Description

High Precision Alumina Advanced Metallized Ceramic Plate with Au Plating

Specification of metalized ceramic plates:

1. Forming methods: tape casting, slice casting, dry pressing, and ISO pressing

2. Available material: Alumina(Al2O3), Aluminum nitride (AlN) and Beryllia (BeO)

3. Size capability: min. size to be 1mm x 1mm, max. size to be 240mm x 280mm

4. Tolerance: thickness with +/-0.05mm. Length and width with +/-0.5mm or better

5. Surface finish: metalizing, polishing, lapping and so on

6. Secondary process: fine grinding, laser cutting and so on

The classical types of metallization:

1 Ceramic substrate + Silver (Ag) plating

2 Ceramic substrate + Molybedum (Mo-Mn) plating

3 Ceramic substrate + Copper (Cu) plating

Benefits of the metalized ceramic plates:

1. High bonding/brazing strength, It can be up to 150 MPa after brazing

2. High voltage, high current and high-temperature resistance

3. High thermal conductivity, up to 24 W/m.k at room temperature

4. With a low dielectric constant and small dielectric loss

5. High mechanical strength, flexural strength can be up to 338 MPa

6. Smooth surface free of bending, camber, and micro-cracks

7. Easy to be machined with precision dimensions and goods flatness for multiple layers

8. High reliability under high humidity and high-temperature working environment

9. Low coefficient of thermal expansion, less than 8 x 10 -6 from room temperature to 800℃

10. Excellent chemical stability, resistant to most strong acids and alkalis, free of rust forever

11. Free of any hazardous substances, meet RoHS and REACH regulation fully

12. Sufficient raw material supplying with competitive price

Description of ceramic metallised substrate:

Given the properties of good heat dissipation properties, minimum electric resistance, and vacuum tightness, metalized ceramics are ideal components for high vacuum, high voltage, and high-pressure applications.

By applying a thin metallic coating(general Mo/Mn, or W) as a base layer with high-temperature sintered, Furthermore, plated with Nickel/Silver/Copper/Gold to the surface of the ceramic, the bonding between ceramic parts and metal items can be achieved, which is also known as ceramic metallization.
Tungsten and Moly-Manganese metallizations have higher adhesion to the substrate than Thick-film metallization.
We supply a great of ceramic metalized plates in different technical materials, it mainly includes alumina, aluminum nitride, and beryllia ceramics. These ceramic substrates are shaped by tape casting, ISO pressing or Dry pressing with a very dense body.

A variety of different patterns, different configuration metallized ceramic plates are available to supply via laser cutting, fine grinding and so on. All these metallized ceramic plates offer to tighten tolerance.

Applications:
Widely used in thick film circuits large-scale integrated circuits, hybrid IC, semiconductor packages, chip resistors, networks resistor, focusing potentiometer, power modules, power hybrid circuits and other related fields of electronic industry.
