Ceramic PCB Printed Circuit Board Manufacturing Company

Ceramic circuit boards are actually made of electronic ceramics and can be made of various shapes. Among them, the characteristics of high temperature resistance and high electrical insulation performance of ceramic PCB are the most prominent, and the advantages of low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability, and similar thermal expansion coefficient to components are also very significant. The production of ceramic circuit boards will use LAM technology, that is, laser rapid activation metallization technology. 

Used in LED field, high-power power semiconductor modules, semiconductor refrigerators, electronic heaters, power control circuits, power hybrid circuits, intelligent power components, high-frequency switching power supplies, solid-state relays, automotive electronics, communications, aerospace and military electronics components.

Different from traditional FR4 PCB board (wave fiber), ceramic materials have good high-frequency performance and electrical properties, and have properties that organic substrates do not have, such as high thermal conductivity, excellent chemical stability and thermal stability. Ideal packaging material for a generation of large-scale integrated circuits and power electronic modules.

Main advantages:

1. Higher thermal conductivity

2. More matched thermal expansion coefficient

3. Stronger and lower resistance metal film alumina ceramic circuit board

4. The solderability of the substrate is good and the operating temperature is high

5. Good insulation

6. Small loss at high frequency

7. High-density assembly is possible

8. Does not contain organic components, is resistant to cosmic rays, has high reliability in aerospace, and has a long service life

9. The copper layer does not contain an oxide layer and can be used for a long time in a reducing atmosphere
