RE: ESD Generator confidence test (humor)

Did you all know that an ESD charge may be well simulated by the famous 3M Post-it notes. My wife works in a company where life-size 3M Post-it notes are used with the paper side down to get rid of dust onder shoes of people entering a clean room. When changing sheets she get's loaded to a level

RE: ESD Generator confidence test (humor)

My first memorable experience with ESD was at the age of 10. I would build quite a charge on my body when playing basketball in the gym. And I would always get a hugh zap when I pushed on the metal handle of the water fountain. I knew just enough physics to know that a rubber basketball was an i

RE: Pencil erasers for pre-EMI cleaning? (cleaning mating surface s, chassis, )

Robert, The North American paper sizes are not irrational, just dated. The engineering sizes (A through D) were originally mainly used with the contact diazo (blueprint) duplicating method. The copies are all at 1:1 ratio with the original drawing, which was hand drawn in the days before CAD. Enla

Gaeten, I was searching for something completely different and came across this article. Hope this is what you are looking for. http://www.ce-mag.com/archive/2000/novdec/roleson.html Incidentally, the only difference I remember from '87 to '94, is the change for radiated emissions measurement

RE: Laser Safety

While it is technically possible to have a Class IIIb-capable component laser in a Class I 'system' the path there is not clear cut. Besides the emitter's technical issues (AEL, exposure time, radiant power, wavelength, to name only a few) you have to take in consideration the failure modes of t

Laser Safety

I am trying to gain a better understanding of lasers and I have had some discussion and been told some things that don’t make much sense to me so I am asking the group for some guidance. Here is my question. If the unexpanded raw beam of a Class III b laser was incorporated into a larger system,

RE: Pencil erasers for pre-EMI cleaning? (cleaning mating surface s, chassis, )

More importantly, North American paper sizes are just plain irrational. At least the metric sizes all have the same aspect ratio, so enlarging/reducing from one size to another doesn't result in a large band of unused space. Even the US Patent Office has given up on US "A" (8-12 x 11") or US "lega
