My modded switch lite with new shell and joycons! Got these from aliexpress since the original shell was cracked and the joycons had some dead zones. Whole process took about 3.5 hours (with child interruptions). I had some pics of the soldering but seem to have lost them.
I have chipped a normal and lite switch, the soldering itself is not the worst but seeing what you’re doing is hard.
Plus on the switch lite, take great care about the battery connector. It’s super fragile and can pull out when disconnecting it
