How to Use

To use the 3M™ Thermally Conductive Acrylic Interface Pad 5590H, cut the pad to the desired size and shape to fit between the heat-generating component and the heat sink or spreader. Peel off the protective liner and apply the pad to the component, ensuring good contact. The pad’s slight tackiness aids in placement, and its conformability allows it to fill gaps and irregularities, enhancing thermal transfer. Once in place, assemble the heat sink or spreader over the pad, applying appropriate pressure to ensure optimal contact.

Cautions

• Store the pads in their original packaging at 21°C (70°F) and 50% relative humidity to maintain product integrity.
• Avoid contamination of the pad surfaces to ensure optimal thermal performance.
• Ensure that the pad thickness selected is appropriate for the gap between components to avoid excessive compression or insufficient contact.
• Follow all safety guidelines and datasheet recommendations provided by 3M for handling and application
