How to weld electronic components

In the production of electronic components, connections to welding. The welding quality of making quality greatly. So, studying the electric to manufacture technology, must grasp the good welding welding technology, basic skills.
A, welding tools
(a) the electric iron. Electric soldering iron is the most commonly used welding tool. We use20WInternal heated electric soldering iron.The new iron before use, electricity heat, with rosin with tip edge contact solder wire, the iron plated with a layer of tin head evenly. In so doing, can facilitate welding and prevent surface oxidation of the iron head. The old iron head such as severe oxidation blackening, available steel put to the surface oxide, to expose the metal luster, re tinning, can use.Electric soldering iron to use220VThe AC power, used to Caution. Should do the following:
　　1, Electric soldering iron plug. The best use of the three pole plug. To make the case properly grounded.
　　2. before use, should check the power plug, power line is damaged. And check whether the loosening of the soldering iron head.
　　3. electric iron in use, not hard hit. To prevent falling. Soldering iron head solder is excessive, usable cloth wipe. Do not throw, in order to avoid the scald others.
　　4. in the process of welding, soldering iron can not be everywhere. No welding, should be put on the iron frame. Note the power line can not be resting on the soldering iron head, to prevent burning insulation accidents.
　　5, After use, should be promptly cut off the power, unplug the power plug. After cooling, and then the electric iron recovery toolbox.

(b), the solder and flux
When welding, also need to solder and flux.
　　1Tin solder. Soldering of electronic components, is generally used with rosin core solder wire. The solder wire, low melting point, but also contains rosin flux, is extremely easy to use.
　2.Flux. Commonly used flux is rosin or rosin (rosin dissolve in alcohol). The use of flux, can help to remove the metal oxide surface, suitable for welding, and can protect the iron head. Larger components or welding wire, also can use solder paste. But it has certain corrosion, welding should be promptly removed.
