Mezzanine production status
• 100 ToT mezzanine already produced
– Each mezzanine has two channels
– All of them have been mounted
– To be tested (electric test and burn in)
• Enough to equip more than 5 FEE boards
4
Sum mezzanine
• Sum 4 analog signals
• 10 pieces already produced
• The boards have been mounted
– Needs electric and burn-in tests
5
Voltage regulator production
• Produce ±6V
• 10 pieces in production
– PCB delivery expected in 20 days
– Needs electric and burn-in tests
6
9U motherboard production
• The Gerber files have been sent to the firm
• A first bunch of 5 PCB boards will be
delivered at the mid of June
7
Other equipment
• ToT mezzanine test board
– Used to test the ToT mezzanine before the installation
– Allows to access both PCB sides
• Local thr setting boards
– Used to set the thr in absence of CPU remote
programming firmware
• 9U board front panel
– Prototype already produced
8
Future plans
• Receive and assemble a first full 9U FEE
prototype before the end of July.
• Test the system extensively during fall
• Validate the FEE before the end of November
2011
• Start a first massive production (1/2 of total)
before the end of 2011
