Don't attempt without practice and a proper station.

Pretty high, honestly. BGA rework on soldered RAM isn’t a simple swap — you’re dealing with hundreds of tiny solder balls under a chip, and a motherboard that absorbs heat unevenly. One wrong temperature curve and you’ve lifted a pad or cooked a nearby component.

Most damage happens from:

• Uneven heating – warps the board or cracks the BGA package.
• Too much heat – melts internal traces or pops capacitors.
• Lifting pads – if the chip pulls off before the solder is fully liquid.

If you’ve done BGA rework before and own a proper rework station (not a hot air gun from Amazon), the odds drop. If this is your first time, assume you’ll kill the board. Practicing on dead laptops first is the only smart way.

This is not a YouTube-inspiration project. Future you will appreciate the practice board.
