(2) When mounting device
Caution Check for abnormal conditions such as resin burr or bent pins before mounting a device on the
NQPACK144SD or NQPACK100SD. Moreover, check that the hold pins of the HQPACK144SD or
HQPACK100SD are not broken or bent before mounting the HQPACK144SD or HQPACK100SD
on top of the device. If there are broken or bent pins, fix them with a thin, flat plate such as a
blade.
<1> Make sure that the NQPACK144SD or NQPACK100SD is clean and the device pins are parallel (flat)
before mounting a device on the NQPACK144SD or NQPACK100SD. Then, after mounting the
NQPACK144SD or NQPACK100SD to the target board, fix the device and the HQPACK144SD or
HQPACK100SD (refer to
Figure C-2
).
<2> Using the screws provided with the HQPACK144SD or HQPACK100SD (four locations: M2
×
6 mm),
secure the HQPACK144SD or HQPACK100SD, device, and NQPACK144SD or NQPACK100SD.
Tighten the screws in a crisscross pattern with the screwdriver provided or a driver with a torque gauge
(avoid tightening only one screw strongly). Tighten the screws with 0.55 kg

⋅
cm (0.054 Nm) max. torque.
Excessive tightening may diminish conductivity.
At this time, each pin is fixed inside the plastic wall dividers by the contact pin of the NQPACK144SD or
NQPACK100SD and the hold pin of the HQPACK144SD or HQPACK100SD (refer to
Figure C-3
). Thus,
pins cannot cause a short with pins of neighboring devices.
