Current PCBs are either single-sided (a layer of copper), or two-sided / double-sided (there is a substrate layer between the two copper layers), or multilayer (multiple of double-sided PCB). Common PCB thicknesses are: 0.70mm, 0.80mm, 0.95mm, 1.00mm, 1.27mm, 1.50mm, 1.60mm, 2.00mm, 2.40mm, 3.00mm, 3.20mm, 3.50mm, 4.00mm, 6.40mm.
Multilayer PCB Standard Size is related to the actual number of layersAiPCBA is a PCB and PCBA manufacturer that can provide one-stop PCB production services, aiming to create a PCB manufacturer with outstanding quality and cost-effectiveness.

Before introducing Multilayer PCB Standard Thickness, let me talk about 2 important PCB stacking concepts
Multilayer PCB the main material: Prepreg and Core
The difference between Prepreg and Core:
1. Prepreg is a material in PCB. The former is semi-solid, similar to cardboard, and the latter is hard, similar to copper;
2. Prepreg is similar to adhesive + insulator; Core is the basic material of PCB, the two are completely different functions;
3. Prepreg can curl but the Core cannot bend;
4. Prepreg is not conductive, and the core has copper layers on both sides, which is the conductive medium of the printed board.
The following table represents a standard multi-layer PCB stack. The final thickness of all typical PCBs listed below is 0.62 inches ± 10%, the copper weight is 1 ounce, and the unit of measurement is in inches.
Unit conversion reference: 0.62 inches = 15.748 mm
