Robotic PCB 24V Motor Drive Board

This project involves the design and manufacturing of two critical printed circuit board assemblies (PCBs) for a next-generation robot control system: a 24V Motor Drive Board. These assemblies form the core of the robot’s motion control and I/O connectivity infrastructure.

24V Motor Drive Board
Layer Stackup: 6-layer FR4 construction
Copper Weight: 2 Oz on outer layers, 1 Oz on inner layers
Surface Finish: ENIG (Electroless Nickel Immersion Gold)
Solder Mask & Silkscreen: Blue solder mask with white silkscreen on top and bottom
Impedance Control: 50 Ohm single-ended and 90 Ohm differential impedance control
PCB Thickness: 1.6 mm target
Material: High Tg 170+ FR4 for enhanced thermal stability
Quantity: 10 units

This board is responsible for driving the robot’s 24V motor systems, requiring robust power delivery and precise signal integrity. The high Tg material ensures reliable performance under elevated operating temperatures, while impedance control maintains signal quality for high-speed communication interfaces.
