Multilayer pcb board production, multilayer pcb board design teaching skills what are the research methods

With the development of electronic technology, the application of multilayer PCB boards is becoming more and more widespread. Unlike single or double layer PCB boards, multilayer PCB boards can achieve a higher degree of integration while ensuring circuit functionality. So in the production process of multilayer pcb fabrication printed circuit boards, what are the key technologies that require special attention?

First, choose the right material

It is very important to choose the right pcb material, mainly including substrate materials and copper cladding thickness. FR-4 is usually used as the substrate material, which has excellent insulation properties and mechanical strength. In addition, the thickness of copper is also a factor to consider. Usually choose 1oz (35um) and 2oz (70um) copper cladding layer for different board requirements.

Second, a good layout and alignment

In the multilayer pcb production, layout and alignment is a crucial part. Good layout we can effectively reduce environmental interference and cross-coupling, and enterprises can make the board more beautiful. Alignment needs to be effectively avoided when the students are too dense development and social appearances of some unnecessary coiled winding, to maintain the simplicity of the board can continue to improve the stability of the circuit board.

Third, rational planning of power supply and grounding

Power supply and grounding design is the key to ensure stable circuit performance. In the PCB factory, you need to plan the location of the power supply and grounding, so that it is as short and straight as possible, to reduce the impact of the load current on the grounding, thus ensuring stable circuit performance.

Fourth, a good pad design

Good pad design for circuit stability and electrical connectivity is critical. In the production of multilayer boards, pad design needs to be carefully planned, try to avoid blind holes and blind holes in the wrong design to ensure positive positioning of the pad.

In the production and design of multilayer pcb, you need to pay attention to the above key skills in order to produce a multilayer PCB with stable performance, beautiful layout and easy to use.For beginners, the production and design of multilayer pcb can improve the level of electronic technology and hands-on ability, and it is a worthwhile technology to try.
