Andy Blue Glasgow Update
2
Andy Blue WP3 Meeting Summary ESD Protection –Part all arrived and installed Compressed Air Controls –New lines and panel being installed in following 2 weeks Testbeams –Recon software, & Organising workshop (DESY) Strips DCS –Control via SCTDAQ of HV & LV Temperature Interlock Patterned ASICs –Planning of wire bond trials
3
Andy Blue WP3 Meeting Cleanroom We have a class 10k cleanroom –Signed off as class 1k Contains –Dicing saw –2 Probers –2 wire bonders We also have a “semi-clean” room –Contains Module/Gluing Assembly In 3 Laminar Air Flow Cabinets –HSIO setup –Glue robot –Pick & Place machine –Metrology System
4
Andy Blue WP3 Meeting ESD Very wary of having procedures in place for ESD protection for module assembly and testing –For both rooms –For all parts of the build and assembly process There is no point in having ESD floors if other ESD procedures are not carri ed through with –Much like cleanliness
5
Andy Blue WP3 Meeting ESD Grounding Wrist Strap Attaches to wrist of user Our system is 1 wrist strap / cleanroom user And not 1 /station Each user is responsible for their own wrist strap
6
Andy Blue WP3 Meeting ESD protection for Tables Attached to tables in clean room Allows connection to wristband via cord to ground Allows you to adapt tables to be grounded
7
Andy Blue WP3 Meeting Wristband/Heel Grounder Test Station Attached to wall of clean room Allows you to test the wristband and footwear for ESD protection
8
Andy Blue WP3 Meeting ESD Floor tester Can check that ESD floors are properly bonded to earth –Calibrated to 200 Mega Ohms Dynamic –User (wearing ESD footwear) walks on floor Static –A weight is applied to the floor and directly tested
9
Andy Blue WP3 Meeting Using the Floor Tester Dynamic (i.e. Shoes work)Static (i.e. Floor works)
10
Andy Blue WP3 Meeting Detector Control System To prepare for the 130nm, work, wanted to complete the DCS (detector control system) for testing of hybrids and modules High Voltage: Keithley 2410 Low Voltage: TTi TSX-P Series Fan cooler + LVDS Buffer board: Agilent E364X Cambridge Temperature Interlock Box
11
Andy Blue WP3 Meeting Temp Interlock box First set up using Arduino software –Serial monitor –Connect Interlock by USB Addressed settings for Hybrid NTCs CommandSetting htl,10All Hybrid NTC's lower temp to 10 deg hth,40All Hybrid NTC's higher temp to 40 deg hne,22 Hybrid NTC's enabled hna,22 samples for averaging filter on Hybrid NTC reading hrn,10Nominal Hybrid NTC Resistance (at Nominal Temperature) is 10 kOhm htn,25Nominal Hybrid Temperature is 25 Deg hbn,3435NTC B parameter is 3435 K
12
Andy Blue WP3 Meeting Compilation + ROOT Next step is to control via SCTDAQ (ROOT) When compiling sctdaq_HSIO –‘Add Existing project –./sctdaq/interlock/tilokl.vcproj –Compile as usual –Should produce a./sctdaq/interlock/tilockdll__/ folder –Also creates.dll files in./sctdaq/bin From ROOT –Run ‘gSystem.Load(“./sctdaq/bin/tilockdll.dll") –This initiates the TILock class –locker = new TILock("ASRL**::INSTR") –** =number of COM port USB cable is attached to –In my case it was locker = new TILock("ASRL4::INSTR") Began to integrate into RootLogin.C
13
Andy Blue WP3 Meeting LV + HV High Voltage –Can automate from ROOT (using 2410) Sensor High Voltage Ramping IV scan Plotting of graphs Low Voltage –ABCn250 powering (TTi) 2.5V & 4A –Fan cooler & LVDS buffer card (Agilent) Using Labview
14
Andy Blue WP3 Meeting As of Today Interlock box switched off HV supply (in reality will be LV) after pt100 attached > 30 o C Wired up interlock box to DC-DC Module to monitor actual hybrids (Test later today)
15
Andy Blue WP3 Meeting Patterned ASICs Wafer 72 Patterned Glass ASICs Bond pads on all 4 sides
