Werner (and any one else), A colleague showed me a copy of the May 27 issue of USA Today Editorials. Your letter to the editor "Communication satellites vulnerable to solder failure" was very interesting. Do you (or any other TechNet subscribers) have any more details on the prevalence of solder fatigue as a documented satellite failure mode? -- Karl Sweitzer voice: 716.47.77546 Eastman Kodak Company pager: 716.25.33681 800 Lee Road fax: 716.47.77293 Rochester, NY 14650-3118 mailto:[log in to unmask] ################################################################ TechNet E-Mail Forum 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://jefry.ipc.org/forum.htm) for additional information.
