Solid lead free win wire is a tin wire without flux or rosin in the middle of the tin wire. It is a special kind of tin wire, which is generally used in automatic soldering machines. Solid core tin wire, the advantage of solid core tin wire is that the smoke is small or even no smoke, the disadvantage is that the tinning efficiency is poor, the industry is different, and the requirements for soldering are also different. The composition of the metal is different, and the use is also different. Some product industries must use solid tin wire, and some products must use rosin tin wire. Rosin can greatly improve the fluidity of liquid tin, and can also prevent the oxidation of the metal to be soldered and form an oxide film. Generally speaking, it is easier to stick than solid ones. If you are soldering an add-in to an off-the-shelf printed circuit board, since most boards are coated with flux, just use solid solder wire. Using solid core tin wire after applying flux is actually the same as rosin-containing tin wire, but it is used separately.

Tin wire is rolled up one by one,and the weight is 800g/roll,1000g/roll, etc. Or according to customer requirements,contactbusiness personnel for specific prices,subject to real-timequotations.
