For those who confuse about removing your CPU ic, Here is a new way to do it easily....

Let me introduce"GLUE REMOVER". This GLUE REMOVER is a water epoxy that can be remove glue at cpu or ccont and any ic stick with glue.

The method is easy. You just need a blower station,cutter and GLUE REMOVER.

You just put a few GLUE REMOVER surrounding the ic that you want to remove. Then ,wait about five minute and use your blower to blow it about one minute, after that use your cutter to pull it up slowly.Finally, glue will automatically stick at ic. I can guarantee the glue will stick at ic and it wouldn't stick at the board. So that you are non need clean the glue at the board.

This method is faster and easier. It only sell US$15.00 per bottle weight 50ml.

Courier Charges are depends on destination.
