A phase change thermal pad is a high-performance thermal interface material designed to improve heat transfer between heat-generating electronic components and heat sinks. The XTP-001 phase change thermal pad stays solid at room temperature, making it easy to handle, position, and install. When the operating temperature reaches around 50°C, the material softens and flows into small surface gaps, helping reduce interface thermal resistance.
XTP-001 is suitable for CPUs, memory modules, IGBT devices, DC/DC power converters, DC/AC inverters, custom power modules, and other semiconductor components that require reliable thermal management. With a thermal conductivity of 22.5±0.1 W/m-K, a thickness of 0.25mm, and low thermal impedance, it helps create a stable thermal path from the component to the cooling structure.
Before installation, make sure the surface of the chip, power module, or heat sink is completely clean. Dust, oil, moisture, or old thermal material may reduce contact quality and affect thermal performance. Use a clean lint-free cloth to wipe the surface and allow it to dry before applying the pad.
Choose the correct pad size based on the heat source area. XTP-001 is available in standard sizes such as 25×25mm, 20×30mm, 38×38mm, and 30×50mm, with custom sizes also available. The pad should cover the main heat-generating area without interfering with nearby components or mounting parts.
Carefully peel off the protective film before application. Avoid touching the thermal pad surface directly with your fingers, as oil or dust may affect performance. Hold the pad by the edge and keep it flat during handling.
Place the phase change thermal pad evenly on the heat source. Press it gently to ensure full contact and reduce trapped air. The pad should be flat, aligned, and free from wrinkles or bubbles.
After the pad is positioned, mount the heat sink or cooling plate on top. Proper mounting pressure helps the pad contact both surfaces evenly. During operation, once the temperature reaches the phase change point, the material softens and fills microscopic gaps between the component and the heat sink, improving heat transfer efficiency.
For best results, use the phase change thermal pad in applications where the interface gap is small and controlled. If the gap is too large, confirm that the pad thickness and compression conditions are suitable before assembly.
XTP-001 should be stored in a dry and cool environment, ideally between 8°C and 28°C. Avoid rain, direct sunlight, and high-temperature storage conditions. When stored properly at 25°C, the product has a shelf life of up to 24 months.
By following the correct cleaning, peeling, positioning, and mounting steps, XTP-001 can help electronic devices achieve lower thermal resistance, better heat transfer, and more reliable long-term cooling performance.
