HI, I have a 820-3330 with missing resistor all over the board ( maybe previous techinician mess this up )
so i place all missing resistor I can see, plug in magsafe., and the fan turn on for 1 second and then stop
ppbus 12.6v
pp3v42 3.3v
all_sys 0v
pp3v3_s5 3.3v
I try to reflow smc, and then i got dim green light with fan running at max instead
tried to reball instead, but the smc pad at pin 156 NC_SMC_T25_EN_L is missing, and I don't see this pad go anywhere on boardview, any idea ? or should i ignore this line ?

"NC" stands from Not Connected; so don't bother with that line.

Which voltages and signals do you get now?
