It's proven again that baking a broken MacBook Air in an oven will completely destroy it

Perhaps thanks to God's blessing, some people have managed to revive their broken MacBooks by putting them in an oven . Blogger Alistair Wooldrich, who saw that post and decided to bake his broken MacBook Air in an oven, completely killed it, proving with his own experience that 'miracles don't happen to everyone.'
Baked MacBook Air: A cautionary recipe - Woolie.co.uk

It all started when Wooldrich dropped his MacBook Air from a height of about 30 cm one day. Wooldrich's MacBook Air had worked fine when it had been dropped several times before, but that day, perhaps because the impact was bad, the computer would not turn on even when the power switch was turned on.
The image below shows Wooldrich's MacBook Air when it was working fine.
The next day, Wooldrich followed the online support guidance and tried repair methods such as '
Having seen a repair method on the Internet that involves baking a MacBook in an oven , Wooldrich decided to bake the logic board of his MacBook Air in the oven. The principle of this 'oven repair' seems to be the same as reflow soldering, which involves preheating the board and components to about 150 to 170 degrees. Wooldrich used a pentalobe screwdriver and a Torx screwdriver to remove the logic board and digital I/O board from the MacBook Air and place them in the oven.
The oven used in Wooldrich's 'Oven Repair Method' looks like this.
According to a recipe on the Internet, the logic board is recommended to be baked at 170 degrees for 7 minutes, but there is no mention of whether it is necessary to preheat it or whether to apply egg yolk for a glossy finish. Wooldrich did not want the surface of the logic board to be as shiny as a commercial apple pie, so he decided to bake the logic board without preheating or egg yolk.
The logic board, heated to 170 degrees, 'didn't smell very nice,' but Wooldrich solved the problem with a simple and elegant technique: leaving the door to the outside open. After about six minutes of baking, some of the thin wires 'began to bend in unnatural directions,' but Wooldrich was pretty confident in his oven repair and decided to try to increase the oven temperature to 180 degrees for the last 60 seconds. When he did, the resistors and components on the logic board made a popcorn-like noise, blew out smoke, and the logic board itself bent in the middle.
Here's a picture of the logic board and digital I/O board after baking.
If you look at the arrow, you can see that the CPU has come off the logic board.
The USB port and MagSafe connector dangle.
Of the three arrows, the top arrow points to where the resistor that came off was originally located, and the resistors pointed to by the two lower arrows are wobbly.
After clearing the smoke from the oven, Wooldrich tried to solder the logic board back together and restore the MacBook Air, but it never came back to life. When asked if he should have taken it to an Apple Store for repairs, Wooldrich replied, 'I knew the warranty had expired and that it would have cost hundreds of dollars just to repair the logic board, so I gave up. I'm now considering taking it to the Apple Store to see how the staff there reacts to my oven repair method.'
