6. Mounting Mass Production MCUs
■ Mounting
■ Disconnection
To mount a mass production MCU on the user system, use the supplied HQPACK (IC socket cover)
(see “Figure 6”) .
1. To mount a mass production MCU on the user system, match the index mark (▲) on the NQ-
2. Confirm that the mass production MCU is correctly mounted on the NQPACK. Next, match the
3. Insert each screw for securing HQPACK in each of four tapped holes on the HQPACK, and then
To remove the HQPACK, remove all of the four screws and pull out the HQPACK vertically from
the NQPACK. When taking out the mass production MCU, absorb the mass production MCU using
a vacuum pick-up tool special for removing IC. Do not attempt to remove the mass production MCU
forcibly, for example, using a screwdriver to do so can bend the pins of the mass production MCU
or break the NQPACK.

place only) .
The pins of HQPACK are thin and easy to bend. Insert NQPACK after confirming that pins of
HQPACK are not bent.
tighten the screws 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.
