Board-to-board connector stacking heights in wearable tech present unique engineering challenges that demand precision solutions. As wearable devices become increasingly compact while requiring enhanced functionality, manufacturers face critical decisions regarding optimal stacking heights that balance performance, reliability, and miniaturization requirements.
Understanding the Core Problem: Space Constraints in Wearable Devices
Modern wearable technology demands ultra-compact designs where every millimeter matters. Traditional connector solutions often fail to meet the stringent space requirements while maintaining reliable electrical connections. The primary challenge lies in achieving optimal board-to-board connector stacking heights that accommodate multiple PCB layers without compromising device wearability or functionality.
Key Technical Challenges
- Miniaturization Requirements: Wearable devices require stacking heights as low as 0.4mm while maintaining robust electrical connections
- Signal Integrity: Maintaining high-speed signal transmission across minimal vertical distances
- Mechanical Reliability: Ensuring connector durability despite repeated flexing and environmental stress
- Thermal Management: Managing heat dissipation in confined spaces with limited airflow
