Thank you!

Hello, if you want some in depth info and video of how to do all the things asked in this forum , rework, solder, R&R chips

look at a guy in NY that repairs MAC boards as he has all sorts of FREE videos on how to R&R chips and how to protect other chips on the board next to what your doing.

No I don't know this guy but watch lots of his videos as he really explains how to do chip and board repair RIGHT

he has lots of youtube videos for all that sort of stuff, just search on youtube

>>> Louis Rossmann <<<
