Backplane - Characteristics PCB thickness = 2. 2 mm PCB materials = FR 4 Copper thickness = 35µm The draft schematics of the backplane is ready, and with the layout designers support it will be used to optimize the interconnections. The design of the BLEACT including all boards will be done with the CADENCE tool. William Viganò “BLMSPS – Design Overview” 10
BLM connectors in the backplane . . . . BLECF 2 proposal 1 2 3 4 5 6 7 8 • Use RTM space for application-specific backplane • 8 BLM connectors placed in RTM space • Free choice of BLECF 2 connector • The same solution can be used for concentrated LHC BLMs (multiple BLECF 2 boards in a single chassis) – signal BNCs from the back 11

Cards connectors BLEIPU connector Harting: 09 06 115 2911 BLEPSU connector Harting: 09 06 115 2911 No problem if connectors for BLEIPU and BLEPSU are the same, because due to the electronic boxes size, it is impossible to swap them. BLEACC connector (SCEM: 09. 61. 36. 015. 4 Harting: 09 04 132 2921) BLECF 2 connector (Harting: 09 03 164 2921) William Viganò “BLMSPS – Design Overview” 21
Backplane connectors proposal • BLEIPU • free choice, needs to fit within expansion backplane height (~ 63 mm) • DIOT PSU/BLEPSU FCI Pwr. Blade • Harting: 09 06 115 2911 FCI Pwr. Blade would enable the use of standard PSU outside radiation 22
Backplane connectors proposal • Peripheral boards (BLECF 2): • • Air. Max VS to provide power and communication with System Board (BLEACC) o Used in transportation applications o 72 -pin and 96 -pin variants used o Up to 0. 95 A per-pin Harting 09 03 164 2921 proposed by William • Smaller variant can be used on expansion backplane to provide signals from BLM detectors 23

Maintain format of the digital board? ? Might be possible but looks challenging ? M. Krupa “BI-BP future needs for rad-hard tunnel crates” 26
220 mm RF analogue board real estate LHC BPM upgrade Needed Distributed elements. Board dimensions dictated by physics but compact designs could be investigated. 256 mm M. Krupa “BI-BP future needs for rad-hard tunnel crates” 27
LHC BPM upgrade preliminary spec • Real Estate: • • Electrical: • • • 1 unit = 1 digital board + 1 passive analogue RF board Unit size: 3 U might be possible. Is 4 U an option? Typically 2 units per crate 2 x < 50 W power consumption Passive cooling Independent power management per unit Backwards compatibility with FIP No “intelligent” backplane required: • All communication: optical links • BPM signals: RF SMA connectors • Support of a BPM FE unit ID handling? Mechanical: • • Fast and secure installation Simple, easy exchange of BPM FE units M. Krupa “BI-BP future needs for rad-hard tunnel crates” 28
