Product Description

Custom High Purity Pink Aluminum Oxide Al2O3 Substrate Alumina Ceramic Wafer

Product Description

Pink alumina ceramic substrates are typically pink in color due to the addition of Cr2O3. Their basic properties are similar to those of ordinary alumina ceramic substrates, such as high mechanical strength, excellent insulation, high temperature resistance, and chemical stability.

 

The effects of pink may include:

1. Dielectric property optimization: Some studies have shown that moderate chromium doping can reduce dielectric loss at high frequencies.

2. Enhanced mechanical properties: Cr2O3 refines grain size and improves flexural strength.

3. Laser processing adaptability: The pink surface has a higher absorption rate for specific wavelengths of laser light, making it suitable for precision drilling or cutting.

4. Appearance recognition: Colors can be used to distinguish between different specifications or functions of substrates.

Product Applications

Pink alumina ceramic substrates occupy a unique position in high-end electronics and industrial fields thanks to their balanced performance and special modifications.

Electronics Industry

1. High-power LED packaging: Utilizing its high thermal conductivity and insulation properties, it is used as a COB (Chip-on-Board) substrate, especially for UV or IR LEDs that require high temperature resistance.

2. RF/microwave devices: Used in filters, resonators, etc., its low dielectric loss is suitable for high-frequency circuits.

Sensors and Precision Instruments

1. Pressure sensors: Used in automotive and aviation applications to withstand high-temperature, high-pressure environments (e.g., turbine pressure monitoring).

2. Biosensors: Chemically inert, they can be used for corrosive medium detection.

Special industrial applications

1. Laser heat sinks: Absorb specific laser wavelengths, assist heat dissipation, and reduce thermal lensing effects.

2. Marking and differentiation: Pink is used for quick identification of multi-level circuits or modules.
