4. PCB #RO/PCB – Manufacturer and QC files: Relative position of strips wrt rasmasks/targets Rectitude and parallelism of strips Pillar height Thermal cycles Resistivity Other defect (bubbles, …) – Parameters: PCB thickness Cuts, shorts Precision holes (position, circularity, …) – Dependencies: #WASHER (for PCB positioning) #D/PCB – Manufacturer and QC files – Parameters: PCB thickness #WASHER -Manufacturer and QC files -Parameters: -Position / strips

5. Panels #RO/PANEL – Manufacturer and QC files – Parameters: Planarity Parallelism Thickness Strip alignment side/side – Dependencies: #RO/PCB, #IC, #FRAMES, #INSERTS, #PIN, #COOLING, (…) #D/PANEL (with mesh) – Manufacturer and QC files – Parameters: Planarity, Parallelism, Thickness Drift distance Mesh frame thickness – Dependencies: #D/PCB, #IC, #FRAMES, #MESH, #GAS/T, (…)

6. Quadruplet #MODULE – Manufacturer and QC files – Parameters: R/O strips alignment Gain homogeneity / plan Cosmic rays test Assembly scheme (panels order) Thickness and parallelism (?) – Dependencies: #DGAP, #ORING, #SCREW, #IC/ENDCAP, …

7. Components (parameters) #IC – Thickness #IC/ENDCAP #FRAMES – File: position in the panel – Parameters: Thickness, Twist #MESH – Tension (on transfer frame) #COOLING/TUBES (like #FRAMES) #TAPE – Lot number #GLUE – lot number – Expiration date #GAS/T – Lot number #WASHER #INSERT (and #PIN) – Position, perpendicularity, diameter, … #THERMAL/INS – Lot number #ZEBRA/POS #COOLING/PLATE #DGAP – Lot number – Thickness – Corners ID #ORING #SCREW

8. Files Assembly check list and notes Version of drawings List of operations (procedures and controls) Problems, defects and decision process Quick access parameters Specifications Delivery receipt (if available) Logistics information (time dependent)

9. Include in DB the integration phase: – Elx – Alignment platforms – Mounting on wheel – … Module localization and on-going activities Definition of ID: – Size of the piece – Bar code? – Batch of pieces (screws, glue, oring, …
