RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

My Hobby Website:
These companies make the machines that are used to produce the products designed by engineers. As a newly ordained member of the half-century club who has been in the defense contracting and commercial design and production field for nearly 30 years, I can remember the days when most electronics companies had in-house machining capabilities.
I used to love going down to the machine shop to watch the lathes, end mills, and other precision tools turn out parts for torpedo nose cones, airborne radar system chassis and antenna steering units, and many other assemblies. I witnessed the slow, steady metamorphosis where the shops were turned into empty chambers. Only a few benchtop prototyping and repair tolls remained. It was a sad thing to watch. I even remember when companies like General Electric had their own in-house PC board fabrication equipment.
Now, most of that work is farmed out to contract houses. They do an excellent job, but the engineers and technicians do not have the opportunity to see their creation converted from paper (a computer screen nowadays) to a physical part. Sure it is probably best to concentrate specialties for efficiencies, but just as having a car that you can actually do your own work on deepens your knowledge of the vehicle, being able to see the product development process run from concept through to production adds a dimension to your professional experience that cannot be gained otherwise.
