What? Do they use budget tights at NASA? I'm not surprised. MIL 338 HDB, also a good source, despite its rev status. Thx, Trikeman, eyes like an eagle, hey? /Inge -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Creswick, Steven Sent: den 17 oktober 2007 12:06 To: [log in to unmask] Subject: Re: [TN] JPL Publication 96-25 Inge, Maybe there have been no further updates beyond the original. Budgets are tight all over ... http://parts.jpl.nasa.gov/mmic/mmic_complete.pdf Would Mil Hdbk 338 be of any assistance? Probably not, but .... http://www.progettoatena.it/univ/gestione/handbook/338b.pdf Steve -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Hernefjord Ingemar Sent: Wednesday, October 17, 2007 3:09 AM To: [log in to unmask] Subject: [TN] JPL Publication 96-25 Anyone happen to have a newer version of 'GaAs MMIC Reliability Assurance Guideline for Space Applications'? My old version is 221 pages and released December 15, 1996. Little too old. I had some friends at NASA, but that was years ago. I need some help for analysis of intrinsic failures on PHEMTs. By the way, anyone who knows a method for removing ground rails over FET channels? Wet etching won't work, because it takes gate fingers too. Ion etching would work but is too expensive and too slow. Plasma etching will take everything, not only rails. Any genious out there? Not exactly a PWB matter, but from experience, I know there are many odd characters among TNetters.
