nice to meet you. It is Doraiba tv. I will upload a simple repair image today. What you see on the screen The cpu socket that goes into the notebook. Between one and two weeks I have received two repairs for these laptops. If you look closely, The leg of the cpu socket is broken. I talked to the consumer. I have joined the cpu socket part. I look more closely Here, The other part and two places We made about 5 to 6 joints. There are marks on the cpu socket where the pins are joined. I wiggle. I move a little. It is pulled out like this. Fact that it is junction It’s a task to reattach anything that has fallen. The spacing of the cpu socket pins is quite narrow. And Soldering can be done by soldering iron. It depends on who you look at The bonding itself It is not that hard work. It’s a nuisance. Honestly, it’s a bit of a nuisance. It looks like five or six. There are a couple of places elsewhere. I have about 5 or 6 joints. I can not boot once I have symptoms that can not be confirmed. The cpu socket part that you bonded It has fallen. One has already been broken and taken away. Another thing you can do is touch it. Of course, in the case of desktops Because the price of motherboard is low Like this It is better to bond rather than replace It would be cheaper in the cost part. But If you get it wrong, In this way, When you fall I may be in trouble later. Of course, you can put it again. I can do it again. It’s a pretty annoying situation. Until we find that this is causing the process … You will have a hard time. In the case of this consumer, If you talk about this in advance, it’s easy to find Now, in this case, it is completely broken and I am cut off. That’s the other part. Of course, bonding is not wrong. When you see it for a long time, it is true. And there are a few reasons to not replace the socket itself. I do not see the repair cost actually. There is a part where the unit price does not come out while repairing. And what I’m going to show you now Socket of the same model. Foxconn products. The new products come in this way with the cover and the packaging. If you do a comparison, it is definitely a clean new product. In this way, it will be a comparison. In the case of this socket, it varies from manufacturer to manufacturer. I use sockets from multiple companies. The same standard does not mean everything is perfect. If you see here, Foxconn. There are companies like Lotus and there are several companies. There are products without the maker notation at all Depending on the model, The size of the plastic and these parts are different. There are realistic parts that are difficult to repair. This time, I’ll show you the first time. I can not see the back of a cpu socket. Very small as you see There are balloons. Common video chips, cpu or main chip It is made in bga type. In reality, there are not many places selling such sockets. There is no margin and there is no demand. It is all import. I do not do this well originally. I was forced to import a small amount. It takes more than a week to get paid. You’d be a little boring to wait. The work itself is bga way anyway Work is more difficult than you think. In the process of removing an existing socket If you make a few mistakes, Parts connected to cpu The leads will be cut off. If so It becomes a state that it is impossible to actually play. Because of these risks In fact, I do not want to replace the socket. As a rule, That’s right. Rather than a junction It is correct to use it to replace the socket. There are realistic difficulties. price Domestic supply and demand, operational risks, repair unit parts There are many things that do not match well. Once a day Remove the cpu socket To the process of reattaching I’ll try shooting. I need to get ready. I’ll get ready and shoot again. I removed the socket cover part in advance. Because there are devices around Taping work in advance. It is a good idea to take a picture of the board before you remove the socket. Because there are also elements inside the socket In any case, During other work processes There is a possibility of deviation. There are many devices on the back. There are some devices on the side. Even if heated directly above In the case of a cpu socket, it is a bit different from a typical bga chip Because the plastic cover is blocking and there is a bolt under it The temperature will be higher than normal chipsets. The other devices on the other side also need to be careful. When you’re ready Let’s work on it. First, You have to apply it with a syringe. I applied a little more than usual. Because these fluxes have to go under the socket Through the plastic part of the socket down to the bottom I have to go in. It should be applied sufficiently. If the amount is insufficient, it is more likely to become a problem when removing I will push it inward moderately. Inside the socket It seems to have entered enough. Actually uploaded to bga I will work on it. Because of the amount of flux, In the case of central elements, It is severe. Be careful when working. Then we move to bga equipment and shoot. There is a difference between hot air and ir. As you can see, the cpu socket has been removed. This is the original cpu socket. It is well removed. The mark that the pin broke is still there. It seems that the motherboard did well without damage. I want to remove the remaining part. As you can see, the pcb pattern is well organized. One more clean wash Before I put it on, it was a bit messy … I will finish it. The cleaning work is finished. This is a new cpu socket. It was already there. I’m missing all the bills. The new product is in it. I’m going to work now. I hope it works. One of the hardest things about working with sockets Temperature related. Temperature is the most important part. If it is the same now, the back side is also good without big damage. There’s one more question. There is left to stick. Just like when you put it off Heat transfer With a typical bga chip It is higher than bga type chips. These chips heat up from above and give a temperature in the bottom plate Lead melting temperature It’s approximate. For these plastic products Models like cpu sockets It is tricky to catch the melting temperature. Just when you unplug the socket Do not know the exact temperature of the board. Because of that part, there was a little difficulty. There are also such difficulties when pasting. Actually put on bga equipment After you’re done I will shoot again. The socket is done. It is finished well. It’s clean. Good. To test I installed the cpu socket inspection device. What we see here is a data line. If you put 3v or so, it will come on. The data line connection is good. Finally Actual cpu Mounting This time again with memory test equipment Do the test. I can not see it because of the light. It is coming in very well. The broken part of the socket I did everything. The rest of them have to go through the repair. Today is simple It is the model that the cpu socket pin is connected. The joint portion repeatedly drops again, The cpu contact is not working properly It was a video to replace the cpu socket. I can do this if the unit price is right. It’s a little dilemma. It was more than Doraiba TV.
