Front End Card (FEC)

Here are the dimensions of the FEC board :

The design of the printed circuit of the ASIC prototypes test card has validated the space required for the components and routing in the FEC card : 250 mm x 140 mm. Indeed the minimal value for the length of the board (250 mm) is imposed by the length of the four input connectors plus the gap between the two central connectors (this gap is required by a central mechanical piece of the detector structure). The width of the board (140 mm) cannot be noticeably reduced without causing difficulties in PCB routing.

Below is a picture of a prototype version of the FEC testcard that shows the connectors and gap required to accommodate the T2K central mechanical piece mentioned above.

Front End Mezzannine (FEM)

Concerning the FEM board, it is still in prototype phase so the dimension are not still official. It will be by the end of june.
