Summary of discussion:

Metallisation on dummy LAS and AncAsic would be preferable.

Dummy AncAsic made of glass substrate with metallization should achievable: 300um thickness. But is the form factor of 15mmx1.5mm going to be an issue for dicing?

Dummy LAS: is it possible to get it made of glass ~50um thick?
(EPIC will procure dummy Si wafers with metallization, mainly for MOSAIX, any portions of this wafers that could be used for our OB module prototyping?)
