Solder paste - paste viscous body, main component metal powder, rosin, organic acid, thixotropic agent, active agent. Soldering for SMT automatic placement process, an upgraded alternative to flux and soldering processes, high degree of automation, high precision of soldering

Although solder paste and rosin all have the effect of soldering, their nature is completely different. Solder paste is an upgraded alternative to rosin and soldering processes. No matter how rosin and solder paste have their advantages and disadvantages, after we use it slowly, we will find a solder material that is most suitable for our own use.

Rosin is refined from the secretions of pine trees. It is non-conductive in the case of dryness and is not corrosive to metal materials such as circuit boards. It is often used as a soldering aid for soldering tin and copper components on circuit boards.

The solder paste is a synthetic flux that contains a certain amount of acidic substances and has a certain corrosive effect on the metal. It is also electrically conductive, but because the solder paste has a better soldering effect than rosin, it is used as a flux for tin plating of devices such as iron.
