ceramic insualtor washers for electronic packing of diodes, triodes, MOS tubes and small-scale ICs (TO220, TO3P, TO264, TO247)

Ceramic wafers made of alumina ceramic have excellent properties of low weight, good electrical insulation, low dielectric loss, good thermal conductivity and high heat resistance etc, it is an ideal material for electrical insulation and heat dissipation purpose in electronic industries. Alumina ceramic wafers have been developped for electronic package of high-power diodes, triodes, MOS tubes and small-scale ICs (TO220, TO3P, TO264, TO247). The thickness of alumina ceramic wafers could be 0.25mm, 0.385mm, 0.5mm, 0.635mm, 0.8mm, 1.0mm, 2mm, 3mm , 4mm or customized size.  The flatness and surface roughness are good, the product size and material properties are stable. Mascera will adopt corresponding production technologies according to customers' different requirement for dimensions or quality. We are capable to provide alumina ceramic wafers in short time for big quantities to meet customers' using demands.

Advantages of Alumina Ceramic Wafers

1. The ceramic wafer itself does not store heat, directly dissipates heat, and is fast, reducing the influence of the insulating layer on the thermal efficiency;

2. Ceramic polycrystalline structure enhances heat dissipation. Under the same conditions, surpass most of the thermal insulation materials on the market;

3. The feature of multi-directional heat dissipation to speed up heat dissipation;

4. Electrical insulation, high thermal conductivity, high voltage resistance, high temperature resistance, abrasion resistance, high strength, oxidation resistance, acid and alkali resistance, and long service life;

5. Effective anti-interference (EMI) and anti-static;

6. Natural organic materials meet environmental protection requirements;

7. Small size, light weight, high strength and space saving;

8. Alumina ceramic wafer is suitable for IC, MOS, triode, IGBT and other surface heat sources that require heat dissipation;

9. It is especially suitable for high-power equipment, and the design space is light, thin, short and small.
