With the continuous advancement of technology, the quality control of the internal PCB circuit boards is becoming more and more stringent.

Information

With the continuous advancement of science and technology, the continuous improvement of people's living standards, the continuous development of smart phone technology and wearable electronic technology, intelligence, thinness, and miniaturization have become the mainstream, and consumers will have higher and higher product quality requirements. Therefore, as a laser marking machine manufacturer, the quality control of the internal PCB circuit board is becoming more and more stringent. It must be better to win consumers, win the recognition of customers, and achieve secondary purchases, such as Apple, Huawei, etc. Technology leader.

 

 

PCB is one of the important components of the electronics industry. The output value of the industry accounts for about a quarter of the total output value of electronic components. It accounts for the largest proportion in the various electronic component sub-industries, and the flexible PCB board (ie FPC) is the growth in the PCB industry. One of the fastest sub-industries. From the perspective of development trends in various regions of the world, after large-scale reorganization, migration and technology replacement, domestic PCB and FPC production and processing companies have seized the opportunity to transfer electronic products to the country, which has further increased the proportion of domestic circuit board output in the international market.

In order to better control the quality of products, it is necessary to record relevant production information to facilitate the full traceability and quality control of electronic products. The internal structure of the product-PCB marking information needs to be clear, and at the same time increase productivity and reduce costs in production. Reduce pollution and adapt to the development of multi-variety, small-batch production.

Identify string, one-dimensional code, two-dimensional code and other information on the PCB board, and upload it to the database through camera recognition, automatically reject unqualified products, and realize the product quality traceability of the entire internal process, from source supplier information to product delivery data Tracking, tracking the whole process, maximizing product quality, and effectively realizing the control of automatic production of products.

In order to better realize the management and control of many pcb boards in the product production process, marking information on pcb boards, such as production batches, characters, bar codes and other information, has become the development trend of the industry. Laser marking processing, as a high-tech means of marking processing, has advantages that traditional processing methods can’t match. Unlike traditional processing methods, laser processing uses high-energy-density lasers to locally irradiate the workpiece to vaporize or vaporize the surface material. A marking method in which a chemical reaction that changes color, leaving a permanent mark.


PCB laser marking machine is a special model specially used for marking bar codes, two-dimensional codes, characters, graphics and other information on printed circuit boards. It integrates high-performance UV/CO2/Fiber light source, high-pixel imported CCD camera, and micron-level mobile module to realize automatic positioning before coding and automatic reading and rating after coding.

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
