2. Confirm that the mass production MCU is correctly mounted on the NQPACK. Next, match the
index mark of HQPACK with the index mark of NQPACK and insert it (angle cut linearly at one
place only). (See Figure 4.)
The pin of HQPACK is thin and easy to bend. Insert NQPACK after confirm that the pin of
HQPACK is not bent.
3. Insert each screw for securing HQPACK in each of the four drilled holes on the HQPACK and
tighten the screw diagonally.
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.
