10 Pcs High Transparent and Bright Color Rosin for Welding Removing Oxidized Coating

Features: 100percent brand new and high quality. 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. When the iron head or the surface of the element 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. Rosin is the flux used in the welding of electronic circuits in which the oil from the trunk of a pine tree is melted into water at high temperature, and the dry knot becomes a massive solid (without a fixed melting point). In musical instruments, the strings used mainly for grinding musical instruments to make it play an astringent role.

As a result of metal surface and air contact will be formed after a layer of oxide film, the higher the temperature, the more serious oxidation.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. High purity super rosin, very transparent and bright color.
