Integrated circuit overhaul is a huge project, because the integrated circuit has many pins and is very dense, which is very difficult to disassemble, and sometimes even damages the integrated circuit and the circuit board. The following several effective integrated circuit disassembly methods are available for your reference.
1. Multi-strand copper wire suction disassembly method
It is to use a multi-strand copper core plastic wire to remove the plastic outer skin and use a multi-strand copper wire (a short wire head can be used). Before use, apply multiple strands of copper wire to the rosin alcohol solution. After the soldering iron is heated, place the strands of copper wire on the pins of the manifold to heat the pins. The solder on the pins will be absorbed by the copper wires. The upper solder can be cut off and the solder on the pins can be removed by repeating it several times. Braided wires in the shielded wire can also be used if available. Simply suck the solder and use a tweezers or a small “one†screwdriver to gently remove it. The integrated block can be removed.
2, suction tin suction disassembly method
The use of a soldering tin to disassemble the integrated block is a commonly used professional method. The tool is a common suction and soldering soldering iron with a power of more than 35W. When disassembling the integrated block, just put the heated dual-purpose soldering iron tip on the pin of the integrated block to be disassembled, and after the solder is melted, the tin is sucked into the fine tin, and the solder of all the pins is sucked and the integrated block is Can be taken off.
3, increase the solder melting disassembly method
This method is an easy way to add some solder to the pins of the integrated block to be removed, so that the solder joints of each column of pins are connected, so as to facilitate heat transfer and easy disassembly. When disassembling, use a soldering iron to heat a column of pins with a sharp tweezers or a small “one†screwdriver. The two columns of pins are rotated and heated until they are removed. In general, each column of pins can be removed by heating twice.
4, medical hollow needle removal method
Take a few medical needles 8 to 12 hollow needles. It is advisable to use the inner tip of the needle just to fit the manifold block pin. When disassembling, use a soldering iron to melt the solder on the lead. Use a needle to cover the pin in time, then remove the soldering iron and rotate the needle. After the solder solidifies, pull out the needle. This pin is completely separated from the printed board. Once all the pins have been done this way, the integrated block can be easily removed.
5, electric iron brush with disassembly method
This method is simple and easy, as long as there is a soldering iron and a small brush. When disassembling the integrated block, first heat the soldering iron. After the soldering temperature is reached, the solder on the lead is melted, and the melted brush is swept away by the brush. This allows the pins of the manifold to be separated from the printed board. The method can be performed separately or in separate steps. Finally, use a sharp tweezers or a small "one" screwdriver to pry the integrated block.
