Right-angle Through-hole Terminals, with Fastening Pin

Precautions

■ Correct Use

Mating Compatibility

XH3 Half-pitch Connectors do not mate with XH2 or XH4 Half-pitch

Connectors.

Special Finish for Preventing Flux Rise

XH3 Connectors (i.e., Straight Terminals and standard size, 1-, and

2-mm increments) have a special finish that prevents flux rise. (The

Connectors are designed for automated soldering. Brush coating flux

from the back of the board applies too much flux and may nullify the

special finish. Never use this method to apply flux.)

Soldering

Automated soldering

Use tape to mask the Right-angle Terminal Connector prior to

automated soldering.

Automated Soldering Conditions (Jet Flow)

1. Soldering temperature: 250±5

°C

2. Continuous soldering time: Within 5 s (Be sure to wash the board

after continuous soldering is completed.)
