Romeda 2 Jar Solder Flux, Flux for Soldering, Rosin Soldering Flux Paste for Lead-Free Electronics Soldering and Soldering DIY (1. 2oz/35g in a Jar.

Why use solder flux paste. Solder flux paste leaves a protective coating in the welding area to prevent corrosion. Improve efficiency and speed up the welding process, with less time to let the solder flow to where you need to provide more controllable and accurate welding. Our rosin soldering flux paste 1. Antioxidation and noncorrosive. 2. The boiling point is slightly higher than the melting point of the solder. As the solder melts, the solder begins to boil and absorb heat, thus keeping the temperature of the electronic components and PCB at this temperature. 3. Applicable to the mobile phone, PC board and other precision electronic chip level welding.
