Microsoldering is a must to survive in the repair industry in India because of how common it is to get your phones repaired. The second/third hand market is also huge.
As for where they learn it, there are tons of informal institutes, courses teaching people mobile/laptop repairing.
Although I will say, the people doing repairing in India have very little knowledge about basic electronics.
There are companies like Borneo (and other Chinese companies) selling schematics and laptop/phone specific repair/unlock guides doing much of the heavy lifting of distributing knowledge in this area.
As for what tools are involved etc. you can search "Learn Mobile Repairing" on YouTube and you'll get a lot of videos.
