  • PCB Board Material, PCB Material Type

    Layers tend to have the number 1, or any of the next four even numbers: 2, 4, 6, 8. Layer boards sometimes have odd numbers, but these are rare and would make hardly any difference. For example, the PCB base material in a 5 layer or 6 layer board would be virtually identical. The two layer types have different functions.
