To all... I need some help, (those that know me can keep your wisea## remarks to yourself). On Tues there was some discussion relating to 55110F and 6012 with Susan Mansilla from Robisan Labs advising their customers to use 6012 UNTIL 55110F is REVISED!! Sooooo, I get my latest copy of MIL-PRF-55110F and noticed the advisory on page 1. "Inactive for new design after 31 December 1997. For new design use MIL-PRF-31032" DUH!!! Where did that come from, are they still revising 55110F because nobody told them about 31032 and what about 6012???? Does anyone know how they all play together and what is really happening in the design/fab world ( in simplistic terms of 25 words or less - phone call would also be appreciated if that's the best way to explain the relationship) Big thanks in advance..
