Mechanical structure to hold 4 PCBs Minimise inter-sensor spacing Rigid during ~weeks test run Mounting for scintillators above/below 4
sensor stack – on same form factor PCB Minimum sensor separation:
surface mounted components in direct path of sensor (known) + wire bond height (estimated)
fix inter-PCB layer spacing after doing wire bonding
Sensor PCB layout (18/06/2007 Sensor PCB layout (18/06/2007 vintage)vintage)
Sensor PCB layout (18/06/2007 Sensor PCB layout (18/06/2007 vintage)vintage)
Tall components away from square region centred around sensor (direct path of sensor)
Very tall cable connectors outside of central region altogether
Four M3 holes for relative sensor location
Layout in progress
