Hello everyone
On this site AutoQuad team asked to give feedback and help make things better, I assume that it mean that by giving feedback to the team, they can further develope the boards and the software, this is exellent idea. I have no clue about the electric schematics of the boards, so I base only what I see in the pictures on this site.
First of all, what Iv been designing similar boards for 10 years, I'd like to focus to the connectors and their reliability. It appears to be, that connectors are attached to the board only by soldering joint and with SMD pins(?) Machines with motors and vibration, solder does not hold for long, specially when there is a stress pointed to it, in this case a cable and the connector itself, included with vibration. If you have to use SMD-connectors(as I can see you have to due to the double side layout), at least add VIAs to the connector pads or very close proximity, this is not easy if using TH-vias and double side connectors. Best way would be 4 layer microvia-board, but price will go a bit higher.
Second thing is the ESD-protection, do you have any methods on board to prevent ESD-strikes entering the board via cables etc. ? Have you tested your board against ESD and what was the results? Did you make test in temperatures ?
Thanks
