Sumario:The precise and lightweight Vertex Locator (VELO) - a LHCb sub-detector - modules are built to position the sensors at the closest possible distance to the beamline while providing mechanical support, cooling, high voltage, ultra high speed data links and all electrical services in such a way that adds minimum material in the LHCb acceptance. The assembly of one of the double sided VELO modules requires precision glueing of the pixel sensors and hybrids onto the delicate microchannel surface followed by wire bonding, cable attachment and metrology.
