6. Mounting Mass-production MCUs
I Mounting
In order to mount a mass production MCU on the user system, use the HQPACK064SB140 which is
supplied with the product.
1) To mount a mass production MCU on the user system, match the index mark (L) on the
NQPACK064SB mounted on the user system with the index mark (G) on the mass production
MCU.
2) Confirm that the mass production MCU is correctly mounted on the NQPACK064SB. Next, insert
the HQPACK064SB140 into a NQPACK064SB (see Figure 5).
The pin of HQPACK064SB140 is thin and easy to bent. Insert NQPACK064SB after confirm that
the pin of HQPACK064SB140 is not bent.
3) Insert each HQPACK064SB140 screw for securing in each of four tapped holes on the
HQPACK064SB140, and then first tighten the screws in opposing corners followed by the two
remaining screws.
To tighten the screws, use the special screwdriver supplied with the NQPACK064SB to finally
tighten the four screws in sequence. Tightening the screws too tight might result in defective
contact.
