Removing Chips



This FAQ will hopefully teach you how to correctly remove electronic components by use of a HeatGun/oven.
A heatgun is recommended and safer to use.

Things Required:
Heatgun
Tweasers/ Small Flathead screwdriver
Something to put the component on to cool off ( Styrophome, Paper towel etc)




We will be using a board which contains a soldered Intel 386SX-16MHz. I want to remove the cpu, perfectly preserving it and the pins without causing any damage.



Keep your heatgun about 2-3 inches above the cpu, and make sure all soldered pins are getting equal heat at all times. Hold above for about 15-30 seconds, then take your tweaser/flathead screwdriver, place it under the corner- gently lifting it until fully removed.



Wasn't that easy? The little pieces you see on the pins were dust and little pieces of rubbish that got in the way during the operation; they were easily removed with the use of my finger.



Look at those beauties! All the pins are perfectly preserved for collection. Stay tuned for my next and hopefully to become a very helpful FAQ- that involves reinserting this same chip onto the same/different motherboard which would ultimately lead to the salvation of videocards/memory. I'll explain how later :)

ENTERPRISE

Kl Faq Well Done

I try, I try XD

thats cool man

If you're heating that chip enough to melt the solder you're probably also heating enough to damage its internals...

Thanks. I guess it was you that voted me down?.......
The answer to your question: You're not heating the chip itself to remove it from the board, you're heating the BACK of the board to soften the pins on the chip enough to remove it, and at the same time keep them all intact. So afterall, the chip is not being damaged..
I heated the one above just to show how it works, and normally if you dont expect it to work again, doing it on the top is a lot easier and saves more time.

Thanks again. :P

Incorrect: the chip is soldered there by a verry similar process. ;)

Good point SPHERE.

This is interesting...

So could you remove the RAM chips from 1 vcard can put them on another?

Theoretically, this process should work as long as the chip you replace it with is the same speed/make/package. :)
