Precautions for Use
1. Recommended Soldering Condition
Flow Condition by Automatic Soldering Unit: Soldering temperature: 250±15°C, Soldering time: within 2 seconds
Manual Soldering Condition: Soldering iron temperature: 290±10°C, Soldering time: within 2 seconds
2. Board Masking
If the automatic soldering unit is used, block the pin header through-hole on the receptacle mounted board with masking tape, etc., and prevent flux permeation. If flux adheres excessively and affects contact, clean the board.
3. Cleaning Condition
Refer to Nylon Connector Use Handbook.
4. Cautions
- It is impossible to fix the board to the board by the connector only. Please take actions to fix the board without using the connector.
- If board deformation could occur due to vibration, please use the gold plating.
- Do not use the connector as the top entry.
