Muon Interface MeetingFrontend Board Connection
The fronted board has one full ground layer.
The connection to this ground layer happens on 4 large ground pads on the corner of the chamber

• In order to assure good long term contact of the aluminum parts we will alodine them.
• ‘Alodining is the chemical application of a protective chromate conversion coating on aluminum’
• This procedure is used by the ATLAS MDT system ….
