Common Materials in IC Circuit Substrates

'-FR-4, ceramic, and organic laminates are widely used core materials. FR-4 is favored for its excellent mechanical and thermal properties, while ceramic substrates are used in high-frequency and high-power applications due to their excellent thermal conductivity and electrical insulation.

-Copper is the primary conductive material used in IC substrates due to its high electrical conductivity and thermal properties. Gold and silver are also used in specific applications requiring high reliability and corrosion resistance.

-Advanced dielectric materials such as epoxy and polyimide are used to insulate the conductive layers. These materials offer excellent electrical insulation, thermal stability, and chemical resistance.

-ENIG, OSP, and immersion tin are common surface finishes that improve solderability and protect the substrate from oxidation and corrosion.

-Epoxy-based soldermasks are often used to protect circuitry and prevent solder bridges during assembly.
