Hanul Semiconductor Develops PIG Visual Inspection Equipment, Begins Domestic Deliveries

Hanul Semiconductor announced on December 9 that it has successfully developed and entered the market for glass-based phosphor (PIG) visual inspection systems, leveraging its accumulated experience in multilayer ceramic capacitor (MLCC) visual inspection and automation equipment. The company plans to use this achievement to expand its domestic business and actively target global markets.

Hanul Semiconductor has automated the traditional inspection method in which skilled workers would shine light at an angle to detect microcracks. Building on this, the company developed a high-speed multi-channel optical system capable of ultra-fast switching and imaging with multi-channel and multi-angle lighting. When combined with its proprietary artificial intelligence (AI) algorithms, this enables highly reproducible full inspections even in mass production environments. The company is currently registering patents for these core technologies.

Glass-based phosphors can stably produce high-output light even in high-temperature and high-humidity environments, leading to their increased adoption in industries that demand high reliability and durability. As a key material for laser-excited phosphor (LEP) lighting and automotive lighting, their importance is growing.

Hanul Semiconductor has enhanced inspection quality by applying its high-speed multi-channel optical system not only to general visual inspections but also to microcrack detection on surfaces, establishing a full inspection system suitable for mass production at ultra-high speeds. Additionally, by providing defect mapping and log data, the company supports process feedback and parameter optimization.

A representative from Hanul Semiconductor stated, "By implementing the inspection methods of skilled workers through a high-speed multi-channel optical system, we have ensured both the quality and productivity of microcrack inspections. Moving forward, we will gradually complete integrated process equipment covering inspection, classification, and defect removal, setting a new standard for quality control of glass-based phosphors."

The representative added, "We will expand our sales channels through global customers and agents in markets such as China and Japan. Based on establishing references-including with a domestic company B-and standardizing processes, we will pursue simultaneous growth in both sales and profits."
