Hi,

I was looking at the document below and realized that maybe we don’t have to 
even worry about a 6.2 mm height restriction for wiring the Inner cable to 
the T-Board because the inner and outer hybrid “tabs” (page 2 and page 4) 
will be 30mm wide while the V2.1 T-Board will be 70mm wide (page 6) and the 
inner cable conductors will clear the overlap of the two hybrid tab areas.

hi Steve, Mike,
        It looks great to me. Thanks for taking care of this!
        As far as cable direction I guess we would want it to be going 
radially outward from the FST wedge. I don't know how that relates to 
T-board, Zhenyu and Jianing better clarify the orientation for you. I suggest 
not soldering more until it is confirmed.

                Gerard
