The role of rosin in the use of white HAKKO soldering iron tips

White light soldering iron head before welding to point rosin, a lot of friends must also often do this, white light soldering iron head using rosin in the end what is the role of?

First of all: what is rosin? Rosin is commonly known, it is actually a flux. Flux rosin belongs to the fat rosin in a class of products, mainly yellow and yellowish two kinds, are rosin deep processing products, can be dissolved in alcohol solvent.


Second: rosin in the role of soldering is:

First: the soldering iron tip does not stain the tin, stained rosin, easy to melt the tin and stained in the iron tip.

Second: tin wire is made into a very thin, because it is easy to melt, dip rosin, easy to melt the thin wire into a rounded full droplet shape, rather than running around

Third: Solder drops directly on the solder joints, solder joints for cleaning or oxygenation, if it is easy to contact is not firm, a touch off, add rosin is conducive to the removal of the negative effects of oxidation, is the solder more firmly


Fourth: no solder, the soldering iron from the solder joints when removed easily solder adhesion, resulting in unsightly solder joints


From the above points can see the role of white soldering iron using rosin, in the soldering process has a very important role, so we want to have a beautiful soldering products, rosin is indispensable!
