# # This is the Key In Components File for the # HTM-0 ATLAS L1Calo HTM Card # --------=====----------------------------------- # # Original Rev. 30-Jan-2018 # Most Recent Rev. 30-Jan-2018 # # # Recall that all references to the HTM card will refer to # it in "Standard Orientation". In Standard Orientation # the component side is up facing the observer, the backplane # connectors are to the right, and the front panel is to the left. # # Recall also that the ATCA Standards dimension the board with # respect to the center of the mounting hole in the bottom # left-hand corner, i.e. the SW corner. The center of # this hole is left in X by 3.57 mm from the front edge of # the board and up by 5.55 mm from the bottom edge of the # board. In the HTM card Mentor layout the board's SW # corner will be 0,0 and all dimensions will be in mm. # # Recall also the the shape of the L1Calo ATCA boards is # defined by ARL drawing 1-TE-0183-012-00-B from March-2015 # and does not exactly match the PICMG 3.0 ATCA specification. # # Recall also that the HTM card uses ADFplus Zone 2 connectors. # The locations of these connectors on the PCB is defined in # PICMG 3.1 page 117 (not in PICMG 3.0). # # UNITS MM # # Board_Location # Ref Part_Number Symbol Geometry X Y Properties #----- ----------- ------ ------------------ -------------- ---------- #
