How does a person learn to repair MacBook logic boards?
Hi! I'm wondering how people go about learning to repair logic boards. Not replacing components (DC-in, memory, etc.), but actually repairing the board itself when it has liquid damage or other issues that are typically fatal. I've sold a lot of dead MacBooks and have noticed there is definitely a market, and I've also successfully used flat-rate services which pretty much repair any MacBook board for a few hundred dollars. In my experience, they haven't switched them out -- they've actually fixed the board. And not only that, but the high success rate leads me to believe that the repair process must be fairly systematic and straightforward.
I'm very interested to learn, so I'm wondering, is anyone aware of resources for doing this kind of thing? I'm assuming it involves soldering, chip replacement, and some pretty hardcore electronics knowledge. I've asked people who do this for a living, but for obvious reasons they don't seem too interested in divulging the info.
