I'm contemplating a project that would really benefit from a cyclindrical, not a flat, circuit board.
The board would actually just bend 90 degrees, it would not be a full circle.
The arc would be about the size to wrap around a coffee mug, with the heigth of the board being about 3 inches. The length of each of the legs would be about 3 inches and 6 to 8 inches, extending straight out at 90 degrees from each other, after the curved region. It would be SMT and partial TH components.
As a personal project, I'd be looking for 4 - 8 boards, funded by me, not off a project account.
I've used ExpressPCB in the past, and I don't know Eagle, or other board layout software, but I could learn whatever it takes to get the project done.
So, any thoughts on curved surface circuit boards?
This link to a YouTube Video of a Mini LED Light Bar, (not my video), shows the underlying concept. The boards on this mini-light bar are curved, with LEDs installed around the curved surface.
