Solder Rosin High quaility Carton Rosin Soldering Iron Soft Welding Fluxes Repair Tools
High-quality rosin is very helpful for the soldering of circuit boards. When the soldering iron tip or the surface of the component is oxidized, it is not easy to tin and solder. After the soldering iron is soaked with rosin, the oxidation can be quickly removed, making the component extremely easy to solder.
Rosin use knowledge:
1. With rosin, the solder joints will be more beautiful, and the solder joints with solder paste will be black.
2. It is best to solder the circuit board with rosin, because rosin is a flux. But it can’t be too much, just a little bit. Those who are new to repair will not be able to grasp the measure. Frequent soldering is enough. The tin point can not be too large or too small. Look at the solder joints on the circuit board. Now the boards are all machine-welded, some of them are repaired manually, and the repairing places are where the current is relatively high and the voltage is relatively high. Please look at old-fashioned electronic products or old-fashioned black-and-white TV sets with manual soldering. Not good-looking, but sturdy. There is no open soldering. In the late 1980s, basically machine welding, also called wave soldering, was fast and good, but there were more welding in places with higher currents. Solder paste is only used when soldering iron parts that are difficult to tin. It is corrosive. Generally, only rosin is used. The role of rosin is to precipitate oxides in the solder, protect the solder from oxidation, and increase the fluidity of the solder.
3. Electronic components are usually tinned well. If they are rusty, they must be scratched first, and then put on the rosin and ironed with a soldering iron, and then tinned. After the circuit board is scratched, you can directly plug in the tinned components and solder them with rosin core solder wire. Remove the soldering iron before the rosin evaporates. If the solder is sticky, add some rosin. Do not move the components before the solder solidifies.
