Steve you sure did it again ! Considering I did same fire duty as Matt ; now I think if I should repent and pull all the damn plugs (hundreds of pc's around !!!). And the machines ; the surge would be interesting as well ; and the chaos would take a 1/2 hour each morning . Matt I totally agree with you but the reality of it Still; if I find any kapton on 3phase cores I'll throw off the main fork ! So far it's only question who sniffs the smoke first , security chaps or the funny things on toilets ceilings (would you believe this nicotine addicts ?) And ; be fair guys ; how many of us have a timer on wave pot ??? With a drastic surge early am when even the guard slumbers on chair ??? Some of the half tonne elephants would take till noon to heat up ! And we petty bout pc's ?

Hi Steve, the reason why I shut down all my equipment (some CAD workstations including a "server" under Windows NT, a small IR reflow oven) every evening (I disconnect all with a big red main switch) is the possible fire hazard. I feel better if I know the only three boxes which can burn my office are the fax machine, the answering machine and the telephone switching system. In a former life, had a PC power supply which exploded with spectacular smoke production. It was unpowered, but not disconnected, and thus the main input EMC filter was under power. And you know how this cheap stuff is built: no fire proof metal housing, and the whole PC power supply PWB was burnt..... Imagine what happens if nobody with a cup of water is near (after unplugging!! ;-) ) One of my board manufacturers lost his whole plating equipment because it was powered overnight and a little mouse had the opportunity to produce a little short circuit, too small for firing the fuses but big enough to burn the house. Just my two cents Matthias P.S.: I was seven years in a voluntary fire brigade. About the half of all fires were technical defects in powered, unattended electric or electronic devices...... ----------------------------------------------- Matthias Mansfeld Elektronik * Printed Circuit Board Design and Assembly Am Langhoelzl 11, D-85540 Haar, GERMANY Phone: +49-89-4620 0937, Fax: +49-89-4620 0938 E-Mail: [log in to unmask] Internet: http://www.mansfeld-elektronik.de ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
