The transparency of three anti-corrosion glue, an electronic chemical, provides a direct observation path for optical inspection of electronic components. Optical inspection equipment identifies details such as solder joints and circuits of components by light penetration or reflection. If three anti-corrosion glue is opaque, it will completely block the line of sight, making it impossible to conduct inspection. Transparent three anti-corrosion glue allows light to pass through smoothly, and the inspection equipment can directly observe the status of the components under the glue layer. Inspection can be completed without removing the glue layer, providing the basic conditions for the implementation of optical inspection, which is its most direct positive effect on inspection.
Three anti-corrosion glue with good transparency can reduce light refraction and scattering, and improve the clarity of optical inspection. The refractive index of high-quality transparent three anti-corrosion glue is close to that of air, and light will not be significantly deflected when passing through, and the details of the component surface can be clearly presented in the inspection image. If there are impurities in the glue layer or the transparency is insufficient, the light will scatter in the glue layer, resulting in blurred inspection images and difficulty in identifying subtle defects. High transparency ensures the stability of light transmission, allowing inspection equipment to capture more realistic component status and improve the accuracy of inspection.
For micro components encapsulated under the glue layer, the light transmittance of transparent three-anti-corrosion glue enables it to be completely scanned by optical inspection equipment. Many electronic components are small in size, such as pins on chips and micro capacitors, and require high-precision optical equipment for comprehensive inspection. After being covered with transparent three-anti-corrosion glue, it will not block the scanning light, and the equipment can image every corner of the component to ensure that there is no blind spot for inspection. This comprehensiveness avoids missed inspections caused by the obstruction of the glue layer, and can promptly discover hidden problems such as virtual connection of solder joints and broken lines, thereby improving the integrity of inspection.
The yellowing resistance of transparent three-anti-corrosion glue ensures the reliability of optical inspection after long-term use. Some glue layers will gradually turn yellow after long-term use or in high temperature environments, affecting transparency. Even if they are transparent at the beginning, they may interfere with optical inspection in the later stage. The transparent three-anti-corrosion glue with anti-yellowing properties can maintain good light transmittance during the life cycle of the component. Whether it is the initial inspection during production or the maintenance inspection after use, it can enable optical equipment to accurately identify the status of the component and ensure the consistency and reliability of the inspection results.
Transparency allows optical inspection to take into account both the component status and the quality of the glue layer, thereby improving inspection efficiency. During the inspection process, it is necessary not only to check the component itself, but also to confirm whether the three anti-corrosion glue is applied evenly, whether there are bubbles or leaks. The transparent glue layer allows the inspection equipment to observe the status of the component and the glue layer at the same time, and both inspections can be completed in one inspection. There is no need to conduct component inspection and glue layer inspection separately, which reduces the inspection steps, saves time, and indirectly improves the overall inspection efficiency.
For components that require multiple optical inspections, the repeatability of transparent three anti-corrosion glue is an obvious advantage. Some electronic components need to go through multiple inspection processes during the production process. If the glue layer is not transparent, the glue layer needs to be removed before each inspection and re-applied after the inspection, which not only increases the workload but also may damage the component. Transparent three anti-corrosion glue allows multiple optical inspections to be carried out without destroying the glue layer, maintaining the continuity of the component protection status, while avoiding damage to the component caused by repeated processing, and ensuring the safety of the inspection.
The light transmittance of transparent three anti-corrosion glue can adapt to the high-speed operation of the automated optical inspection system. Automated inspection relies on machine vision to quickly identify defects, requiring the glue layer to have minimal obstruction to light, ensuring that the image acquisition speed matches the recognition algorithm. The transparent glue layer does not delay light transmission or increase the complexity of image processing, allowing the automated system to complete the inspection process at high speed and meet the requirements for inspection efficiency in large-scale production. This adaptability makes transparent three anti-corrosion glue an indispensable auxiliary material in automated optical inspection systems, promoting the efficient application of inspection technology in the electronics manufacturing industry.
