Function: Improve the welding process of electronic components through the use of anti-oxidation flux. Facilitate solder flow, ensure easy tinning, direct welding, and create robust welds. Feature: Establish high-intensity connections with excellent immersion, insulation and welding properties, resulting in a smooth welding surface. User Guidance: Before welding, clean the surface of the object, apply the paste to soldering metals such as copper, iron and tin, and then use the soldering iron to melt the tin at the solder point. Soldering Paste: Solder paste is suitable for welding electronic components, providing a combination of ease, durability, quick cleaning and effective insulation. Application: This flux for welding is well suited for welding instruments, gauges, gold, copper, iron, tin, and other metals. It is widely used in phone PCB repair, SMD component soldering, appliance repairs, and more. › See more product details Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
