Updating ps3 from usb
When the board cools, the balls are reformed with the help of flux, which gives them back their elasticity.
Don't worry, the oven will not get hot enough to "liquefy" the solder and cause it to pool into one giant glob, but only enough to cause it to "goo up" and reform each individual ball.
The guy does a great job of showing not only how to disassemble, but reassemble, the PS3. This paste transfers the heat from the chips to the heat sink, and if your Play Station's paste looked like mine did, it's obvious it wasn't doing its job. To get the edges of the chip, soak a Q-tip with Goo Gone and wipe them off.
To clean it, drip a little bit of Goo Gone onto the chip you're cleaning and let it sit for about 30 seconds. When it's clean, wipe it down with rubbing alcohol.
But I will say that if you follow this guide, your chances are good. There are several prevailing theories, including a faulty power supply, corrupted hard drive, or virus circulating through the PSN (which is probably 100% false).It comes in a small bottle with a pipet) - Goo Gone Extreme, Goof Off, or similar - Q-tips and Paper Towels (or Napkins) - Aluminum Foil - Arctic Silver 5 Thermal Compound (can be found at Radio Shack) OR if you're on a budget, you can get the cheaper ceramic based compound.It should still be an improvement over the stock paste, but AS5 will be better if you can spring for it.Now, the last thing is to "critique" other methods of fixing the YLOD.The main one that you may have heard of is the heat-gun method, which works, but has several downfalls, the first of which in my mind is the price.
