[Elecraft] K3: Brush or Blow Dust?

[Don Wilhelm]

Stewart,

In the past, I have understood that when ICs are mounted on the boards, 
the static susceptibility is greatly reduced, so air-cleaning of 
assembled boards is generally OK.  That may not be true of any single 
board since it may have unconnected inputs at the pins, but should be 
true for complete assemblies of boards.

I have taken the air hose to many old computers and have had no 
identified problems.
I have never had to do the same to any ham gear that I have encountered 
because there is just not that much dust accumulation.

73,
