The proper use of electric iron
Electric iron
1. Externally heated electric iron
Generally iron head, iron core, shell, handle, plugs and other parts of the composition. Tip installed in the iron core, the copper for good thermal conductivity of copper alloys as matrix material, the tip length can be adjusted (shorter tip, the higher the temperature of tip), and a chisel-type, conical tip, a round face, round, pointed cone-shaped and semi-circular groove such as different shapes to suit the requirements of different welding surface.
2. Heat electric iron
By the connecting rod, handle, spring clips, iron core, the tip (also known as copper head) of five parts. Iron core mounted inside the tip (heat fast, high thermal efficiency as high as 85%). Iron core wound with nickel-chromium resistance wire, the ceramic tube made of ordinary 20W soldering iron around their resistance 2.4kΩ, 35w soldering iron of its resistance1.6kΩ so. Commonly used in electric heat iron

Generally the greater the power soldering iron, heat the greater the higher the temperature of tip. Welding integrated circuits, printed circuit boards, CO0S 20W circuit generally used in electric heat iron. Use the soldering iron power is too large, easy to scorch the components (general, transistor junction temperature exceeds 200 °C, it will burn) and the printed wire off from the substrate: the power is too small to use a soldering iron, solder can not be fully melted , not out of the volatile flux, solder joint is not smooth, solid, easy to produce Weld, welding time is too long, will burn out the device, generally each spot within the 1.5 ~ 4 S.

3, other iron
1)constant temperature soldering iron
Electric soldering iron tip temperature within the temperature controller equipped with a magnet to control the power-on time, to achieve the purpose of constant temperature. In the welding temperature should not be too high, not too long welding time, the components should be selected temperature soldering iron, but it is high prices.
2)tin soldering iron absorption
Tin soldering iron absorption is the suction piston electric iron dissolved in tin and one desoldering tool with easy to use, flexible and applicable to a wide range of features. The downside is that you can only be removed to a spot welding.
3)gas soldering iron
One kind of use of liquefied petroleum gas, methane and other combustible gas burning heat of the soldering iron tip. For any inconvenience or unable to supply AC power supply situations.
