A-pine rosin Rosin is consisted in conifer resin and produced from oleoresin. It's a fragile, glassy, amorphous substance that can be from dark red to light yellow, when melted it smells like pine resin. Besides different produced types rosin has been widely spread as neutral flux for soldering and tin coating in electrical and radio engineering industries. Rosin is produces in solid, liquid and gel states for convenience when using and putting it on a solder. For example, solid rosin is easy to use for soldering and tin-coating of wires and different radio components outputs. In order to solder in hard-to-reach places rosin is powdered and dissolved in ethylic or boric alcohol turning it into alcohol resin flux. It's easy to put on contacts with a brush and solder not only small components on a printed board, for example, but also tin-coat rather big copper surfaces. Gel rosin has the same properties as those of standard solid rosin. But in this case it's possible to make precise doses and put very quickly even on a great number of solder joints because gel holds on different contacts and electronic components outputs very well. It should be noticed that rosin acts as a base of most neutral fluxes for low-temperature soldering. And it has been considered as one of the best fluxes for preparing surfaces before soldering and increasing wettability and flux flow-out by now. Thus, using rosin for soldering you will always sure about reliability and long-life of even the most important joints of communications electronics equipment.
