RF PCB House?
« on: July 22, 2014, 04:35:31 pm »
I'm looking to do a couple 4 layer PCBs that have RF components in the 5-7GHz range.  Does anyone have a favorite house for doing these sorts of things?

whaddaymean ? to do the layout work or to make the bare board ? any serious board house can make this. Pick one of the Nelco or Rogers RF substrates , pick the layer stackup , plug the numbers and off you go.

To make the bare board.  I have my favorite houses for high current, and another set for "cheap crap quick", but I don't yet have a favorite house for RF.

All of my RF work has been either 900M or 2.4G, and honestly wasn't all that complicated - mostly I did antenna design or front ends with just a handful of RF components.  This will have a few copper defined components (filters and splitters) and is more sensitive to interference than other designs I've done.

What is your favorite "serious board house" for this?

Thanks!

I know PCBcart (chinese shop, ok place) offers RF-substrates at least: http://www.pcbcart.com/ No experience with their RF-boards though. I have a bunch of friends who have ordered regular boards from there without a hitch though. I think you need to email the design files to them to get a quote for RF-boards, can't use their automatic quote.

Where are you located? Eurocircuits offers Rogers material IIRC.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Also Brandner (https://www.brandner.ee/) has Rogers RO4003C in their stock list but I have never ordered an RF PCB from them. Plenty of other boards though with very good service.

If you are in Australia, http://www.lintek.com.au/ are good. Their design rules document http://www.lintek.com.au/resources/datasheets/Capabilities%20and%20Design%20Guide%20V2.4.pdf is very clearly written.

Chris,

Iconic PCB make bare boards in Brisbane using mechanical milling process. Mechanical process will provide a cleaner edge profile than chemical etching.

They have made some cavity boards in Rogers material in the past.

Interesting. From your experience, besides 3D-iness and miniaturization does "cavity board" give any other advantage over simple planar board? Which CAD tool do you use?

The process relies on mechanical etching. Gerbers are processed by Graphicode Gerber editor which also generates G code.

Cavity structure was a part of resonator design.
