[Elecraft] "Metal muffin baking tins are good" -- was " K3 ESD"

[David Gilbert]

I thought we were talking about putting parts INTO the tin.  If you 
gradually equalize the potential of the parts with respect to the muffin 
tin before putting them into it, yeah ... that will work OK.  But then 
the resistor to ground from the tin is a don't care .. it doesn't 
accomplish anything as far as ESD goes.

Using the same protocol as stuffing a PC board is good advice, but the 
only thing a resistor to ground accomplishes is to provide a reasonably 
common reference point if you're moving stuff (components, tools, 
yourself) around from place to place.  Once everything is in the same 
spot it doesn't have much meaning.
