At present, in the field of electronic product processing, multi-layer circuit boards are indispensable as one of the important electronic components. At present, there are many types of PCB circuit boards, such as high-frequency circuit board plates, microwave circuit boards and other types of printed circuit boards that have gained a certain reputation in the market. Multi-layer circuit board factories have specific processing techniques for various board types. But in general, multilayer circuit board manufacturers need to consider three major aspects.
1. Consider the Choice of Process Flow
The production of multi-layer circuit boards is prone to be affected by many factors, and the number of layers, punching process, surface coating treatment and other technological processes will affect the quality of the finished PCB circuit board. Therefore, for these process environments, multi-layer circuit board production is fully considered in combination with the characteristics of the production equipment, and can be flexibly adjusted according to the types of PCB boards and processing requirements.
2. The Choice of Substrate
The base material of the circuit board can be divided into two types: organic material and inorganic material. Each material has its unique advantages. Therefore, the determination of the type of substrate considers various properties such as dielectric properties, copper foil type, base groove thickness, and processability characteristics. Among them, the thickness of the surface copper foil is a key factor affecting the performance of this printed circuit board. Generally speaking, the thinner the thickness, the more convenient the etching and the improvement of the precision of the graphics.
3. Consider the Setting of the Production Environment
The environment of the multi-layer circuit board manufacturing workshop is also a very important aspect, and the regulation of ambient temperature and ambient humidity are both crucial factors. If the ambient temperature changes too significantly, it may cause the holes on the base plate to break. If the environmental humidity is too high, nuclear energy will have an adverse effect on the performance of the substrate with strong water absorption, specifically in terms of dielectric properties. Therefore, it is very necessary for circuit board manufacturers to maintain proper environmental conditions during production.
PHILIFAST has their own PCB factory, and we can make PCBs from 1-32Layers.
