I guess there's just been less documentation of Bitmain having some sort of repair training program, I haven't even heard of something like that until now. Is there any information about Bitmain's program out there somewhere? I've never been great with the technical details of miner repair and I happen to be traveling to China this summer (specifically Nanchang and Beijing), I'd be glad to take a detour to Bitmain or Avalon's facility to see how things work.
Bitmain is less forthcoming about it, and at the time did not want it known publicly as they had already decided among their customer base who would benefit most from the training. When I send RMAs to bitmain, its usually at least 250-300 units and I am one of their top large scale customers so im pretty sure thats why I was targeted. They even took us out on a yacht!
I know this isnt a really good description of what im trying to say, but from the pictures posted Avalon looks alot more "first world" in their manufacturing and build process than what I saw at bitmain. Much cleaner, nicer facility, much more attention to detail.
