Small circular pc board

Hello -

I need to lay out a small circular PCB (.72-.75" diameter). How do I get a circle this size?

Also, the board will need two slots in it for mounting components through the board (mechanical - not electrical). Any advice?

Could I supply you FR4 board to use for my jobs?

I want to place a microstrip antenna on a PCB. However, the resonate frequency of the antenna will be changed by the properties of the PCB substrate. Rather than use a PCB which has a well defined value of Er like Rogers, if possible I'd like to use cheap FR4, but measure the permitivity myself. Once I know the properties of the board, which I can measure with a network analyzer, I'll be in a ...

Can other PCB manufactuers use PCB123 files?

I'm trying to ascertain if PCB123 can be used to generate file which any decent PCB manufacturer can use, or whether one basically has to get the boards made by Sunstore. Can PCB123 output standard Gerber, NC drill files, and anything else that another PCB manufacturer would use?

I want to avoid "vendor lockin" where one is forced to use one company.

As another point, can you take files that are produced by KiCad?

PCBs for LED lighting applications

There's a global trend emerging, even before the previous trend had reached completion. After nearly a century of standardization on incandescent bulbs, LED lighting for bulb-type applications are coming on even before Compact Fluorescent (CFL) bulbs could achieve a majority foothold in the global marketplace.

Eliminating Japanese Nuclear Reactor Led Lights

Some would say that's just as well, but this discussion thread is not to compare the strengths and weaknesses of CFL and LED.

Instead, ...
