■ Connecting
Please mount the supplied NQPACK on the user system before using the LQFP-100P (0.5 mm pitch)
header board.
1. To connect the header board to the user system, match pin 1 indicated by the index mark (▲) on
the NQPACK mounted on the user system with pin1 indicated by the index mark (angle cut lin-
early at one place only in slik screen) on the header board and then insert it (See Figure 4) .
The pin of YQPACK is thin and easy to bend. Insert NQPACK after confirm that the pin of YQ-
PACK is not bent.
2. Insert each screw for securing header board in each of the four drilled holes on the header board,
and then tighten the screws diagonally. The center screw hole is not used.
To tighten the screws, use the special screwdriver supplied with the NQPACK to finally tighten
the four screws in sequence. Tightening the screws too tight might result in a defective contact.
3. Connect the MCU board to the header board while being careful not to excessively force the NQ-
PACK. The MCU board can be connected to the header board only in the correct orientation as
they have an incorrect insertion header socket to prevent reverse connection. Figure 5 illustrates
how the MCU board, header board, NQPACK, and user system are connected together.
