FYI.

Andy, can you check with John H. to make sure he is aware of this safety 
requirement, and to find out if they have any experience with 
halogen-free PCBs, particularly given the high speed requirements for 
the SRTM.

halogen-free

Hello L2 managers,

As we move closer to making boards, a reminder that everything at Point 
1  should be halogen-free.  So, please verify with vendors that 
materials they supply are indeed halogen-free.  Eg for PCBs: no standard 
FR-4, if megtron-6, make sure you get halogen-free megtron-6 (both 
exist) etc.

Please distribute to the relevant L3s.

Thanks,

Your friendly PO
