Micro Soldering

This is how a BGA chip is reballed for use in electronics.

Every tiny solder point has to match perfectly for the chip to work again.
The precision in this process is incredible to watch.

One small mistake can ruin the entire connection.
Watching the stencil line up and the solder form into perfect patterns makes this repair process surprisingly satisfying.

Tiny electronics like this power phones, computers, and many everyday devices, but very few people ever get to see how detailed the work really is behind the scenes.
