I encountered in the repair process two panel IC replacement. It is difficult to remove the circuit board IC. Disconnect the circuit board is broken, really let me headache. Trouble you tell the younger brother how to dismantle, choose the kind of electric iron good? Is there a good way? Not with a needle
The circuit board is mainly composed of the pad, the hole, the mounting hole, the wire, the components, the connector, the filling, the electrical boundary and so on. Common board structure includes single layer board (Single Layer PCB), double deck (Double Layer PCB) and multilayer board (Multi Layer PCB).
Circuit board, also known as circuit board, PCB board, aluminum substrate, high frequency board, ultra-thin circuit board, ultra-thin circuit board, printing (copper etching technology) circuit board, etc..
There is a dedicated hot air gun, volume like a shoebox. When used with hot air blowing IC solder parts, gently remove the IC tweezers. Note that the heating time can not be too long, the solder can be melted, 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 a tin soldering iron.
