Installation of headers should be a snap when the connector can be used as an assembly jig.
That's what I was thinking in scaling the graphic, only the horizontal spacing would be a given?
Then we should be looking into machine pin headers with their round pins I'd think?
Yes, I have some 0.52 round header pins on the way, but couldn’t find any 2mm pitch longer headers (probably will need ~12mm length) with round pins.
This was just to test the spacing of my HDI-45 layout in Eagle. Although I did confirm all the pins fit very snug and were making secure contact, so if someone doesn’t want to go through the expense and hassle of individual pins for all ~20 or so pins, the square pins in a traditional header would likely work great.
FYI, here's the DB15 version of the board:
The routing was a bit more complex (the VGA pins were so simply it allowed me to do it all in on layer, this one unless I missed a routing opportunity, required two layers and a couple of vias to get everything connected properly.
