6. 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.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. 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.

Disconnection

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.
