BLE Rosin Welding Soldering Flux Paste High-purity For Phone 30g X Z0D5

100% new high quality This product is suitable for general welding of welding instruments instruments copper tin and iron. It is very helpful for the welding of circuit boards. When the surface of the soldering iron or components is oxidized it is not easy to tin and solder. Prevent oxidation. After it melts it floats on the surface of the solder to form an isolation layer thereby preventing oxidation of the soldered surface. Reduce the surface tension. Increase solder flow and help solder wet weldments. Color as shown Uses: High quality rosin which is very helpful for the welding of circuit boards. When the surface of the soldering iron or component is oxidized it is not easy to be tinned and soldered. After the rosin is applied with a soldering iron the oxidation can be quickly removed and the component becomes extremely easy to solder. Packing: 1*20g solid Rosin Paste
