IOP : LHCb Scintillating Fiber detector front end electronics design and quality assurance

The on-detector electronics of the LHCb Scintillating Fiber Detector consists of multiple PCBs assembled in a unit called Read Out Box, capable of reading out 2048 channels with an output rate of 70 Gbps. There are three types of boards: PACIFIC, Clusterization and Master Board. The Pacific Boards host PACIFIC ASICs, with pre-amplifier and comparator stages producing two bits of data per channel. A cluster-finding algorithm is then run in an FPGA on the Clusterization Board. The Master Board distributes fast and slow control, and power. We describe the design, production and test of prototype PCBs.
