Shenzhen Circuit Board Factory: How to disassemble the integrated circuit on the circuit board

In circuit maintenance, it is often necessary to remove the IC from the printed circuit board. Because the IC pins are many and dense, it is difficult to remove, and sometimes it will damage the IC and circuit board. Here, Shenzhen Circuit board factory Xiaobian found several effective integrated circuit disassembly methods for your reference.


1. Tin absorber tin suction disassembly method

Use a tin absorber to disassemble the integrated block, which is a common professional method. The tool used is an ordinary suction and welding dual-purpose electric iron, with a power of more than 35W. When removing the integrated block, just place the heated dual-purpose electric soldering iron head on the pin of the integrated block to be removed. After the solder joint is melted and sucked into the fine tin, the integrated block can be removed after the solder of all the pins are sucked.


2. Medical hollow needle disassembly method

Take a couple of medical 8 to 12 hollow needles. When used, the inner diameter of the needle is just over the pin of the integrated block. When disassembling, melt the pin solder with the soldering iron, cover the pin with the needle in time, then remove the soldering iron and rotate the needle, and pull out the needle after the solder solidifies. This allows the pin to be completely separated from the printed board. After all the pins have been done this way, the block can be easily removed.

Keyou Circuit is a professional production of high precision single panel/double panel/multilayer circuit board, smart home circuit board, car circuit board, dashcam,COB power supply, computer motherboard,LED aluminum substrate, aluminum circuit board, thermoelectric separation copper substrate, etc., quality assurance, delivery on time, to sales as one of the high-tech enterprises.


3. Electric soldering iron brush with disassembly method

This method is simple and easy to do, as long as you have an electric iron and a small brush. When disassembling the integrated block, heat the electric iron first. When the soldering tin on the pin is melted at the melting temperature, use a small brush to sweep away the melted solder. This separates the pin of the block from the printed board. The method can be carried out separately or separately. Finally, pry off the block with pointed tweezers or a small "one" flathead screwdriver.


4. Add solder melting disassembly method

This method is a convenient method. As long as some solder is added to the pins of the integrated block to be dismantled, the solder joints of each column of pins are connected, so as to facilitate heat transfer and facilitate disassembly. When disassembling, each row of pins heated by electric iron should be pry with pointed tweezers or small "one" flat-head screwdriver. The two rows of pins should be heated alternately until removed. Normally, each column of pins can be removed after heating twice.


5. Multi-strand copper wire tin absorption disassembly method

Is the use of multiple strands of copper core plastic wire, remove the plastic skin, the use of multiple strands of copper core wire (short wire can be used). Before use, put rosin semen on multiple strands of copper core wire. After the electric soldering iron is hot, put multiple strands of copper core wire on the integrated block to heat, so that the solder on the pin will be absorbed by the copper wire, and the part that absorbs the solder can be cut off. Repeat several times and all the solder on the pin can be sucked away. If possible, the woven bag in the shield line can also be used. As long as the solder is sucked up and gently pry with pointed tweezers or a small "one" screwdriver, the integrated block can be removed.

The circuit board has always been with us


Ahem, it's hot. On the monthly summary of the circuit board factory in Shenzhen, a newly graduated college student described the circuit board excellently and deeply taught many people who were not clear, did not know and had not heard of it. Also let the key word circuit board soared to the peak of the peak.


Circuit boards - let me have never touched my curiosity, after graduating from college. In the talent market of Shenzhen, I saw that kyPCB was recruiting, so I applied for Shenzhen Keyou Circuit Board Factory. In the written examination, the exam officer asked me a question, which made me step into the youth of struggle as an undergraduate student who had never stepped into the society. The examiners' question was: What is the most critical weather problem in modern society? My answer: green, environmental protection!! Let me successfully step into the work life after the university!!


Came to the factory, lived in the dormitory. The dormitory supporting the factory is relatively spacious, without the strictness of the school. The WIFI in the dormitory is also open, which allows me to have more time to study deeply in the part of work. When I reported to the factory, the buildings and machinery also let me open my eyes. Bang bang drilling rig, with no points of more than 1000 drilling speed, let me this just stepped into the society to see the importance of automation equipment, manual is completely unable to do. I just came into contact with the circuit board, and I was assigned to the punching workshop. After two days' practice, my colleague told me that the machine was foreign, and how much did it cost? Suddenly I feel like I'm dealing with a Rousselaus drill every day! Severe is not bad on everyone can think!!


From campus life to social struggle, is not used to. But in the circuit board drilling room, let me understand the importance of the circuit board. Originally in I have never touched, never understand the circuit board, the circuit board is in my side has been with me. Laptops, air conditioners, and cellphone core use circuit boards!! I was also a little surprised that I was so unfamiliar with him when they knew me.


When I entered the circuit board factory, the solidarity and mutual care of workers and friends helped me to improve my practical ability. Thanks to Keyou circuit board company, I was tested to enter the society and had a deep understanding of the wide use of PCB in the manufacturing industry. Let's learn more PCB knowledge together.


Keyou Circuit is a dedicated to PCB rapid proofing and mass production, with high precision single side/double side/multilayer circuit board (1-26 layers), thermoelectric separation copper substrate, multilayer industrial circuit board, power PCB board, medical circuit board, security PCB board, communication PCB board, automotive circuit board, instrument circuit board, military circuit board, composite bus copper substrate, can be Folding metal substrate,FPC soft and hard combined board, quality assurance, delivery on time, to sales as one of the high-tech enterprises.
