What we did
- Porting electrical schematics from OrCAD
- PCB layout on principled customer design
- Due to the high complexity of double-checking circuits and component footprints
- Preparing technical documentation to PCBs production
Features of design
- Main boards and expansion boards
- 12 Layers PCB, high density layouting
- Very complex electromagnetic environment on boards
- PCB impedance control
- Combination the large number of independent channels as analog and digital signals, presence of some pulse power supplies on board makes its layout difficult, but interesting task
