Slide1: C6 fix on Tower A Tracker Flex Cable MRB January 4, 2005 The inner shipping container is opened: The inner shipping container is opened The –Y sidewall of the inner shipping container is removed. The removal of the sidewall begins: The removal of the sidewall begins Short between CLK_M and GND continuously monitored by means of V source/picoammeter connected to the corresponding pins of a breakout box. At the beginning I~0.9 mA for 10 mV input voltage (~10 Ohm). The short disappears: The short disappears Current drops down to ~0.5 nA (~20 MOhm) after the screws on the top-left corner of the sidewall have been removed. The picoammeter is disconnected and the removall of the sidewall is completed. Approximate location of termination resistors Removal of the sidewall is completed: Removal of the sidewall is completed After the sidewall has been removed a quick functional test has been succesfully performed. The tape is applied: The tape is applied Kapton tape is applied *without* disconnecting the cable. Flex cable Foam Resistors Kapton tape Sidewall back in place: Sidewall back in place The sidewall is put back in place (with no solithane on the screws) and the inner shipping container is closed as to begin the CPT – it’s running right now. The process went very smoothly: perfect correspondence between sidwall holes and tray inserts; running torque very low.
