QB-RL78G1F In-Circuit Emulator
2.4 Mounting and Connecting Connectors (When Using T Type)
This section describes the methods of connecting the QB-RL78G1F and target system.
Make connections with both the QB-RL78G1F and target system powered OFF.
The following abbreviations are used in this section:
- NQ: Target connector
- YQ: YQ connector
- EA: Exchange adapter
- MA: Mount adapter
- CA: Check pin adapter
- SA: Space adapter
2.4.1 Mounting NQ 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 NQ and adhere the NQ to the user board (clean the surface of the target system
board using alcohol or the like). If alignment of target system pads to NQ leads is difficult, align them as in (2).
(2) Align by inserting the guide pins for alignment for the NQ (NQGUIDE) through the pin holes on the top of the
NQ. Accessory holes are φ1.0 mm non-through holes in two or three places.
(For hole positions, see the particular NQ drawing.)
(3) Solder after fitting the MA to the NQ. This is to prevent troubles such as flux or solder splashing and adhering
to the NQ contact pins when soldering.

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