2.3.4 Precautions for handling NQ, YQ, SA, and CA
(1) When taking the NQ from the box, press down on the body and take out the sponge first.
(2) Since the pins of the YQ are thin and easily bent, be careful. When inserting it in the NQ, confirm that there are
no bent pins.
(3) When screwing a YQ soldered to a board to the NQ, fasten the screws in four places in turn using a #0 or #1
Phillips precision screwdriver or torque driver after tentatively tightening them. Fix the torque at 0.054 Nm
(MAX.).
If just one place is overtightened, it may cause poor contact. Moreover, a board being connected to the YQ
must have accessory holes in prescribed positions (four places:
φ
2.3 mm or
φ
3.3 mm). The
φ
3.8 mm or
φ
4.3
mm that is the screw head size is an area where wiring is prohibited.
(4) In YQ and SA removal, since there is a possibility of YQ pins being bent or broken when prying and wiggling,
remove them gradually using a flatbladed screwdriver from four directions. Moreover, to connect and use the
YQ and SA, screw the YQ to the NQ according to the YQGUIDE (included with the YQ) using a 2.3 mm
flatbladed screwdriver and then connect it to the SA. Fix the torque at 0.054 Nm (MAX.). If even one place
is overtightened, it may cause poor contact.
(5) For the NQ, YQ, and SA, since there is a possibility that washing fluid on the structure will remain in the
connector, do not perform washing.
(6) NQ, IC, and YQ cannot be used in combination.
(7) A NQ/YQ system cannot be used in an environment of vibrations or shocks.
(8) It is assumed that this product will be used in system development and evaluation. Moreover, when used in
Japan, Electrical Appliance and Material Control Law and electromagnetic disturbance countermeasures have
not been applied.
(9) Since there are rare cases of shape change if the box is left for a long time in a place where it is 50°C or
higher, for safekeeping, store it in a place where it is no higher than 40°C and direct sunlight does not hit it.
(10) For details about handling the NQ, YQ, and SA, see the NQPACK series technical materials at the website of
Tokyo Eletech Corporation.
(11) CA
The CA is an optional product for IECUBE, and can be used to measure the waveform between IECUBE and
the target system.
Since the pins on the CA do not correspond to the pin layout in each device, the pin header cover must be
mounted according to the device to be used. For mounting methods of the pin header cover, refer to URL.
