PC boards will be etched and stuffed commerciallyBoards will be measured and debugged on computerized tester before and after burn-in at OSU

Each board will have a unique ID

Board tracking: Microsoft Access

CDF: 50-60 C for 8-24 HrsSufficient for tantalums failuresNo sensitivity to semiconductor

failure

US Military: 125 C for 320 Hrs Chip Makers recommend against this

CFEB: 65 C for 24 Hrs Prove to be effective, not damaging

New Crate Controller DevelopmentNew Crate Controller DevelopmentNew Crate Controller DevelopmentNew Crate Controller Development

A VMEbus Controller with Gigabit Ethernet – A custom board designed and

developed at OSU– Based on XILINX Virtex-II Pro– Customizable firmware.– Optical transceiver (for Gbit Ethernet) – Communicates with stand-alone PC

(in USC55) via Ethernet

Advantages Over Dynatem– No operating system or software on

the controller. All programming done on stand-alone PC in USC55.

– Faster, less expensive: ~ $600 each

Status– PC board produced and stuffed– Firmware being developed
