0.4mm PCB board thickness is the beginning of multilayer PCB

Feb 17 2020

The 0.4mm PCB board thickness is the beginning of a multilayer PCB, which is almost the minimum thickness for a PCB engineer to design a multilayer board.

By combining different core thicknesses and prepregs, a wide range of finished PCB thicknesses can be achieved. However, customers can choose from a variety of laminate thicknesses ranging from 0.008 inch to 0.240 inch, including 0.2 mm (0.0079 inch), 0.4 mm (0.016 inch), 0.5 mm (0.020 inch), 0.6 mm (0.024 inch), 0.8 Mm (0.032 inch), 1.0 mm (0.04 inch), 1.2 mm (0.047 inch), 1.5 mm (0.062 inch), 1.6 mm (0.063 inch), 2.0 mm (0.079 inch), 2.3 mm (0.091 inch), etc.

The board thickness is the measured mm thickness of the substrate, including the copper foil on the top and bottom. So the thickness of the circuit board does not represent the final thickness of the PCB, because we need to add plating, solder mask, etc. If you need a final thickness of 0.4mm, then we will use 0.3mm raw materials to manufacture your PCB board

PCB thickness range:

0.2mm PCB 0.4mm PCB 0.6mm PCB 0.8mm PCB

1.0mm PCB 1.2mm PCB 1.5mm PCB 1.6 mm PCB

2.0mm PCB 2.4mm PCB 3.0mm PCB 3.2mm PCB

3.6mm PCB 4.8mm PCB 5.6mm PCB
