From two common sense to understand how to make multilayer PCB

The inner layer’s mater almost some with outer layer

We have introduced many articles introduce how to make a multilayer PCB.
Many people confuse its construction, especially inner layer PCB material.
First of all, you should know the inner layer PCB material.
To produce the inner layers of our multilayer PCB, we start with a panel of laminate.
Usually inner layer PCB material has been same with outer layers.
The difference is outer layer PCB material copper will be electroplating at the beginning.

The stack up of multilayer PCB material

The construct of multilayer PCB board were very complex.
But here David doesn’t want to introduce more about it due to we have discussed so many times before.
There was a very similar definition.
Because understand stack up of PCB multilayer PCB material, can help your understand multilayer PCB construction more clearly.
Laminate is an epoxy resin and glass-fibre core with copper foil pre-bonded onto each side.
