Catania: (bond) faults 2 Modules (30200020035289, …303) fail ARC Fast Tests Low Voltage test: I(V2.50)=804 mA (max 750 mA) Still not understood, but others have appeared elsewhere and also slightly higher currents found also on 4-APV modules In one recent group of 18 modules: 6 anomalous IV curves (detected after bias bond – before readout bonding). Also seen elsewhere.
