Ceramic Substrate Properties

2021-10-22

First, the nature of the ceramic substrate

1. Mechanical properties: (formation of circuit wiring)

a. Have a high high mechanical strength, in addition to carrying components, can also be used as support components;

b. Processability, high dimensional accuracy, easy to achieve multi-layered;

c. Smooth surface, no warpage, bending, microcracking, etc.

2, electrical performance:

a. Insulation resistance and insulation - resistant voltage height;

b. The dielectric constant is low, the dielectric loss is small.

c. Performance is stable under conditions of high temperature and high humidity, ensuring reliability;

3, thermal properties:

a high thermal conductivity;

b. The coefficient of thermal expansion is matched with the related material (especially the coefficient of thermal expansion of Si);

c. Excellent heat resistance.

4, other properties:

a. Good chemical stability, easy metallization, strong circuit graphics and strong attachment;

b. No moisture absorption, oil resistance, chemical drug, small A ray release;

c. The substance used is no pollution, non-toxic, the crystal structure is not changed in the temperature range; D. The raw material resources are rich, the technology is mature, the manufacturing is easy, and the price is low.
