What material is the PCB board made of

Regarding PCB, I believe many people have heard of it, but they don’t know what material PCB board is made of. There is more knowledge in it. Different PCB boards use different materials. Today I will briefly introduce you one time.

PCB board is also called printed circuit board or printed circuit board. Copper clad laminate composed of substrate, copper foil and adhesive is the main material of PCB board. The substrate is also called an insulating layer board, which is composed of polymer synthetic resin and reinforced materials; the copper foil is covered on the substrate, which has high conductivity and good solderability. Only one side of the substrate is covered with copper foil, which is called single Surface copper clad laminate, basically both sides are covered with copper foil, we call it double-sided copper clad laminate. Commonly used copper clad laminates have three thicknesses of 1.0mm, 1.5mm and 2.0mm; the role of the adhesive is to firmly cover the copper foil on the substrate.

What are the common copper clad laminates? The editor has sorted out the following:
FR-1 ──Phenolic cotton paper: commonly known as bakelite (more economical than FR-2)
FR-2 ──Phenolic cotton paper
FR-3 ──Tissue paper, epoxy resin
FR-4──Glass cloth, epoxy resin
FR-5 ──Glass cloth, epoxy resin
FR-6 ──Frosted glass, polyester
CEM-1 ──Tissue paper, epoxy resin (flame retardant)
CEM-2 ──Tissue paper, epoxy resin (non-flame retardant)
CEM-3 ──Glass cloth, epoxy resin
CEM-4 ──Glass cloth, epoxy resin
CEM-5 ──Glass cloth, polyester
AIN ──Aluminum Nitride
SIC ──Silicon Carbide
G-10 ──Glass cloth, epoxy resin

Through the above explanation, I believe you have a certain understanding of "what material is a PCB board made of".
