Essential Design Factors for Durable Connections

When designing board-to-board connections, engineers must first consider several critical factors that directly impact connector longevity. First and foremost, proper contact design ensures reliable electrical connections. Moreover, mechanical stability plays a crucial role in preventing connection failures.

Common failure points include:

• Contact wear – Often results from repeated mating cycles
• Environmental degradation – Caused by exposure to moisture and contaminants
• Mechanical stress – Due to vibration and thermal cycling

Material Selection Guide

Choosing the right materials is fundamental to connector durability. At Richmon Ind., we recommend considering these key materials:

• Housing Materials: High-temperature thermoplastics (LCP, PPS)
• Contact Materials: Copper alloys with appropriate plating
• Plating Options: Gold, tin, or palladium for different requirements

Environmental Resistance Planning

Environmental factors significantly impact connector performance. According to IPC standards, connectors must withstand various environmental challenges:

• Temperature variations (-40°C to +85°C typical range)
• Humidity resistance (up to 85% RH)
• Chemical exposure protection

Mechanical Design Considerations
