Dear all,

As the production starts ramping up, I think we should try to conduct a 
safety review asap to get pre-approval of components/materials that will be 
used in the detector module production soon. These would include all the 
materials to make the detector modules, especially Chroming used to coat the 
cooling tubes, glue/thermal grease used for hybrid/MS assembly at NCKU in the 
next few weeks. We can also include the materials used for APV/Silicon sensor 
assembly as well. 

Shall we also include the other things, such as the T-board, cable, cooling 
tubes?

Zhenyu
