Product Introduction
The lead electrode produced by our company is made of pure tin ingots and high purity pure tin ingots containing tin ≥99.95%, as well as electrolytic pure lead metal raw materials. Under strict quality control conditions, after the inspection of our senior engineers using German direct reading spectrometer, the solder bar has the following outstanding characteristics:
The first high purity materials: We use high purity raw materials, including pure tin ingots and electrolytic pure lead metal, to ensure that the purity of the solder bar is extremely high, reducing the content of oxidation and impurities.
Second full tin: The tinness of the solder bar is very full, ensuring that the tin metal is evenly coated on the welding surface when welding, forming a strong solder joint.
Third, no impurities: Through high-tech fully automated production equipment and vacuum deaeration treatment, the degree of oxidation and the content of metal and non-metal impurities are effectively controlled to ensure the purity of the solder strip.
Fourth, quality testing is strict: our senior engineers use German direct reading spectrometers for precise testing of solder bars to ensure high reliability of product quality.

Product Features
The solder joint is full without collapse
High purity tin
Solder shine
Uniform solder joint
Good weldability
Good antioxidant
Tinning fast
Low tin slag
Under the same process conditions, the chain speed is accelerated from 70cm/min to 90cm/min, the fluidity of the solder is improved, the soaking time is shortened, and the temperature of the tin furnace can be kept low, thereby reducing the problem of tin slag and metal elements (such as copper chromium), which helps to improve the quality and efficiency of the welding.
Product Advantage
Using high quality and high purity tin ingot raw materials, less tin oxide slag, good electrical and thermal conductivity.
Less impurities, good wettability, strong expansion ability, minimize the phenomenon of pulling the tip and overseas Chinese union.
The lead content of different models is clearly marked, and sellers can customize according to their own needs.
