Scanning/Stigmator Signal Distribution Board

A project log for My Custom Scanning Electron Microscope

This is a scanning electron microscope I am building from scratch from mechanical, electronics and control software.

Many signals must be routed to the core of the objective assembly.

There lives the main scanning coils, the aperture imaging coils, and the stigmator octopole

The scanning coils run at high speed when scanning in video mode, so to avoid crosstalking with the stigmator coils the traces routing had to be considered carefully.

A ground plate was introduced to shield the stigmators and the routing was made so that the traces crossing are made perpendicular between each other when the ground plane is not available.
