process which has high demand.
Furthermore, this product is highly resistant to oxidation. It can provide the mirror-like surface, short wetting time, and relatively high expansion rate at below 300 degrees Celsius. Its solder joint is glossy and nice, which allows our product to be desirable for the spot welding of PCB parts.
