Update

• ABCn130– Dicing and FIB work– Wire bond trials– Bonding program v3

• X-ray imaging of Glue Coverage• Spending

– Cabinets

• ATLAS12 measurements– Analysis software

ABNc 130

• First ABCn chips are now with FIB group– Remainder of chips to be diced

• 30 for FIB

• Remainder for wire bond trials

– Plan is to hand out to groups at AUW• As well as Glass ASICs

130nm Bonding Parameters

• 2nd Wire bonding trials began– Using back to back abcn130 chips

• Separated by 1.5mm to allow 30o angle with 500um bond loop height– used chips from periphery of wafer

• Bonds to go down next few days– Will look at the lower bond forces suggested at last meeting

QA - Wire bonding Programs

• Now have a range of programs for wire bonding QA– 250nm Barrel

• Hybrid work

– V1 : Records bond number and fault

– V1.2: Records bond number and tells user info

on bond

• Module Work– 130nm Barrel

• Hybrid Work V3 finished last week•Able to cope with

Different hybrids and modules for both endcap and barrelDifferent bond programs for different institutions

•User chooses appropriate .h file for usage

QA – SVN repository

• As of last have SVN account at CERN• Means anyone can download the version they want• Can play with/optimise code• Will let others know when ready to download from

• Can use same area for other code (eg vac monitoring)

• Had this idea for a while – Use the Medipix chip to X-ray the ASIC gluing– Images taken of Module via Bart over various areas

• 60Kev (Vp) X-rays with 1s acquisitions

Medipix Hybrid Pixel Detector

• 65k single-photon counting pixel array;

• Square pixel size of 55 µm;

• 14x14 mm area;

• Electron or hole collection;

• Threshold equalisation;

• Count rate of ~100 kHz;

• Readout in 300 µs;

• High dynamic range;

Medipix/Timepix

X-ray Imaging – ASIC Gluing

• Scanned glued hybrid on Module (from Bart)

• Very clear Imaging of glue spots

• Rough analysis shows glue coverage of 39%

• Good for• Sanity check• Initial 130nm glues?

BCC on Module

• Imaging of BCC on the module

• Tuning “should” allow me to see the module to hybrid glue as well

• We also have an automated stage that can be used to raster scan a full module

Spending

• Dry storage cabinets – Delivery dates of Tue 25th and Wed 26th March– FAO Cambridge & RAL to successfully receive these as a

Glasgow order I need a scan of the delivery confirmation from your sites

• Almit ran out of component for model ordered– “The original HSD-1106-51 had a basic control unit and display but it has been replaced with

a SIEMENS display and controller (that has been used on more expensive Totech cabinets for about 5 years) that makes the dry unit operate more efficiently …..and operates in a SMARTER way…”

– “it dries faster (recovers quicker) after door openings and holds the RH set point more accurately…so the performance is better…”

– “They should be sold at a higher price…but yours prices won’t change.”

ATLAS12 measurements

• Fixed Analysis code– Returns correct (bad) CCE from irradiated sample under test– Writing additional code that plots measurements from multiple

files for given sample • E.g. CCE measurements for varying voltage and automatically

plots in ROOT

Example of code in testbeam reconstruction

Plots cluster size from various input files
