<pre>Hi Elton,
The additional readout layer (1-2-3-4 compared to the old 3-3-4) fits on
the board. The layout is tight on the inner section of the PCB but this
was expected.
The other good news is that I went ahead and performed the layout of
most of the board as this was necessary to fully determine the impact of
this addition. All the components had to be re-arranged due to this
addition and to the new cold plate/light guide and U-board cable assembly.
Best regards,
Fernando
