2.3 Mounting and Connecting Connectors (When Using S Type Socket)

This section describes the methods of connecting the QB-RL78L12 and target system.
Make connections with both the QB-RL78L12 and target system powered OFF.
The following abbreviations are used in this section:
- TC: Target connector
- EA: Exchange adapter
- CA: Check pin adapter

Mounting TC to target system

2.3.1
(1) Apply cream solder to the foot pattern of the target system for mounting an IC
(2) There is a circular protrusion (Figure2-4) in middle of the bottom of the TC. The center of this cylinder is a
metallic component (metal plated) for the GND connection. In the same manner as the IC pad, the TC GND is
connected to the target board GND by applying cream solder to the pad in the center of the recommended IC
foot pattern and then reflow soldering.
(3) Soldering condition of TC
(a) Reflow soldering
At 235°C for amaximum of 10 seconds (main heating)
(b) Manual soldering
At 320°C for a maximum of 5 seconds (per pin)
(4) Precautions on flux splatter
If the solder flux splatters when the connector is soldered, faulty contact may occur. Be sure
to cover the upper part of the connector with aluminum foil. Do not clean the connector because the flux
solvent may remain inside the connector.
