I did so reluctantly and on old hardware at > first, (I was worried about static too) - but I've never had an issue. I've used high pressure air too and without an obvious problem so far. However, static generation can occur this way, and it can be fatal as well as just damaging to electronic chips. In FL, I could not get static generators to run at all in a lab with natural humid air, but up here I can kill an IC just from walking across the room and touching something. I'd like to get some real data about this form of static generation and its suppression and then decide whether to ignore it. Static damage is often a subtle internal "fracture" in a chip that eventually makes something flakey and/or dead. The less common catastrophic forms of damage are easier to discover by test. Chuck
