3.2 Mounting a Mass Production MCU Model
Use the supplied HQPACK to mount the mass production MCU in the user system.
1. Align the index mark on the mass production MCU (●) with the index mark on the NQPACK
mounted on the user system (▲), and then insert.
2. Check that the mass production MCU is correctly inserted into the NQPACK, and then align the
index marks on the HQPACK and NQPACK (angle cut linearly at one place only) and insert
(See Figure 3.3).
As the HQPACK pins are thin and easily bent, check that the HQPACK pins are kept straight
when inserting into the NQPACK.
3. Insert the four screws for attaching the HQPACK into the four screw holes in the top of the HQ-
PACK and tighten the diagonally opposite screws in turn.
Use the dedicated screwdriver supplied with the NQPACK to tighten the screws and tighten each
screw equally in turn. Take care not to over-tighten as this may cause a bad connection.
