2.5.2 Mounting YQ to TC
Mounting and Connecting Connectors
(1) Thinly apply a two-component epoxy adhesive (hardening time at least 30 minutes) to the ends of the four
(2) Align by inserting the guide pins for alignment for the TC (NQGUIDE) through the pin holes on the top of
(3) Solder after fitting the MA to the TC. This is to prevent troubles such as flux or solder splashing and
(4) Take away the guide pins.
(1) After confirming that there are no broken or bent YQ contact pins, fit the YQ in the TC and fasten the screw.
(2) Accessory holes are needed in prescribed positions in four places in the board for connecting the YQ.
This section describes the methods of connecting the QB-179F124 and target system.
Make connections with both the QB-179F124 and target system powered OFF.
The following abbreviations are used in this section:
projections on the base of the TC and adhere the TC to the user board (clean the surface of the target
system board using alcohol or the like). If alignment of target system pads to TC leads is difficult, align
them as in (2).
the TC. Accessory holes are φ1.0 mm non-through holes in two or three places.
(For hole positions, see the particular TC drawing.)
adhering to the TC contact pins when soldering.
Caution Do not perform washing by flux immersion or vapor.
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.
Fasten the YQ to the TC on the target system using the supplied M2 x 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 #0 or #1 Phillips precision screwdriver or torque driver. The tightening torque of the screws is
0.054 Nm (MAX.). Too great tightening causes bad connections.
Four screws for fitting to the TC (M2 x 10 mm / 4 units) are included with the YQ.
