Notes on Using Narrow Pitch Connectors

These notes provide essential safety remarks and guidelines for using narrow pitch connectors, particularly for board-to-board and board-to-FPC applications. Adhering to these instructions is crucial to prevent accidents, injuries, and product damage. It is recommended to review specifications thoroughly and consult sales representatives for usage outside of specified parameters. Panasonic Corporation strives for continuous quality improvement, but electrical components have inherent failure probabilities. Users should verify actual component performance under real-world conditions and implement safety designs such as redundancy, fire spread prevention, and malfunction prevention to mitigate risks associated with component failure or end-of-life.

Key Usage Considerations:

• Safety Remarks: Do not exceed specified ratings (current, dielectric strength, environmental conditions) to prevent abnormal heating, smoke, or fire. Thorough specification review is mandatory.
• Board-to-Board Design: Avoid connecting a pair of boards with multiple connectors to prevent mating failure or breakage due to misalignment.
• PC Board Design: Account for mounting equipment positioning errors (up to 0.2-0.3 mm). Design PC boards and patterns considering equipment performance. Utilize positioning holes if connectors have embossed tabs. Ensure PC board pattern design dimensions meet recommended mechanical strength requirements for soldering. Minimize cover lay and adhesive thickness to prevent poor soldering, as connectors may lack stand-offs. Implement means to fix PC boards in place (e.g., screws) to prevent detachment during vibration or impact.
• FPC Mounting: Reinforce the backside of the FPC where the connector is mounted with a reinforcing plate to prevent solder detachment during mating/unmating. Consider measures to prevent mating separation caused by dropping impact, especially with FPC size, weight, or bending force.
• Handling: Due to their compact and thin design, take care during mating to prevent displacement or angled mating, which could damage or deform the connector.
• Placement Machine & Mounting: Select placement machines considering connector height, accuracy, and packaging. Be aware that excessive chucking force can deform the connector body or terminals. Avoid applying external forces to contact surfaces during mounting. Use automatic positioning machines for accurate mounting if self-alignment is insufficient.
• Soldering: Follow recommended reflow soldering profiles. Use screen printing for cream solder. Ensure proper screen opening and PC board foot pattern areas. Avoid excessive solder to prevent mating interference. Adhesives may be needed for connectors mounted on the underside of double-sided PC boards. Consider solder/flux characteristics and reflow temperature/oxygen levels. Use pure water passed liquid solvent for cleaning if necessary.
• Hand Soldering: Adhere to specified soldering iron temperatures and durations. Avoid flux spreading onto connector leads or PC boards. Apply solder wire to the foot pattern after heating. Do not apply load during soldering. Clean soldering irons thoroughly. Check and clean contact surfaces after soldering.
• Solder Reworking: Finish rework in one operation. Do not use supplementary solder flux for rework. Keep soldering iron tip temperature below specified limits.
• Single Component Handling: Handle with care to avoid dropping or excessive force on terminals, which can cause warping or weaken solder adhesion.
• Cleaning Flux: No cleaning is generally required. If cleaning, use clean solvents and prevent contamination of contacts. Pure water passed liquid solvent is recommended.
