Product Features
Insulation properties	Good insulation linearity and high reliability. The voltage resistance performance can reach 1000V and can be applied to high-voltage and high-power devices.
Heat dissipation	Low thermal expansion coefficient and high thermal conductivity. The thermal conductivity of AIN ceramic substrate can reach 170-240W/(m · K), and its excellent thermal conductivity greatly improves the heat dissipation of high-power packaged chips compared to organic packaging.
Air tightness	Good airtightness and stable chemical properties. The leakage rate is generally below 10%, which can protect the stable operation of the chip extender.
frequency characteristic	Low dielectric constant and good high-frequency performance. Suitable for optical communication ceramic tube shells, ceramic tube shells for special use, etc.
Corrosion resistance	Superior corrosion resistance ensures that the chip is not affected by the environment when working in high acidity, alkalinity, high salinity, and humidity conditions.

Product packaging specifications	PRODUCT PACKAGING
	SPECIFICATION
Product packaging and usage specifications
1. The acceptance inspection of the product should be carried out in the purification room. 2. When using the product, work caps, masks, and finger cots should be worn, and plastic tin clips should be used to pick up the product. It is strictly prohibited for the skin to come into direct contact with the product to prevent contamination. 3. When unpacking, use scissors to cut open the packaging bag along the inner side of the heat sealing line, and then slowly extract the product to prevent it from being misplaced and scratched. 4. The opened shell should be stored in a clean moisture-proof cabinet, with a temperature controlled at 25 ºC ± 1 ºC and a relative humidity of ≤ 45%; If not used for a long time, it should be stored in vacuum packaging. The storage device is usually stored for one year, and the temperature in the storage room is controlled at 23 ºC+3 ºC, with a relative humidity of ≤ 70%. 5. Returned products should follow the product packaging process to avoid misalignment and scratches during transportation. 6. The packaging material does not contain oxygen elements.
Product packaging process
1. Load the product into a clean packaging tray. 2. The product tray is packed in a packaging bag and vacuumed. It is recommended to maintain a vacuum degree of 0.03MPa~0.07 MPa, evacuate for 15~25 seconds, seal at a temperature of 150 ± 10 ºC, and seal for 3~4 seconds. 3.
