Stacked Right Angle Headers?

[CutRock]

I would like to be able to put two >15 pin right-angle headers on the back of a board that I'm currently designing (something like this). It would be fine, and maybe even preferred, if one was mounted upside down, but I haven't found an easy way to accomplish this without having both headers using the same vias.

The alternative is to put both headers side by side, though this would increase the size of the board beyond my target size and make the connectors less functional.

If anyone with a little more experience and knowledge of available components has any suggestions, I would be very grateful to hear your solutions.

Thanks!

Do you have to use right angle headers? Why not put two straight headers side by side on the top of the board? If you use the crimp connectors with ribbon cable, the ribbon will come out at a right angle...

Thanks for the suggestion, Doug. Unfortunately, they must be right angle headers. The end goal is for these to be exposed out the back of a synthesizer module so that parameters can be chained from one unit to another. To this end, it would be ideal if they could be stacked atop one another so that i can use short ribbon cables to tie modules together.

My current solution is to purchase solder pin'ed headers and try to bend the pins to make nice long (and hopefully less error-prone) surface mount pads. This way, I can mount one header from the top of the board and one from the bottom.

I know this solution is very makeshift, so if anyone has any other ideas, I'd love to hear them.

Thanks!

One of these on the top layer, one on the bottom. That is if you are not opposed to surface mount.

Mike, that is beautiful . Exactly what I was looking for. They're about 3x the price, not kept in stock and the minimum order is 3860, so I think I'll try to bend my own leads into a similar shape. Nevertheless, it's good to see that my initial solution wasn't completely out of left field.

EDIT: I looked through some similar offerings at mouser.com, and they all are considerably more expensive and often not stocked. For now, I think I'll stick with my original plan.
