Organic basic materials consist of a base and some binding compound.
They have a low dielectric constant, an insignificant angle tangent of the dielectric loss. Their price is available. They are used in household, industrial (specialized) equipment.
Basic inorganic materials have significant factors of heat conduction, resistance to temperature fluctuations.
At the same time the coefficient factors of the thermal expansion are close to zero or negative. They are used as components capable of operating under harsh operating conditions.
Types of organic materials base:
It is used in combination with fluoroplastics or epoxy compounds. It is a base for CEM-III.
It is a widespread basic material. It is simple in operation and has different thicknesses of weaving. It is used in FR-4.
It is applied in Rogers HDI boards. It is often combined with aramid paper and epoxy resins. The material can be etched, and laser drilled well, it is possible to make transition vias by chemical methods.
— Ceramic.
— Silicon, as well as compounds based on silicon oxide.
— Enameled/oxidized metals. The most popular are aluminum.
— Phenolic/epoxy resins.
— Polyimide.
