The components of multilayer PCB: thin laminates

A multilayer board consists of copper foils, thin rigid laminates and prepreg sheets.


Thin laminates are used for inner cores and are available in so many different thicknesses that almost any specified build-up can be accomplished.


Different thickness of thin laminates

mmmils mmmils
0.05020.36014
0.07530.41016
0.10040.46018
0.12550.51020
0.15060.56022
0.17570.61024
0.20080.66026
0.250100.71028
0.300120.76030

The thicknesses are valid for the bare laminate, with the copper foil being excluded. We can see the cores are quite thin. For a total thickness of 1.6mm (0.063inch) board, the more layers, the thinner the laminates should be. See our reference Multilayer PCB stackup for 0.063inch thick.



FAQ


Do you sell cheap FR-1, CEM-1 PCB?
Yes, we just offer single sided PCB made of FR-1 and CEM-1. We also use punching tool for the contour for the mass production.
