8-Layer Controller PCB
DFM-ready · assembled
Overview
A high-density motion controller board with controlled impedance routing, assembled and functionally tested.
The challenge
Fit CAN-FD, EtherCAT and four motor drivers on a board that had to meet strict EMC limits.
Our solution
Eight-layer stack-up with split power planes, impedance-controlled pairs and a full DFM review before fabrication.
Results
- Passed EMC pre-compliance on the first spin
- Assembled and tested in 10 working days
