2.5 Mounting and Connecting Connectors
This section describes the methods of connecting the QB-78K0FX2 and target system.
Make connections with both the QB-78K0FX2 and target system powered OFF.
The following abbreviations are used in this section.
• NQ: Target connector
• YQ: YQ connector
• EA: Exchange adapter
• HQ: Mount adapter
• CA: Check pin adapter
• YS: Space adapter
2.5.1 Mounting NQ in target system
(1) Thinly apply a two-component epoxy adhesive (hardening time at least 30 minutes) to the ends of the four
projections on the base of the NQ and adhere the NQ to the user board (clean the surface of the user board using
alcohol or the like). If alignment of user board pads to NQ leads is difficult, align them as in (2).
(2) Align by inserting the guide pins for alignment for the NQ (NQ-Guide) through the pin holes on the top of the NQ.
Accessory holes are φ1.0 mm non-through holes in 2 or 3 places.
(For hole positions, see the particular NQ drawing.)
(3) Solder after fitting the HQ to the NQ. This is to prevent troubles such as flux or solder splatter and adhering to
the NQ contact pins when soldering.
● Soldering conditions
Solder reflow
At 240°C for a maximum of 20 seconds
Manual soldering
At 240°C for a maximum of 10 seconds (1 pin)
Caution Do not perform washing by flux immersion or vapor.
(4) Take away the guide pins.
24
User’s Manual U17669EJ3V0UM
CHAPTER
2
SETUP PROCEDURE
2.5.2 MountingYQ on NQ
(1) After confirming that there are no broken or bent YQ contact pins, fit the YQ in the NQ and fasten the screw. If
repeatedly inserting and removing, be sure to inspect the YQ pins before fitting. If pins are bent, correct them
using something thin and flat such as the edge of a knife.
(2) Accessory holes are needed in prescribed positions in 4 places in the board for connecting the YQ. Fasten the
YQ to the NQ on the user board using the supplied M2 × 10 mm screws. The thickness of a board corresponding
to these screws is 1.0 to 2.0 mm. Fasten the screws equally in the four corners using a No. 1 or No. 0 precision
(+) driver or torque driver. The tightening torque of the screws is 0.054 Nm (MAX.). Too great tightening causes
bad connections.
Screws for fitting to the NQ (M2 × 10 mm/4) are included with the YQ.
2.5.3 Plugging EA intoYQ
Match the No. 1 pin position of the YQ or YS (C cuts match in both) to the No. 1 pin position of the EA and plug in.
• When plugging or unplugging, press on the NQ, YQ, and YS with a finger so that there is no force on the NQ.
• When plugging or unplugging, be careful of the direction of rocking.
As a tool when unplugging, insert some kind of thin non-conductive material such as a wooden stick between the
YQ (YS) and EA and rock while slowly unplugging. Be careful since the connector will be damaged if this is done
in the wrong direction.
2.5.4 Notes on handling NQ,YQ, andYS
(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 No. 0 or No.
1 Phillips precision driver 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 (4 places: φ2.3 mm or φ3.3 mm). The φ3.8 mm or φ4.3 mm that is
the screw head size is an area where wiring is prohibited.
(4) In YQ and YS removal, since there is a danger of YQ pins being bent or broken when prying and rocking, remove
them gradually using a screwdriver from four directions. Moreover, to connect and use the YQ and YS, screw
the YQ to the NQ according to the YQGUIDE (sold separately) using a 2.3 mm screwdriver and then connect it to
the YS. 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 YS, since there is a danger 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) An 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 YS, see the NQPACK series technical materials at the website of
Tokyo Eletech Corporation.

SETUP PROCEDURE
2.5.5 Notes on mounting NQ and IC
(1) Confirm that there is no weld flash in the resin (sealant part) of the IC. If there is weld flash, remove it using a
knife or the like.
(2) Confirm that there is no weld flash breaking or bending of IC leads. In particular, confirm the planarity of IC leads.
If there is abnormality in the planarity, correct that portion.
(3) Viewing the NQ contact pins from the top, if there are foreign bodies on them, remove them using a brush or the
like.
After confirming (1) to (3), fit the IC to the NQ. Also fit the HQ.
(4) Put the supplied M2 × 6 mm screws in the 4 accessory holes of the HQ and fasten the screws in opposite corners.
At that time, use either the dedicated screw driver that is supplied or a torque driver to fasten them equally in turn
with a tightening torque of 0.054 Nm (MAX.). Since the contact is poor if tightening is too great, once you have
lightly fastened the HQ screws, tighten them again.
(5) Depending on the use environment, when starting up a device that has been left for a long time, starting it may
be difficult. In this case, loosen the screws slightly and then retighten them.
(6) If startup still is difficult after (5) above, check (1) to (3) again.
(7) Tightening the screws of the HQ too much may give rise to cracks in the molded part of the HQ (plastic part) and
bend the mold into a bowed shape, making contact poor.
(8) After soldering the NQ, do not perform washing by flux immersion or vapor.
2.6 Connecting QB-78K0FX2 to Target System
If connecting the emulation probe (QB-80-EP-01T), connect it to the QB-78K0FX2 and the target system by the
following procedure.

(d) Precautions related to emulation probe
The following precautions pertain to using the emulation probe.
<1> Be careful that stress of the emulation probe is not placed on the target connector. Moreover, when
removing the emulation probe, remove it slowly while pressing down on the exchange adapter with a finger
so that there is no stress on the target connector.
<2> Be sure to connect the GND wire of the emulation probe to the QB-78K0FX2 and the target system. If not,
the impedance of the cable becomes unstable, resulting in the lowering of signal transmission
characteristics or distortion of the output waveform for an input waveform.

CHAPTER 4 DIFFERENCES BETWEEN TARGET INTERFACE CIRCUIT AND TARGET DEVICE
This chapter explains the differences between the signal lines of a target interface circuit of the QB-78K0FX2 and
the signal lines of a target device
Although the target device is a CMOS circuit, the target interface circuit of the QB-78K0FX2 consists of an
emulation circuit that depends on the emulation CPU, TTL, CMOS-IC, or other.
When the target system is debugged by connecting it to the QB-78K0FX2, the QB-78K0FX2 emulates just as if the
actual target device were operating on the target system.
However, small differences arise because the QB-78K0FX2 actually is emulating.
