• Electrical Characterisation
  • Operational temperature of 35^oC
  • Operational temperature of 14^oC
• Thermal cycling

Apparatus

• Valencia test box
• Standard mustard VME testdaq and AREO cards
• SCT LV3 with screen connection to Vdd return via 10nF capaciator for all tests
• KEK choke
• Standard twisted pair cable with kitchen foil screen connected at each end to screen connection of D25 plug
• Module Box and Cable Screen connection on AERO patch card connected to Digital Return

All tests performed with the Pseudo-Optical readout chain of the AREO card.

Chiller set to 15^oC for all tests. This corresponded to a temperature of 35^oC on the hybrid. Before kaptons were attached, the DC electrical connection between the hybrid and module box was measured to have a resistance of 0.4Ohms. The module was held on the cooling point with a nut screwed finger tight into place by hand, no torque was recorded.

Note that for the electrical results correction has not been done at present forthe variation in he calibrate capacitor.

During wire bonding of the module glue was spotted on the fan-in over the bond pads. The decission to miss out these channels was taken and thus the module suffers from a very high count of unbonded channels. If these channels are removed the module has only 18 bad channels.

The module underwent 5 cycles from +35^oC to 30^oC inside an environmental chamber, in accordance to the forward QA documentation. The temperture and humidity of the environmental chamber and temperature of the module box were plotted as a function of time. The module was taken to liverpool for surveying and passed the QA tests.
