I encountered two panel IC replacement during maintenance. It is difficult to remove IC from the circuit board. After opening, the circuit board is broken. It really breaks my mind. How do you tell my brother to disassemble it and choose the electric iron? Is there a good way? You can't use a needle
There is a special hot air gun, the volume is like a shoebox. When using, use hot air to blow IC solder parts, and gently pull IC down with tweezers. Note that the heating time can not be too long, the solder can melt, so as not to destroy components. If it is a single circuit board occasionally encounter this kind of situation, there are tips: with multiple filaments copper stick with rosin, ordinary electric iron melting solder, solder melting away immediately stained with it, can be repeated several times more than the net absorption. And you can use tin soldering iron.

The circuit board mainly consists of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc.. The common lamellar structures include single layer Layer (Single, PCB), double deck (Double, Layer, PCB) and multilayer (Multi, Layer, PCB) three kinds.
A thin copper wire is used to penetrate the IC pin. After the tin is melted, the copper wire is pulled out from under the pin
