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