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 conversion
board 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 4-1. Figure 4-1 shows the dimensions of the header board and
conversion board.
