Learn PCB and Buy PCB---- PCB Classification --- Multilayer PCB
In order to increase the area that can be wired, multilayer board uses more single or double sided
wiring board.
PCB using a double side board as inner layer and two pieces of single layer as the outer layer or
two double-sided printed circuit board as the inner layer and two pieces of single layer as the outer
layer, through the insulation and bonding materials to press each layer together, and the conductive
pattern are as per design requirements for interconnection becomes the 4 layers of printed circuit
board, 6 layers of printed circuit board, also known as multilayer printed circuit board.
The number of layers of the board does not represent a separate layer of wiring. In particular, the
air layer will be joined to control the thickness of the board. Usually the number of layers is even,
and contains the outermost 2 layers. Most of the host mainboard is 4 to 8 layers of structure, but
the theory can be technically nearly 100 layers of PCB boards. Large supercomputers use quite
a lot of layers of mainframe board, but because this kind of computer can be replaced with a lot
of ordinary computer clusters, super multilayer board has gradually not been used. Because all
of the layers in the PCB are closely combined, it is generally not easy to see the actual number,
but if you look carefully at the motherboard, you can also see it.
PCB can be also classified by its softness. There're rigid PCB, flexible PCB and Rigid-flex PCB.
Metal core PCB and high frequency PCB are classified by its material.
