1. SVD Serial Numbers M.Friedl (HEPHY Vienna) 6 May 2014

2. Motivation  We need to identify individual devices  Otherwise, we cannot keep track of each device’s history, test results, location, …  Not everything must be identified  No ID: screws, SilPad, end mounts, …  Wafer only: APVs  Full ID: hybrids, sensors, …  Composite objects (e.g. ladder) get their own ID  <1000 objects of each kind  3-digit number is enough  In the following pages: “000” stands for an ascending number 6 May 2014M.Friedl: SVD Serial Numbers2

3. Objects: Front-End  Hybrids  H6+P000  H6+N000  H6-P000  H6+N000  H3P000  H3N000  Origami  OCE000  O+Z000  O-Z000 6 May 2014M.Friedl: SVD Serial Numbers3  APV wafers (existing serials)  XG4B49T  XH4B48T  XI4B47T  XM4B43T  Pisa sub- assemblies  S+000  S-000  Ladders  L3000  L4000  L5000  L6000  Half-shells  HSL000  HSR000  Detector  SVD000

4. Objects: Electronics  Backplane: BP000  Buffer: BU000  Analog daughter board: AD000  Digital daughter board: DD000  FPGA daughter board: FD000  FADC mother board: FM000  FADC board: FA000  FADC_Controller main board: CM000  FADC_Controller: FC000  Junction mother board  JMP000  JMN000 6 May 2014M.Friedl: SVD Serial Numbers4  DC/DC converter: DC000 (is delivered with non-human readable QR code IDs)  Junction board:  JBP000  JBN000

5. Objects: Composites  Some in the previous lists are composites:  S+000 = H6+P000 + H6+N000 + large_HPK_sensor  S-000 = H6-P000 + H6-N000 + slanted_Micron_sensor  L3000 = 2*H3P000 + 2*H3N000 + 2*small_HPK_sensor  L4000 = S+000 + S-000 + large_HPK_sensor  L5000 = S+000 + S-000 + 2*large_HPK_sensor  L6000 = S+000 + S-000 + 3*large_HPK_sensor  HSL000; HSR000 = lots of ladders  SVD000 = HSL000 + HSR000  FA000 = FM000 + 8*AD000 + 8*DD000 + FD000  FC000 = CM000 + FD000  JBx000 = JMx000 + 8*DC000 6 May 2014M.Friedl: SVD Serial Numbers5

6. ID Tags  Preferable: human readable + machine readable  Sensor: no tag  Other items: printed sticker (OK with 10MRad)  Little space on some objects  Brother QL-720NW label printer  Smallest sticker: 12mm wide  HEPHY can provide tags for all objects 6 May 2014M.Friedl: SVD Serial Numbers6

7. ID Tag Example  Hybrid Board  Text + CODE128  Sticker: 35 x 4.5 mm 2 (involves manual cutting)  Most other objects are less critical regarding available space  Except: Analog & digital daughter boards probably allow hand writing only 6 May 2014M.Friedl: SVD Serial Numbers7
