With the development of PCB technology in the direction of high density and refinement, the role of multilayer PCB board is becoming more and more important, and it is widely used in various fields. Below, is the explanation of several common problems of engineers about multi-layer PCB circuit boards:
1. How many layers does a multi-layer PCB board have?
PCB boards were originally based on single and double panels. Later, with the development of technology, multi-layer PCB boards were needed to realize the interaction of multi-layer circuits. Components range from simple single and double panels to 4, 6, 8, 10, 12 or even 22 or more layers. There is no conclusion on the question of how many layers a multilayer PCB board has at most. For R&D institutions, the number of layers of PCB depends on the product requirements and functions of the electronic PCB application.
2. Is the more layers of multi-layer PCB board the better?
Generally speaking, the more layers there are, the more difficult it is to manufacture and the higher the cost; the number of layers is determined by the requirements of the PCB application product. Of course, when the engineer is drawing the board, he must also consider various factors such as the feasibility of the process, the production cost, and the realization of functions to decide how many layers to make.
3. How to make a multi-layer PCB circuit board?
Its production process is similar to that of ordinary single- and double-sided panels, but there is one more lamination process for multi-layer circuit boards, and the requirements will be relatively high, often requiring multi-layer lamination. In the production process, the production cycle will be longer than that of ordinary double-sided panels, and the cost will be much more expensive.
