Flux is a chemical used in soldering, for the purpose of cleaning the surface of printed circuit boards. Cleaning is necessary to prevent oxidation of metal as oxidized metals create problems in bonding and soldering – which makes fluxing the most important activity in soldering. There are many soldering wires available which are cored with flux, so it becomes unnecessary to flux before soldering when cored solder wires are used. However, when there is no flux-cored wire, cleaning surfaces is very important. In this blog, we will discuss the effectiveness of liquid soldering flux in solder metals.
There are many kinds of flux available in the market. The two major categories are rosins and water soluble fluxes. Both fluxes need to be cleaned from the board after application. Rosins require a solvent to get washed, while water-soluble fluxes can be cleaned with water. Liquid soldering flux is majorly used in surface mount soldering processes. It is a precision flux which works well with small components. It can be used with needles, syringes, orflux pens for application onto surfaces, facilitating accuracy in application. This is a necessary requisite which ensures there is no residue after the flux has done its work. Liquid solder has one more colossal benefit over its counterparts – it spreads well. If you are mounting components with high difficulty level of soldering, using a liquid flux will allow you to achieve more effective cleaning as compared to other forms.
Liquid soldering flux is not recommended for through-hole soldering, though, for the practical difficulty of it.
