6. 6 The radioactive source used for the samples at University of Iowa was Cesium. ASTM E 1250-88 and E 1249-93 was consulted for the testing procedure.

7. 7 NEE001 Used by HERA-B; leading candidate between sensor and HDI Outgassing test: no outgassing detected Irradiation: samples sent to Iowa; most got damaged during the shipping! Wire bonding test: adhesive is soft; wire bonding using K&S 8090 a bit problematic; still working on a solution

8. 8 Young’s modules important property but none of the vendors could provide this information FEA showed that this is the critical parameter in determining the stress on the epoxy. CTE has a relatively minor effect we cannot determine this easily Outside companies contacted
