Hi ya'll, Not to start another thread about something that will upset people, but lately in the media there has been some talk about Kapton (tm) materials being somewhat unstable at elevated temperatures...there's stories about this with the recent crash of Egypt Air flight 990... I, as undoubley as possibly many of you, have always understood that Kapton (tm) tapes are what you should use when high temperatures are encountered. I've used it on numerous assemblies to in the past to prevent such things as a metal connector body connecting to a via that was mistakenly laid-out without mask beneath the footprint. As a big as a pain in the butt as it was, we would cut a teeny piece of kapton (tm) tape to cover a via so that there was no chance of a via to short to the connector. This is just one example...there have been many other instances in the past (crystals, oscillators, etc..) or with other components where I've used Kapton (tm) tape to do similar things...the tape needed to stay with the assembly as a finshed product. Should I, or designers who specify the use of Kapton (tm) in this manner be concerned about this? Or is this just media hysteria? -Steve Gregory- ############################################################## 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.
