Alumina ceramic substrates from Laimeisi Silicone Industry are designed for high-precision applications, particularly in electronics and power cooling systems. The material is composed of at least 95% alumina, providing excellent thermal conductivity and electrical insulation. These substrates are customizable in size and shape, with square forms being the most common for industrial use.
The density of these substrates is specified at 3.6 g/cm³, a standard value for alumina ceramics that ensures a balance of strength and thermal performance. Thermal conductivity is rated at 20 W/m·K, making them effective for heat dissipation in electronic components. The substrates are also insulated and heat-resistant, which is critical for applications such as TO-220 packages and power modules.
These substrates are widely used in the Chinese technical ceramics industry, particularly for dispersing heat in high-power electronic devices. Buyers often source them for custom projects, with delivery typically arranged within 3 to 7 days after payment. Packaging is tailored to customer requests, ensuring safe transit for these delicate components.

Sourcing Alumina ceramic substrate from Laimeisi Silicone Industry - China Import Guide
Before ordering, confirm the exact alumina content and thermal conductivity values, as these are critical for heat dissipation in electronic applications. Request material test reports to verify the substrate’s dielectric strength and flexural strength, especially for high-stress or high-voltage uses.
Clarify the supplier’s lead times, which are typically 3 to 7 days after payment, and discuss Incoterms such as FOB or EXW to align with your logistics requirements. Ensure packaging is customized to your needs, as alumina substrates are fragile and require protection from impact and moisture during transit.
Arrange for quality checks, including dimensional verification and surface finish inspections, to be conducted before shipment. Request documentation such as certificates of conformity and inspection reports to validate the material’s compliance with your specifications. For critical applications, consider third-party inspection to ensure consistency.
