WP4 Meeting

Glasgow, 13th June 2011

overview
Overview
  • Development of engineering design for stave layout requires knowledge of likely stave core thickness.
  • Components
    • Core Dimensions
      • outer dimensions, bus-tape to bus-tape
    • Core Envelope
      • Twists, bows local ‘roughness’, thermo-mechanical deformations
    • Module-to-tape adhesive
    • Module Envelope
  • Module Envelope
    • Use experience from ABCN25’s with likely extrapolation to ‘final’ ABCN13 modules
abcn25 module z heights
ABCN25 Module Z Heights
  • SmartScope survey of one hybrid glued to a sensor
    • Mount wire-bonding jig on SmartCcope and measure z-height
    • Locate module and establish vacuum
    • Measure z-heights of:-
      • Silicon wafer
      • Hybrid
      • ASICs
      • Wirebonds
      • Capacitors
results
Results
  • Wirebonds
    • Intended difference in loop-height is 0.2mm
    • 4-row wirebonding establishes on LHCbVeLo Beetle ASICs – 0.2mm bond height difference maintained.
    • Expect 4-row ABCN13 wirebonding to be similargiving wirebond height of 0.8mm above ASICs
    • Total height = 1.30 + 0.80 = 2.21mm
  • Capacitors
    • Measured height = 2.17 above local hybrid height of 0.65mm
    • Hybrid unsupported so measured height affected
    • Corrected height = 2.17 + 0.8 - 0.65 = 2.32mm
