This article takes you to know HDI board proofing
In today's safe and convenient living conditions, many new products have been produced accordingly. Today we will mainly talk about HDI board and HDI board proofing process.
HDI is an abbreviation for high-density interconnection, and it is also a technology for printed circuit boards. It is mainly based on a circuit of micro-blind and buried vias to distribute high-density circuit boards. HDI is specially designed for small-capacity users, because it is based on compact products, and adopts modular and parallel design. In most cases, it uses various patented technologies and digital signal processing technologies, and has strong shortcomings. Time overload capacity and adaptable load capacity on a global scale.
The application of HDI boards has gradually expanded in recent years. It is generally manufactured by the layer-by-layer method. The more the number of layers, the more advanced the technology of the panel, and the higher the grade. Ordinary HDI boards are basically single-shot, while high-end HDI boards use two or more technologies. At the same time, technicians will also use other advanced technologies such as stacked holes and laser direct drilling. High-end HDI boards are mainly used in electronic devices such as mobile phones and advanced digital cameras.
It has many advantages. For example, in improving product performance, HDI board can present relatively low electrical noise of family planning. Not only that, it can also minimize the structure of connection holes and circuit branches, and have a stable voltage path, which is comparable to other products. It is closer to the distribution of capacitance, and even in a specific environment, it can play a role in blocking radiation.
However, HDI boards still face new challenges, namely, proofing technology. Due to the lack of professional talents for its application technology, and the related knowledge of this industry is not perfect enough, it is impossible to estimate the stacking status, price, number of holes and other issues at the beginning of the project design, and at the same time, the later There are also certain challenges in assembly. How to select a structure reasonably is a key factor related to the performance and cost of the HDI board.
In the HDI board proofing process, the selection of materials must also be fully considered. In most cases, the raw materials for HDI board proofing are generally resins, and some will also use improved acrylic resins, which are mainly determined by its main application place and environment.
Today's article is over here. I hope you have a deeper understanding of HDI board proofing after reading this article.
