[time-nuts] OCXO Support Board

[Mike Ingle]

Hi All,

I will second Bob's comment on choosing a program with PCB - Schematic
integration.  I can heartily recommend Kicad.  I own Altium designer, but
work remotely for an American firm from Germany.  The US office uses PADs.
We have finally agreed on projects going forward to both use Kicad.  While
Altium designer is more mature, and a little smoother to use, all of the
programs have quirks, and require that you become familiar with them.  So
far I am not seeing any limitations in Kicad that would prevent getting
good boards made.  And, many  prototype oriented houses accept Kicad PCB
files directly (for example EUROCIRCUITS) , which saves you from generating
Gerbers and drill files.

And Kicad just keeps getting better.
