Power conductor ampacity: 1 Amp (estimated, as this is a power limited cable)

Power conductor overcurrent protection: sense lines are connected to load using (50W )

current-limiting resistors. This would limit current to 160 mA in the event of a short in the sensing circuitry on the power supply.

High voltage conductor rating: 150V

SVXII Junction Board Cable Connector

Manufacturer: Custom designed at UNM. Vendor for fabrication TBD.

Board type: Multi-layer PCB

Part number: n/a

Function: Merges power and timing signals from the SVXII power supplies and FIB transition module onto the SVXII Long Cu-Kapton cable

Dimensions: approximately 2.5 x 3.5 inches (TBD).

Location_1: Just inside the ISL space frame.

Connector_1: 5 input connectors and 2 output connectors. See the technical design specification for a complete description.

Comments: Keyed and/or D shape connectors prevent incorrect connector mating.
 
 

Flame test rating:

Substrate Material: G10
 
 

Note: The specification of this board has been provided to the committee, and can be found on the web at http://www-cdf.fnal.gov/upgrades/svxii/power/junction2.html.

The design of traces on the board exceeds the current carrying abilities of the connector pins. In cases where the connector receptacle on the junction board supports less current than the cable conductors, the maximum current listed for the respective cable has been adjusted to reflect this.

Connector pin-out assignments: (See specification for details)

Power conductor overcurrent protection: fused at power supply (as well as hardware and software trip protection).

High voltage conductor rating: High-voltage traces are separated by at least 0.010 inches from all other traces. This will withstand a voltage of up to 500 V, per IPC guidelines.

Other traces are separated by at least 0.005 inches, which will withstand up to 100 V.

SVXII Long Cu-Kapton Cable

Manufacturer: Custom designed at Fermilab. Vendor for fabrication TBD.

Cable type: Cu-Kapton flex cable

Part number: n/a

Function: Delivers power and timing signals from the SVXII junction board to the SVXII pigtail cable.

Length: 4 ft.

Location_1: At junction board, just inside ISL spaceframe.

Connector_1: Two (2) Berg Electronics 91910-21141, high-density "Conan" connectors

Location_2: SVXII pigtail cable

Connector_2: Two Berg Conan connectors, 91910-21141

Comments: Keyed connector prevents incorrect mating.
 
 

Flame test rating: service temperature rating of 300 ° C; negligible burning rate per ASTM 635.

Insulation material: Kapton (polyimide)

Jacket material: none
 
 

Note: This cable follows the design specification of the pigtail cable, which has been provided to the committee, and can be found on the web at

http://www-cdf.fnal.gov/upgrades/svxii/power/pigtail_spec.html. Relative to the pigtail design, this cable is twice as long, but all current-carrying traces have been widened by factors of 5 to 9. Thus this cable has an even higher electrical safety margin than the pigtail cable.

Power conductor ampacity: 0.3Amp (the connector capacity has been derated by 2/3, because there are multiple pins for some output lines).

Power conductor overcurrent protection: fused at power supply (as well as hardware and software trip protection).

High voltage conductor rating: High-voltage traces are separated by at least 0.015 inches from all other traces. This will withstand a voltage of up to 300 V, per IPC guidelines.

Other traces are separated by at least 0.005 inches, which will withstand up to 100 V.

Connector rating is 50 V, so pins 23,24,27,28 have been left unoccupied. Tests at LBL showed no leakage over 24 hours for a voltage difference of 200 V.
