A turret test-point carrier PCB for the ECEN 442 DSP motor-control lab. Top and bottom ground pours are tied together with stitching vias. I also designed a holder for the board in SolidWorks.
The project is finished. The fabricated boards are assembled and mounted in their holders for the lab benches.
I also repair the lab's motor test benches. I trace each fault to its root cause, do SMT and through-hole rework, and run functional tests with Code Composer Studio on a TI C2000 to confirm the fix.
