Portable EL visual inspection instrument is an advanced non-destructive testing equipment, which is widely used in the production line and quality control links of electronics, semiconductor, solar photovoltaic and other industries. It uses the principle of electroluminescence (EL) to make the defects and microstructure of the measured object appear in the form of visible light through a specific excitation light source, so as to achieve fast and accurate detection of material quality and process level.
The core components of the EL vision inspector include the excitation light source, optical system, image acquisition and processing system, etc. The excitation light source usually uses a specific wavelength of light, such as high-energy ultraviolet or blue light, which can penetrate the object under test and excite electrons inside the object, resulting in electroluminescence. The optical system collects and transmits the emitted light to the image acquisition system, which produces clear, high-resolution images. The image acquisition and processing system is responsible for digitizing the acquired images, extracting information about defects and microstructures, and generating visual inspection results.
Portable EL vision inspectors offer a variety of benefits. First of all, it is a non-contact inspection method that does not cause any damage to the object being measured. Second, it has high sensitivity and resolution, enabling the detection of small defects and structural changes. In addition, it is fast, simple, and easy to operate, making it suitable for rapid inspection and quality control on the production line. Finally, portable EL vision inspectors have a wide range of applications and can be adapted to different types of materials and processes.
In the electronics industry, portable EL visual inspectors are often used to detect internal defects and microstructures of electronic components such as semiconductor chips, integrated circuits, and LEDs. In the solar photovoltaic industry, it is widely used in the inspection and production process control of solar panels. In addition, in the fields of materials science and biomedicine, portable EL vision inspectors are also playing an increasingly important role.
In short, the portable EL visual inspector is an efficient, accurate and practical non-destructive testing equipment, which is of great significance for improving product quality and production efficiency. With the continuous development of science and technology, it will be applied and promoted in more fields.
