Product Detail:

Multilayer PCB refers to a printed circuit board with more than two copper layers, such as 4L, 6L, 8L, 10L, 12L, etc. As technology advances, people can place more and more copper layers on the same board. Currently, we can produce 20L-32L FR4 PCB.

Through this structure, engineers can place traces on different layers according to different purposes, such as power layer, signal transmission layer, EMI shielding layer, component assembly layer, etc. In order to avoid too many layers, a Buried Via or Blind Via is designed in a multilayer PCB. For boards with more than 8 layers, high TG FR4 materials will be more popular than ordinary TG FR4.

The more layers, the more complicated and difficult it is to manufacture, and the more expensive it is. The delivery time of multi-layer PCB is different from ordinary PCB, please contact us for the exact delivery time.

The general structure of the multilayer board is as follows:

Top silkscreen: Identify the name, board number, data, etc. of each PAD;

Finishing of the top surface: protect the bare copper from being oxidized;

Top Soldermask: Protect copper from being oxidized and not being soldered during SMT;

Top Trace: Copper is etched to perform different functions according to the design

Substrate/core material: non-conductive, such as FR4, FR5

Prepreg (PP)

Intermediate layers, such as GND, VCC, Inner 3, Inner 4, etc.
