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, Don W3FPR GW0ETF wrote: > > I have a question about removing dust particularly on circuit > boards.......I'm wary of inducing static by blasts of air or physical > brushing with bristles and I know you can buy expensive vacuum cleaners to > clean out the inside of IT equipment to avoid static damage; all the tools > and tubing contain carbon to prevent the build up high air friction induced > voltages which could fry sensitive ICs.
