2. 5 Mounting and Connecting Connectors
This section describes the methods of connecting the QB-78F1026 and target system.
Make connections with both the QB-78F1026 and target system powered OFF.
The following abbreviations are used in this section:
- TC: Target connector
- YQ: YQ connector
- EA: Exchange adapter
- MA: Mount adapter
- CA: Check pin adapter
- SA: Space adapter
2.5.1 Mounting TC to 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 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).
(2)
Align by inserting the guide pins for alignment for the TC (NQGUIDE) through the pin holes on the top of the
TC. Accessory holes are φ1.0 mm non-through holes in two or three places.
(For hole positions, see the particular TC drawing.)
(3) Solder after fitting the MA to the TC. This is to prevent troubles such as flux or solder splashing and adhering
to the TC contact pins when soldering.

Caution Do not perform washing by flux immersion or vapor.
(4) Take away the guide pins.
