PCB substrate material

PCB substrate material

For example, the current FR-4 water green fiberglass board and black fiberglass board all have functions such as high temperature resistance, insulation, and flame retardancy. Everyone can choose materials according to their own needs.

There are two main types of printed circuit board substrates: organic substrate materials and inorganic substrate materials, with organic substrate materials being the most commonly used. The PCB substrate used varies depending on the number of layers. For example, 3-4 layer boards require prefabricated composite materials, while double-sided boards mostly use glass epoxy resin materials
