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...

CNC Milling CU clad board for PCB prototype fabrication - RF Cafe
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 am looking into purchasing
a Sharp 9x42 3-axis CNC mill.
I have since been given further justification by hearing of other employees
desire to quickly fab RF-circuits on copper clad FR-4. Their are CNC
machines available specifically for this purpose, but I would like to
be able to accomplish the same job with a standard CNC mill. The only
advantage I know of to using a dedicated machine is that some of the
models out there have the option to add plated through holes on the
Does anyone have any experiance in this area?[/url]

I appreciate the thought that
I would be able help out on this, but the CNC milling machines that
we use are all LPKF made machines and are designed to actually mill
I have no idea if a standard CNC machine would
make a decent PCB board. Then again, I don't know any real reason why
it couldn't. I guess it all depends on the operator and the ability
to convert the routing data to a machine language that the CNC mill
interface box understands.
As for plating holes on the fly, I
only wish it was that easy.
