Hi netters, In response to Ingemar Hernefjord regarding where are the big EMS players, and why don't you see them contributing to TechNet. Well i can only speak for myself. I do try to contribute and ask questions as often as possible, but as a research and development engineer the majority of my working life is spent in the lab researching and developing and therefore I'm not reading as much TechNet as I would like. But I do think this forum is an excellent tool for finding opinions and solutions to research and engineering issues and long may that continue.
