Hilitand 10pcs Solid Rosin Paste Soldering Flux for Welding Removing Oxidized Coating

Features: The oxide film prevents the liquid solder from wetting the metal, just as the oil on the glass prevents the water from wetting it. Flux is a special material used to remove oxide film, also known as flux. Specification: Material:Rosin Package List: 10*Rosin Note: As different computers display colors differently, the color of the actual item may vary slightly from the images.

• high-grade: It has high purity super rosin, it's very transparent and bright color.
• USAGE: This product is suitable for welding of general instrument, instrument, copper, tin, iron and so on. It is very helpful for the welding of circuit board.
• NOTE: As a result of metal and air will be formed after a layer of oxide film, the higher the temperature, the more serious oxidation.
• FUNCTION: Rosin is the flux used in the welding of electronic circuits in which the oil from the trunk of a pine tree is into water at high temperature, and the dry knot becomes a massive solid (without a fixed melting point).
• GOOD WELD: When the iron head or the of the is oxidized, it is not easy to be tin and welded. The rosin makes the components very easy to weld, and the effect is obvious.
