This article takes you to know HDI board proofing

Information

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.

The evaluation system of the circuit board factory should follow the following principles

The evaluation system of the circuit board factory should follow the following principles

Establishing a good cooperative relationship with circuit board factories is conducive to cost reduction, response time reduction and the creation of new market value, etc. The core issue is how to choose the ideal circuit board factory. There are many factors involved in the evaluation of circuit board factories, and the evaluation index systems are diverse, both qualitative and quantitative, and the index weights are also different. Therefore, it is necessary to establish a universal and expandable evaluation index system for circuit board factories. , And the indicator system should follow the following principles:
The use of soft and hard circuit boards?

The use of soft and hard circuit boards?

In our daily life, circuit boards are mostly single-sided, double-sided, or multi-layer boards, rigid boards, metal-based circuit boards, aluminum, copper substrates, thermally conductive fiberboards, etc., do you know what a flexible and rigid circuit board is? Rigid-flex circuit board: refers to a special circuit board made by pressing a rigid circuit board (PCB) and a flexible circuit board (FPC). The main board materials used are rigid board FR4 and flexible board polyimide (PI). Rigid and flexible circuit boards combine the rigid characteristics of rigid circuit boards and the advantages of flexible circuit
Soft and hard circuit board production process

Soft and hard circuit board production process

The flexible and hard circuit board is the flexible circuit board and the rigid circuit board. After pressing and other processes, they are combined according to the relevant process requirements to form a circuit board with FPC characteristics and PCB characteristics. In the past, two hard boards were connected by using soft boards and connectors to connect each other. In order to improve the reliability of the connection between the rigid board and the flexible board, the flexible board is directly fabricated between two rigid boards in the printed circuit board (PCB) factory, which can avoid the subsequent connection process, whether it is a rigid board manufacturer or FPC manufacturers are now able to supply rigid-flex boards. Under the demand for light and thin end products, the
