OPEN ISSUES & SUMMARYOPEN ISSUES & SUMMARY 2 QM IF1 high units delivered December 2003 (EQM2 & EQM4) 2 QM IF1 high units being qualified (EQM1 & EQM3) QM IF1 low: Structures and Substrates being fabricated 4 QM isolators measured Qualification boards done and qualified FM IF1 High:
Structures being fabricated (problems with type of aluminium) Substrates being fabricated
FM IF1 Low: Structures and Substrates to be fabricated once the QM units are
tested Uncertainties about the performance of the IF1 low fabricated by Alcatel Alcatel delays very difficult to recover
