Wow, this is awesome! It's one of those thoughts that everyone has- so much of making a PCB is totally menial and/or institutional, like part selection and supporting circuitry. Death by a thousand cuts, but many small problems (like placement or autorouting) are actually quite hard. Taken together it's an intimidating task.
This is the next big leap in design for software, electrical, and mechanical things: semantic descriptions directly to solutions.
Prototyping is an excellent application. Whats your support roadmap look like? Add more chips so you can continue making small widgets cheaply? Any plans to get into higher-risk design work? If you can reliably deliver high frequency/radio designs near FCC limits, that frees up a lot of RF engineers. For anyone who doesn't know, the cost to navigate FCC regulations is huge, and testing is worse (10k tests with months of wait, worst case). Probably even more people would be interested in high power designs, given the surging popularity of lithium personal transport and vehicles. Mains voltage/mixed signal designs would also be huge, but that's a whole other kettle of bears. I'm sure you've got internal metrics tracking what you all spend the most time doing and where you're bottlenecking. Even past the huge tasks of advanced engineering there are opportunities to integrate with 3d printing, automated enclosure or laser-cut design. I suspect/hope at some point in the future you guys will be hiring a LOT of people!
I'd love more examples, even on the front page. As long as they're relatively dense, readable and well-laid they'll inspire a lot of trust in engineers. Also, I think test fixturing is a strong asset and you guys should feature it more heavily! I'm not sure how you guys do it, but I'd love to see real examples. It might be the best suited automation of the things you guys do. Designing a comprehensive test fixture can take almost as long as designing the actual part, but with the basic functionality defined you could generate test routines, circuits, firmware, and jigs automatically. And my favorite kind of test jig looks like this[1], so gerbers are all I need to be happy.

I prefer clips to sliding holders like that, but I couldn't find a picture for reference. I like to put a few pads around the corners, then solder a small tab to use as a clip so the PCP only has to be held down on one side. Ideally I'd have a detent on the other side but I've never had a long enough test routine to warrant figuring it out.
- DHaldane 8y agoThanks for the feedback on the web page - we just mapped your comment to a todo list. For our roadmap, we'll be adding more and more chips, and improving the design software so we can generate production-grade designs as quickly as we design prototypes today. There's a lot of physics to bring into the design loop, but it's all very feasible. Love the enclosure co-generation idea. We have done a lot of computational design/fabrication for 3D structures in the past. I'm with you on the test fixtures! That image doesn't load for me though. I would love to see it.

- ur-whale 8y agoLOL, reminds me of these old 50's circuits where components were mounted vertically and sandwiched between two PCBs http://www.cryptomuseum.com/crypto/usa/kw7/img/cordwood.jpg http://www.cryptomuseum.com/crypto/usa/kw7/img/cordwood.jpg
- DHaldane 8y agoYeah cordwood boards. Love it. Believe it or not, this fixture is actually advanced for the testing industry. Most test fixture houses prefer to individually wire-wrap each pogo pin instead of using a PCB for connectivity. You end up with this terrible thing: https://imgur.com/a/pLHF648 https://imgur.com/a/pLHF648
- DHaldane 8y agoThanks! Yeah, we've been designing fixtures like that and have built some specialized automation to do so. The fixture design can also be co-generated when we design a PCB in our system.
- petra 8y ago// This is the next big leap in design for software, electrical, and mechanical things: semantic descriptions directly to solutions These kinds of tools are starting to be available in architecture and construction engineering, and in chemical research. Maybe it'll sweep across engineering. I wonder how future engineers work will look like .
