The introduction of AVI

Printed circuit boards are an important component of modern electronic equipment. The quality of printed circuit boards has a crucial impact on the performance stability and lifespan of electronic products. To ensure the quality of printed circuit boards, AVI inspection technology has emerged.

 

1. Principle

AVI is an automatic visual inspection technology that uses advanced equipment such as high-resolution CCD cameras, light sources, and computer technology to quickly and accurately inspect printed circuit boards. The AVI inspector can automatically identify and display all components, wiring, and welding points on the printed circuit board. By analyzing and comparing the images of the pcb, defects such as short circuit, open circuit, reversed insertion, incomplete, offset, solder leakage, and poor punching of pins on the printed circuit board can be detected in a timely manner. At the same time, functions such as light leakage detection, virtual soldering detection, defect detection, and component discrimination have also been implemented.

 

2. Accuracy

AVI inspection technology is a high-precision and high-efficiency automatic detection technology. Compared to manual inspection, AVI inspection technology can greatly improve the detection accuracy and product manufacturing efficiency of printed circuit boards, while also greatly reducing defect rates and loss costs. The detection accuracy of AVI inspection technology has reached over 99.9%, which can effectively ensure the quality of the product.

 

3.Advantage

AVI examination technology has many advantages, mainly manifested in the following aspects:

 

(1) Efficiency: AVI inspection technology can quickly and efficiently perform automatic detection of printed circuit boards, greatly improving work efficiency and improving the production efficiency of enterprises.

 

(2) High accuracy: AVI inspection technology has high accuracy and can effectively detect various defects on printed circuit boards, greatly reducing product quality issues.

 

(3) Reliability: AVI inspection technology uses high-precision equipment to conduct long-term and reliable testing of electronic products, ensuring product quality.

 

4.Disadvantage

Although AVI inspection technology has high detection accuracy and work efficiency, there are still some shortcomings in current technology.

 

(1) High technical complexity: The application of AVI inspection technology requires specialized technical personnel to operate and maintain equipment, resulting in high costs.

 

(2) Unable to detect specific defects: AVI inspection technology still has certain blind spots for some relatively small or difficult to detect defects.

 

AVI inspection technology is an efficient and high-precision printed circuit board inspection technology. Although the technical complexity may be high, its superior detection accuracy and work efficiency can help enterprises improve product quality and save costs. With the advancement of technology and the popularization of applications in the future, it is believed that AVI inspection technology will become more accurate and cost-effective, adding new impetus to the development of the manufacturing industry.
