In the post-pandemic era coupled with the development of industrial automation, factories are reorganizing their workforce to ensure the best use of it.

When a traditional factory is transferred to a smart factory, more devices will be adopted to improve production performance. The vision machine system is undoubtedly one of the important devices, and the automated optical inspection (AOI) is the eye of the first step in quality control.

AOI integrates with optics, mechanics, electronic control and software to replace the human eye and the camera will autonomously scan the device under test for both catastrophic failures and quality defects.

Challenges and requirements

Quality inspection is a critical step in the entire production flow. Traditionally, quality inspection was handled by manual visual inspection (MVI), using humans to detect defects. Today, in the post-pandemic era coupled with the development of industrial automation, factories are reorganizing their workforce to ensure the best use of it. Obviously, more and more workers will be replaced by machines, especially in labour-intensive industries. For example, factories use artificial vision to replace human vision, artificial intelligence instead of the human brain. This replacement accelerated the practice of AIOT.

When cameras capture images during the inspection process, these images should be transmitted to AOI systems with stability. What we call “stability” means that all data can be transmitted at high speed without dropping frames, without any form of image distortion, and without transmission interference. In addition, AOI systems must operate 24/7 and maintain the same output quality in different environments, then inspection capacity will be maximized.

What can Cervoz offer?

Optimized stability and performance solution in a 24/7 factory

To ensure stabilized transmission, including processing huge amounts of small images, Cervoz offers a endurance-optimized industrial flash solution which meets the requirement to quickly and accurately write large amounts of small-sized data to SSD. A built-in flash DRAM module provides a temporary storage area for data and the chip acts as a directory that helps allocate data to assigned positions which could improve performance by shortening the transmitted response time of data, simultaneously increasing the endurance by reducing P/E cycle erase time.

Overcome extreme environment service

Cervoz provides a Conformal coating service for all DRAM and flash modules, allowing them to be protected by the thin protective film against moisture, dust, chemicals, for example, in food processing plants where the use of AOI for filing and inspection in the wet and cold working environment. It not only improves the reliability of the product, but also extends the life of memory and storage. When it comes to extreme environments, Cervoz products use industrial-grade ICs with strict compatibility testing to ensure reliability can operate in extreme temperatures ranging from -40˚C to 85˚C.

Prevent power outages from crashing the system

Cervoz Powergard (power loss protection, PLP) The technology can prevent the continuous loss of written data and ensure the stability of data transmission in the event of a power failure. Cervoz Powregard as well as power stability, needless to say, essential for plants operating 24/7.

Cervoz offers a rich portfolio of high performance DRAM module solutions and storage products for various industrial applications. Contact Cervoz for more industrial solutions.
