Mounting Mass Production MCUs

Mounting
To mount a mass production MCU on the user system, use the supplied HQPACK (IC socket cover)
(see “Figure 6-1”) .
1. To mount a mass production MCU on the user system, match the index mark (
▲
) on the
NQPACK 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. Next, match the
index mark of HQPACK with the index mark of NQPACK and insert it (angle cut linearly at one
place only) .
The pins of HQPACK are thin and easy to bend. Insert NQPACK after confirming that pins of
HQPACK are not bent.
3. Insert each screw for securing HQPACK in each of four tapped holes on the HQPACK, and then
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.
