PCB knowledge: 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

mm	mils	mm	mils
0.050	2	0.360	14
0.075	3	0.410	16
0.100	4	0.460	18
0.125	5	0.510	20
0.150	6	0.560	22
0.175	7	0.610	24
0.200	8	0.660	26
0.250	10	0.710	28
0.300	12	0.760	30

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
How do you pack the PCBs?
PCBs are packed with Polyethylene air cushion film(vacuum plastic bags) per 20-25 pieces. Pearl cotton (Polyethylene foamed sheet) are put inside carton box.
The hardness of carton box is KK grade(the highest hardness). Maximum gross weight for one carton is less than 12 kgs.
