The appearance of electronic products is one of the important factors to control the quality. With the rapid development of information technology, the demand for electronic components in China is gradually increasing. At present, electronic components are also gradually developing towards thin, intelligent, integrated and miniaturized. Whether there are defects or not not not not only affects the beauty of the product, but also directly affects the use and subsequent processing of the product itself, bringing significant economic losses to the enterprise.

IC chip appearance detection is a detection equipment based on machine vision system. It can replace the traditional manual detection, realize the online high-speed automatic detection of product appearance and the automatic identification of product surface defects. Electronic components are the upstream products of the electronic information industry chain and the basis for the development of communication, computer and network, digital audio and video and other systems and terminal products. Whether electronic components work reliably determines the normal operation of electronic equipment. Because such products are generally small and have high requirements for quality, it is difficult to detect in large quantities manually. It is necessary to use machine vision appearance detection equipment to detect appearance defects.

What defects can machine vision appearance inspection equipment be used for electronic components?

Appearance inspection is an indispensable part of the product inspection process. In recent years, machine vision appearance inspection equipment has gradually replaced the traditional manual inspection and become a magic weapon for major manufacturing enterprises to improve production efficiency and delivery quality. Electronic components industry is an important part of the development of electronic information industry, and the quality requirements are very strict. So, what defects can machine vision appearance inspection equipment be applied to electronic components?

Machine vision appearance inspection equipment is an equipment that uses machine vision technology to replace human eyes and detect product appearance defects efficiently and quickly. It is composed of industrial camera, light source, sensor and machine vision detection system software. It converts the captured target into image signal, transmits it to special image processing system, and converts it into digital signal according to pixel distribution, brightness, color and other information; The image system performs various operations on these signals to control the operation of field equipment according to the judgment results.

Electronic components are the upstream products of the electronic information industry chain and the basis for the development of communication, computer, network, digital audio and video systems and terminal products. The reliable operation of electronic components determines the normal operation of electronic equipment. As such products are generally small and have high quality requirements, it is difficult to pass large-scale manual inspection, so machine vision appearance inspection equipment is needed to detect appearance defects.

Machine vision appearance inspection equipment can not only detect the appearance defects of electronic components, but also be applied to precision parts, clothing accessories, mobile phone parts and other fields, so as to improve the production automation level of major manufacturing enterprises and market efficiency. With the rapid development of microelectronics technology, the integration of various semiconductor chips is becoming higher and higher. At the same time, the volume of the chip tends to be miniaturized and miniaturized, which puts forward higher requirements for the detection of the chip.
