5. MOUNTING MASS PRODUCTION MCUs
Use the supplied HQPACK to mount a mass production MCU on the user system.

Mounting
1. Align the index mark (

) on the NQPACK mounted on the user system with the index mark (
●
)
on the mass production MCU and mount the MCU on the NQPACK.
2. Confirm that the mass production MCU is correctly mounted on the NQPACK and then align the
index mark on the HQPACK with the index mark on the NQPACK (the corner with an angle cut
out of it) and insert the HQPACK into the NQPACK (see Figure 5).
The HQPACK pins are thin and easy to bend. Check that the HQPACK pins are not bent before
inserting it into the NQPACK.
3. Insert each of the screws for securing the HQPACK into the four holes in the HQPACK, and then
evenly tighten the diagonally opposite screws in turn using the special screwdriver that was in-
cluded with the NQPACK. Be careful to avoid overtightening the screws as this may cause a bad
connection.
