6. Mounting Mass Production MCUs
To mount a mass production MCU on the user system, use the supplied HQPACK.
■
Mounting
1. To mount a mass production MCU on the user system, match the index mark (
▲
) on the NQ-
PACK mounted on the user system with the index mark (
●
) on the mass production MCU.
2. Confirm that the mass production MCU is correctly mounted on the NQPACK, and then align
the indexes of the HQPACK with the NQPACK (the corner that has a straight-line notch cut out
of it) and insert the HQPACK into the NQPACK (see “Figure 5”).
The HQPACK pins are thin and easily bent. When you are connecting the HQPACK to the NQ-
PACK, ensure that the HQPACK pins are not bent before pushing it all the way into the NQ-
PACK.
3. Insert the screws for securing the HQPACK into the four holes in the HQPACK, and then tighten
the screws in the opposite corners evenly using the special screw driver that was included with
the NQPACK. Be careful not to over-tighten the screws as this may result in bad connections.
