Notes on Using Narrow Pitch Connectors

This section provides critical safety remarks and usage guidelines for narrow pitch connectors, designed for board-to-board and board-to-FPC applications. Adhering to these notes is essential to prevent accidents, injuries, and product damage.

Key Usage Guidelines:

• Safety First: Never use connectors beyond their specified limits (rated current, dielectric strength, environmental conditions). Exceeding these can lead to abnormal heating, smoke, and fire.
• Specification Review: Thoroughly review specifications before use. Contact a sales representative for any usage outside of defined parameters. Panasonic Corporation cannot guarantee quality and reliability for non-compliant usage.
• Continuous Improvement: While Panasonic strives for quality, electrical components have inherent failure probabilities. Durability varies with usage environments. Test components under actual conditions and implement safety designs (redundancy, fire spread prevention, malfunction prevention) to mitigate risks.
• Board-to-Board Design: Avoid connecting a pair of boards with multiple connectors to prevent misalignment, mating failure, or product breakage.
• PC Board Pattern Design: Account for mounting equipment positioning errors (up to 0.2-0.3 mm). Design PC boards and patterns considering equipment performance.
• Positioning Tabs: If connectors have embossed tabs for positioning, ensure PC boards have matching positioning holes.
• Soldering Strength: Design PC board patterns according to recommended dimensions to ensure mechanical strength when soldering terminals.
• PC Board Thickness: Minimize the thickness of cover lay and adhesive to prevent poor soldering, as these connectors have no stand-off.
• PC Board Fixation: For narrow pitch connectors, design means to fix the PC board in place (e.g., with screws and spacers) to prevent detachment during vibrations or impacts.
• FPC Mounting: When soldering connectors to FPCs, consider using a reinforcing plate on the backside of the FPC to prevent solder detachment due to force on terminals during mating/unmating.
• Temporary Locking: Some connectors have temporary locking structures. Consider measures to prevent mating separation due to dropping impact, especially with larger or heavier FPCs.
• Handling: These connectors are compact and thin. Handle with care during mating to prevent displacement, angled mating, damage, or deformation.
