0.4mm PCB Thickness is a start for multilayer PCB , Almost is minimum thickness for PCB engineer to design a Multi-Layer boards.
An extensive range of finished PCB thicknesses can be accomplished with the combination of different core thicknesses and sheets of prepreg. However, the variety of laminate thickness options offered to our customers are range from 0.008 inches to 0.240 inches and they include 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 thickness given in mm of the base material measured including copper foil on top and bottom. So the board thickness does not represent the final thickness of the PCB as for that we need to add plating, solder mask, etc,if you need 0.4mm final thickness , then we will use 0.3mm raw material to manufacture your PCB board .
Rayming 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
We accept custom PCB thickness , If you have special requirement on PCB thickness, Welcome to send your design to firstname.lastname@example.org .
