How Baking A Motherboard in the Oven Worked for Me

by:Rocket PCB     2019-08-27
In the past, I have read some articles claiming that depending on the problem, the computer motherboard can be fixed by baking in the oven.At first, the idea seemed ridiculous to me.I surmised.With this, I ignored the idea of putting a printed circuit board in the oven and continuing my life.
.....Until a wonderful Saturday, my parents called me and complained about their laptop.Obviously, it can\'t be operated at all.The fan will start and the led above the keyboard will flash, but the screen is still blank.After about 20 seconds, the computer will be turned off and restarted, and the process will be repeated.
In the electronics field, I understand the problems caused by components and their failures, however, my electronic experience does not include a broad understanding of the internal work of the laptop.My parents (bless their hearts) think that I am a computer master and often ask me for advice.How do I solve this problem?After looking at the device, I can see that no component is obviously damaged.
This does not mean that some bold capacitors do not fail, but at least there are burnt marks or broken pieces inside.It seems to me that some of the solder joints have broken and some of the key parts are in intermittent contact.The Ohm and voltage readings of one billion objects on the board seem impractical.
What is a person going to do, and what is lunch time almost?Just then, I reconsidered the old idea of baking the printed circuit board (PCB) in the oven.After following the online tutorial to take apart the laptop (which may be harder than removing the car), I left a pile of plastic and my cat was quickly banging a small screw next to it, there is also a very clear PCB.I removed the processor, battery and two wires as per my own wishes and was approved by someone else\'s advice (note: Not marks!) Outside the board.
This leaves only the circuit board, relatively cheap parts, traces of copper and welding on the board.The online time and temperature vary, but the average seems to pointHeat the oven to 385 degrees F, once ready, place the motherboard on the biscuit paper inside the oven and isolate it with the screws in the corner for about 7 minutes.I have accumulated a pile of ruins that used to be laptops, so I don\'t think there is courage, no glory.
Anyway, I\'m pretty sure my father is buying a new laptop.I preheated the oven to 385, made a sandwich, repositioned most of the screws that knocked my cat under the sofa, and then used the hand-Twisted some wood screws in the four mounting holes in the corner of the motherboard.Like a Food Network star, I threw the board on the cookies, threw it in the oven, beat my hands together and tried to convince myself that I wasn\'t going to burn the house.
I can definitely smell board cooking in a few minutes.If you were a child who participated in the fire lighting operation, you would smell the melted plastic.The board has been in the oven for a full 7 minutes and I am not sure if there is enough time for solder to liquide and make the connection.
I was careful to keep the board in the oven all the time (although I did grab a fan and open all the windows ).After 7 minutes, I turned off the oven and let the board cool in it for about an hour.After the PCB cooled, I took it out of the oven, re-sealed the processor, plugged it into the battery and started reassembling the laptop.
Without being too advanced, I powered the device before the entire assembly was completed, assuming the laptop had to be taken apart and the trouble shooting had to start over.Holding my breath, I plug the power into the socket and press the power button.LEDs flashed.The fan rotates happily.Expect bigger and bigger.Finally, after a seemingly slightly slower start --Up, the display lights up the PC vendor logo s logo with glory.
Bake the motherboard!The laptop has been running for more than 18 months without any problems.In fact, baking the motherboard even solves the second problem that the wireless network card on the laptop does not work.The product is like a brand new one produced directly from the factory, the only problem is that it seems to run a little slower than before.
Oh, the sacrifice we accept for luxury.
Is this an isolated incident?Was I lucky just now?Because the internet is full of dynamic results for baking boards, there is no way to answer this question with confidence.After bakingIt all depends on the problem, the severity of the solder joint break (if this is the problem, first of all), and, like any problem in life, there are a lot of other factors.What I can prove is the oven-bake-your-The board method not only fixed my parents\' laptop, but also fixed my desktop computer after the screen started to turn bluegreenish hue.
The cable for my monitor and the monitor itself are fine.Looks like a nasty solder joint is broken, take the R in my RGB, leave the image of the Wahoo chief on my desktop and become an invisible black hole that looks black) Stayed in the oven for 7 minutes and then slammed \"technicolor \"!!!In general, the baked motherboard does not guarantee work, but it can do this.The article is intended to describe the reasons for the board\'s work and even tell others to try this trick.
There is definitely a safety issue when baking synthetic materials, and I would suggest having the little guy play in the backyard while trying to fix the Motherboard this way.Carry a fire extinguisher with you just in case and make sure the house is well ventilated.As a disclaimer, you try to bake the motherboard at your own expense and are responsible for any damage to the motherboard, oven or property (including yourself.
...Yes, my working partner asked me when to bake a glass Xbox or DVD upside down cake.Everyone is a comedian
