Format noch korrigieren2Need for an automatic productionAHCAL (final design)About 8.000.000 tiles have to be placed on HBU boardsWith an effort of 10 s per tile ~ 8 years are necessary for the assembling We need an automatic placement With 1 second per placement we need 1 year

3 companies have confirmed, that vision system can handle the tiles

Mass AssemblyCurrent designMounting of tile on HBU board:Tiles have to been pushed into the alignment pin holesVery small tolerances are needed to fitWith 4 pins (2 SiPM pins, 2 allignment pins), tolerances have to be quite big
