Alumina Ceramic Substrate | Ceramic Substrate for Chip Resistors

Alumina ceramic substrates are widely used ceramic substrates. It is prepared by tape casting. Appropriate mineral raw materials are added to the 96% alumina ceramic substrate material as a co-solvent. The ceramic substrate has the main advantages of small size, light weight, high temperature resistance, high electrical insulation performance, low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability, and thermal expansion coefficient similar to the component, which greatly improves the circuit performance. The reliability and wiring density of the circuit are the carrier material of the chip resistor element.

Alumina Ceramic Substrate | Thick Film Hybrid Circuit Ceramic Board

Alumina Ceramic Substrate | Better thermal cycle performance, high cycle times and high reliability. Like the PCB board (or the IMS substrate), it can etch the structure of various patterns; no pollution and no pollution. The thermal expansion coefficient is close to that of silicon, which simplifies the production process of power modules. The tape-cast ceramic substrate has good flatness, smooth surface and good electrical properties; high thermal conductivity, thermal expansion coefficient matching other materials; good mechanical properties; high temperature, high pressure and high stability. It is used in ceramic copper clad laminates, ceramic circuit boards, ceramic heating plates, thick film circuit boards and other products.

Principle of Alumina Ceramic Substrate

Alumina Ceramic Substrate | There is an oxide film on the surface of the alumina ceramic liner, which will improve the hardness and wear resistance of the liner. Its oxide film formation principle is no different from that of water electrolysis. Not only molecular oxygen is precipitated on the plate anode, but also ionic oxygen and atomic oxygen, and molecular oxygen appears in the reaction. The aluminum of the anode of the lining plate is precipitated and oxidized to form anhydrous aluminum oxide film. However, the generated oxygen does not completely chemically interact with the aluminum, and part of it is precipitated in the form of gas and adheres to the surface of the lining plate to form an oxide film. The principle of alumina ceramic liner generates an oxide film, which has very good lubricity and insulation, and can absorb various lubricants.
