How much W is the best to use for welding circuit boards? How much is it?
Solder integrated circuit is best to use 20W, elephant resistor, capacitor class, use 30W. The integrated circuit will be damaged because of long soldering time and high temperature. Generally better electric iron on the 20 yuan.
30, 40, 50W electric iron refers only to the size of the power, generally used to see you for what it is if the welding circuit board, general household appliances can choose 20 25W, if the other components welding can choose 35 50W, if the welding pipes can choose 100W, if the welding cable head, water tank etc. you can choose 100 - 350W. The price is different according to the brand, capacity and variety. The average 25W electric iron is about 15 yuan.
The soldering circuit board usually uses the 30W electric soldering iron to be possible. The power of the electric iron is different, and the electric heating wire is also different from the iron core. If you don't know the size of the iron, you can measure its resistance, the smaller the resistance, the greater the power.
