Here's a closeup of my Antminer.
1 - As I've understood the R66 transistor is where I should add pencil graphite (and there are 16 of these albeit with different numbers).
2 - It has kind of two blank edges and the middle is matte dark gray. Does it matter where I apply the graphite?
3 - What happens if I apply too much? Will only the HW error increase, or can the hardware get permanent damage?
4 - What happens if I don't apply enough?
5 - It should be applied when the miner is off, right? Should I do all 16 at the same time?
6 - Is it necessary to use a voltmeter? Can the measure be made when the antminer is off? If I don't use the meter, is there another way to determine if the adequate amount of graphite has been applied?

1 - Yes
2 - Not really - so long as you join the two ends.
3 - You erase and try again.
4 - You put more on.
5 - Yes
6 - Absolutely. It is impossible to apply this mod without a voltmeter. You can measure the ohms when the miner is off to determine if you put on enough or too much.
