If not, what do you use for your prototypes?

Haven't we been thru this garbage before recently?


Yeah. But, is anyone interested in the way I do it? It's slightly
different from the rest of the posts.

I don't know. Are you good at it? All wisdom welcome!

I bought several sizes of diamond core drill bits that sand away copper
so that it leaves an isolated circular island of copper. On my (properly
adjusted) drill press, I can make lots of little islands of various
sizes on blank FR4 and use them for connection points. I use JL's
method of the Dremmel to make a VCC strip at a convenient edge and
solder bypass caps across the gap.

I've not found any problems with this method, but I'm not the SHF guru
you guys are.


I use carbide dental burrs in a Dremel, freehand, to cut away copper.

You can also put down Kapton tape and then copper tape patterns. Kinda
low impedance.

I occasionally use the old metal shear to make a collection of narrow
FR strips, as power busses and junction islands. They can be
crazy-glued onto the copperclad ground plane.
