Notes on designing printed circuit board for the user system
When the header board is connected to the user system, the parts mounted around the NQPACK in
the user system may be touched the header board if the height of the parts is tall. To prevent this,
design the printed circuit board for the user system such that the components do not exceed the height
shown in Figure 2. Figure 2 shows dimension
figure of the header board.
