Reflowing a motherboard is the heating up a computer chip on the motherboard, or the complete board itself, to a temperature that causes the solder to become softer and reconnect cracked solder points. Of course it can be difficult to know exactly how hot a motherboard or computer chip needs to become in order to melt solder while leaving the components unharmed. The GPU is the most prone to are unsuccessful on most high end devices such as notebooks or gaming consoles. The most common difficulties with broken GPUs are no video, distorted video, or failure to turn on and post. Reflowing a GPU appropriately will fix any of the recently mentioned difficulties with a laptop or gaming system.cmos batterij
First thing you need to do is be sure to have the correct materials. You’ll desire a heat marker that is capable of putting out at least 550 degrees Fahrenheit. You can buy these high temperature guns at most local hardware stores and they are usually about 45 dollars. Next you’ll need solder, thicker rosin key solder works the best, and a penny.
Right now that we have our materials, you will need to locate the GRAPHICS that needs to be reflowed. Yourself the nick that needs to be reflowed take note of any large capacitors close to it and ensure you may hit these directly with the heat gun while your reflowing the processor chip, excess heat can cause some capacitors to burst. If you locate the capacitors are near the GPU and your concerned with hitting them with the heat weapon accidentally you can use aluminum foil to cover the capacitors. Place the penny on top of the chip with a tiny part of solder on top of the penny. Once the solder melts you will be aware that the chip is heated to a good temperature. Now set your heat gun to 550 degrees Fahrenheit and commence to heat the chip by holding the heat weapon three or four inches above the chip and rotate the heat gun in round movements. When the processor chip gets hot enough you are going to notice the solder on the penny becomes chemical. Possibly the solder convert to liquid the computer chip should be hot enough and you could take away the heat marker and allow the processor chip to cool down. In the event that the chip is cool enough go ahead and start putting your electronic digital back together. Test and find out if everything is working normally, if you reflowed the board effectively any issues you had that were being caused by your GPU should be fixed.
