B Precautions
1. Recommended Soldering Condition s Flow Condition by Automatic Soldering Unit
Soldering temperature: 250±5?, Soldering time: within 2 seconds
s Manual Soldering Condition
Soldering iron temperature: 290±
10?, 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 the masking tape, etc., and prevent the flux pervasion.
In addition, if much flux is adhered so as to affect the contact, please be sure to clean the board.
3. Cleaning Condition Refer to Nylon Connector Use Hand book.
4. Cautions
s 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.
s If the board deformation could occur due to vibration, please use the gold plating.s Don't use the connector as the top entry.
