Interpretation of several common problems about multilayer pcb circuit boards

With the development of pcba manufacturing technology in the direction of high density and refinement, the role of multi-layer pcb boards is becoming more and more important and widely used in various fields. Below, is the engineer's interpretation of several common questions about multi-layer pcb circuit boards:

1. How many layers does a multi-layer pcb board have at most?
The PCB board was based on single and double panels at first, and later with the development of technology, a multi-layer pcb board was needed to realize the interaction of multi-layer circuits. Components range from simple single and double panels to 4 layers, 6 layers, 8 layers, ten layers, twelve layers and even 22 or more layers. There is no conclusion for the problem of a multi-layer PCB board having a few layers at most. For RD institutions, the number of layers of PCB depends on the product requirements and functions implemented by the electronic PCB application.

2. Is the number of layers of multi-layer pcb board the better?
Generally speaking, the more layers, the more difficult it is to make, and the higher the cost; the number of layers is determined by the needs of the PCB application product. Of course, when the engineer draws the board, he must also consider the feasibility of the process, production cost, function realization and other factors to decide how many layers to build.

3. How to make multilayer pcb circuit board?
The production process is similar to that of ordinary single and double panels, but the multi-layer circuit board has one more pressing process, and the requirements will be relatively high, often requiring multiple lamination. In the production process, the production cycle is longer than that of ordinary double-panel production, and the cost is much more expensive.
