16 Sep 2003CMS Week - Module Production5 Salvatore Costa - Catania FNAL Bonding Bonds are skipped for pinholes (Idiel) and selected cases of Cac. ARCS testing following bonding revealed no new pinholes (17K bonds).

16 Sep 2003CMS Week - Module Production6 Salvatore Costa - Catania FNAL Bonding Sen-to-PA pull test data for odd-numbered modules Units are in grams. RMT PA’s US power adjusted based on results.

16 Sep 2003CMS Week - Module Production8 Salvatore Costa - Catania DB I/F v. 3.0 Added section "Module Pull Tests" for the newly decided pull tests to be performed on bonds made in the PA Test areas, and on a sample (suggested: every 50th) of real PA-Sen and Sen-Sen bonds. Added section on "Hybrid Quality Control " requested by the Strasbourg group. It concerns quality control of the bonds made on Hybrids by the producing Company. Added section on "Hybrid's APV Control Side Bonds Pull Tests" requested by the Strasbourg group. It concerns pull tests on the bonds made on Hybrids by the producing Company. These tests, which are destructive, are done on Hybrids rejected for other reasons and are themselves part of the Hybrid Quality Control process. Removed the check that required Sensor's calibration data (IDIEL, CAC100HZ) to exist in order to serve the "Module Bonding" forms This was decided at the July 2003 Tracker Week, on the argument that bonding all strips is better than not bonding those Modules at all.
