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 World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

General question on Packaging and circuit Board - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

I have an open and general question regarding
material such as Roger3000, LTCC or Ceramic..
I have heard people
complaning about those material at frequency above 30GHz, either for
the loss, for the unstable lateral dimensions or price.
has experience with those type of material for either packaging or circuit
and could give me more details.. What problems do people usually face
with those type of materials?
Is there a frequency at which there
is no solution for chip on package or it is to expensive(above $100/inch^2)??
or just to much twinking required???
I hope my question is not
to vague... and there is some kind of response...
