I want to change the circuit board inside the element, want to use the electric iron melt element feet when welding off, is not mixed with other high-temperature material??? What am I going to do?Also have their own welding, it is not easy to weld the defective products, burn out the circuit board?The answer is quiet and Jane. Here you are
I think you should use the electric iron to touch the solder. It's not the result of the welding. It seems really easy to be defective. But be careful, try it, it's not impossible to succeed
The basic principle of welding is to make use of the physical characteristics of tin alloys. The general requirements for lead-free solder tin soldering temperature reaches 210 degrees to 180 degrees, the two temperature are two kinds of solder melting point value.In addition, if the solder joint itself has a thicker oxide layer, there will be poor heat conduction, the temperature of the soldering iron is difficult to pass to the solder joint.Mastering these concepts is very helpful in welding.
30W well, the power assembly burns out the original. I've met too. But only once is the NOKIA CA-100C boost circuit, smd. I'm just removing a patch resistor to adjust the voltage. But it just doesn't work. The last direct use needle nose pliers. It seems to be a good heat dissipation. The heat on the resistor is rapidly dispersed. You can't solder until you reach the melting point
