Clamping Force Performance Data and Thermal Testing

Performance Testing
Excessive shock and vibration is common in computing platforms deployed in harsh environments across a range of defense and industrial applications. Systems with limited or no airflow and containing high wattage board payloads are expected to operate with high reliability in extreme ambient temperatures every day. Effective clamping force is critical in applications demanding resistance to high shock and vibration and low thermal resistance ensures efficient heat transfer away from board components. Elma’s SureLock family of card edge retainers offer high and evenly distributed clamping forces over the length of the retainer. This provides solid mechanical rigidity while the consistent surface to surface contact ensures maximum heat transfer.
