Description
The ceramic substrate is based on electronic ceramics and forms a
sheet-like material supporting the base for membrane circuit
components and integrated Circuit components.
Features of ceramic substrate:
Ceramic substrate has the main advantages of high temperature
resistance, high electrical insulation, low dielectric constant and
dielectric loss, large thermal conductivity, good chemical
stability, and thermal expansion coefficient similar to that of the
component. However, the ceramic substrate is relatively brittle,
the substrate size is small and the cost is high.
Classification of ceramic substrates
Classification by the application field of ceramic substrates: HIC
(hybrid integrated circuit) ceramic substrates, ceramic substrates
for focusing potentiometers, ceramic substrates for laser heating
and fixing, chip resistor substrates, network resistor substrates,
etc.;
Classification by processing method: molded substrates and laser
scribing substrates.
