Oxford QAQC meeting testiranje bondiranja na 100 bondih

Oxford QA/QC meeting

• testiranje bondiranja na 100 bondih na vsakem tapeu (cca 800 tapeov) • Zahteve: utržna sila več kot 8 g, sigma manj kot 1. 5, noben manj kot 5 g • testiranje HV toka na kablih manj kot 20 n. A, enako kot na SCT kablih • QA senzorjev še ni točno definiran

• Meritev atenuacije: 4. 8 d. B (specifikacija manj kot 15 d. B)

Obljube senzor QA: • It is true, we can irradiate several small (about ten, maybe even more) samples to the same fluence in one irradiation. We could do 1 -2 regular irradiation campaigns per month, irradiating miniature sensors to 4 different fluences in the each campaign. A simple count - If we have 12 batches per month, even one proton and neutron fluence means 24 CCE measurements per month if we want to do test on the batch basis. Many shipments and a lot of CCE measurements. Currently we have to provide (and pay) gamma spectroscopy for every shipment. . . • CCE: these take much more time to us, we are limited with technical support. 1 measurement per week is absolute maximum on few month scale, for several years program it is probably too much.
