  1. DC56 Bi-weekly Meeting:DC5 Modifications September 3, 2013 Robert Heitz University of Illinois

  2. 64 More Channels per Layer Color Coding G-10 -> Green PCBs -> Grey, Red, Gold • Grey PCBs are not modified • Red PCBs are modified on the edges • Gold PCBs are new

  3. PCB Modified Edges Straight Edge Slanted Edge Before After Originally end PCBs had straight edges. Additional PCB require previous end boards to have a slant connection.

  4. PCB Modified Edges Slanted Edge

  5. Side View of Modified DC5 UU’ VV’ Modified Side

  6. Copper Shielding Modifications • Additional PCBs extend out past G-10 and require shielding to be modified. New PCBs and read out electronics require additional cuts on copper shielding.

  7. Additional Soldering Cuts • Soldering cuts must extend around G-10 frames. Original Soldering cuts More soldering cuts must be made here to account for new PCBs

  8. Soldering Cuts • Using the same soldering cuts as DC4 causes high voltage cuts to be through holes. • This means high voltage cuts must be shallower. • Gas cuts must also be modified in this region. Beam killer cuts must not be as deep. Soldering Cut
