Is a high power soldering iron better or a low power one?
There is no such thing as more power or less power!
There are various kinds of power of electric iron, the smaller ones are 15 watts, 20 watts, the larger ones are 200 watts, 300 watts, and there are also pistol type 500 watts. In the welding work, must be based on the welding object to determine the power of the iron, and sometimes also according to the climate season (winter, summer) to choose the power of the electric complex iron. Welding electronic components, with 15 watts to 20 watts is good, with 500 watts, a soldering iron down, is a black hole, of course, not good.
Power selection is not appropriate, mainly depends on the flow of solder melting, the process does not exceed three seconds. Too long will damage the electronic components, too short welding is not secure, solder joints are not smooth.
General welding resistors, capacitors, transistors, integrated blocks and other small foot components should choose 20 watts of power soldering iron, winter increase a gear, choose 25 watts. Welding heatsinks, transformers, shields and other large foot devices, or grounding large areas of copper-plated board with 35 to 40 watts. Therefore, according to the object of welding, the appropriate choice of the power of the soldering iron, there is no good power or power is good.
Soldering iron is electronic production and electrical maintenance of the necessary tools, the main purpose is to weld components and wires, according to the mechanical structure can be divided into internal and external hot soldering iron, according to the function can be divided into no tin soldering iron and suction tin soldering iron, according to the use of different types of soldering iron is divided into high-power soldering iron and low-power soldering iron.
