Pretty cool, but I think the PCB design will need a bit more work before it can be assembly house produced. There seems to be a lot of pointless via in pads that are not plated over (plated over costs $). From most assembly houses I've dealt with this is a big no-no (usually they'll still try, but expect tombstoning and other bad things as solder is sucked through the via). Same thing with the QFN/P parts.
If I had a copy of OrCad I'd love to check out the actual schematic/layout, the Upverter doesn't seem to be updated.
- GeorgeHahn 13y agoI agree. The via in pads was done more as an experiment to see what would happen - I'd never tried it before. They lower the inductance on the ground path, but it's not a huge deal. They'll be relocated in a future iteration. The QFNs have more vias than they need.
