Hi,
I'm building a PCB, roughly based on a Leach. However, I'd like to have the input and VAS sections on one PCB, and the predriver, driver, and OPS on another board.
The idea is to use mating pcb mounted headers to connect the boards and provide mechanical mounting. Any suggestions on pcb mounted header/connectors to use?

Any of the 100-mil grid type connectors would probably work. If you're working with higher voltages or are worried about capacitance between adjacent pins, you can always skip every other row.
Another solution would be to align the holes in the VAS PCB with those in the output PCB and just run a standard Molex connector with some wire between the two. That way you can adjust the height between the boards by choosing different standoffs. It might give you more flexibility.
I'd run the high-current supply runs directly to the output/driver board and have a separate run for the VAS PCB. This would limit the connections between the VAS and output boards to just a couple.

My advise is that you have one single pcb.
I hear you. But then I was planning on trying different input, VAS, and feedback circuits, which could simply be plugged in. A key feature would be keeping the connections short.
You can get the gold plated Molex 0.100" headers from Digikey. They can also make up ribbon connectors with any combo of male, female and solder tail connectors. It isn't difficult to make the female connectors -- and I use CAT5 cable or microphone cable.
Good for prototyping -- but the best connector is no connector.

I'll give the Molex a look, but want to avoid something that requires a cable.
Thanks for posting the pictures.
I was looking at a Harting #09062152821. Looks nice, but each end is $9 or more. The pin header sounds more appropriate.
