Koh Young True 3D Inspection with KSMART AI Solutions

Koh Young Technology is a Korean inspection equipment maker founded in 2002 and headquartered in Seoul. It supplies True 3D solder paste inspection (SPI), automated optical inspection (AOI), semiconductor, dispensing and final optical inspection systems for electronics assembly, and reports more than 3,800 customers and over 24,000 installed machines.

On top of its 3D measurement hardware, Koh Young offers Smart AI Solutions under the KSMART ecosystem. KAP (Koh Young Auto Programming) uses accumulated True 3D data and deep learning to generate inspection programs automatically, Smart Review applies on-device AI to judge defects and filter false calls, and KPO Printer and KPO Mounter analyse process data to adjust printer and mounter settings. The aim is to shorten line setup, stabilize yield and connect inspection data across SMT processes.

• True 3D measurement: SPI and AOI systems measure solder and components in three dimensions, reducing the effect of board color and lighting.
• KAP auto programming: generates inspection programs with AI from package libraries and verified presets.
• Smart Review: judges defects on the device with AI and feeds tolerance adjustments back to inspection.
• KPO Printer and KPO Mounter: analyse process data and adjust printer and mounter parameters automatically.
• KSMART analytics: turns inspection results across processes into data for process control.
• Broad inspection range: covers SMT, semiconductor packaging, dispensing and final optical inspection.

An EMS plant in Bac Ninh or Hai Phong could use KAP to program inspection for new board models within hours. A component supplier could apply Smart Review to cut false calls that slow down operators. A semiconductor packaging line could add 3D inspection for bumps and dies with linked process analytics.

KAP cuts inspection programming time by up to 90%, with an average mapping rate above 90% and 100% library reuse in customer applications, according to Koh Young. On-device AI review reduces false calls and makes judgments consistent across operators. Automatic process optimization lowers manual tuning and trial-and-error on SMT lines.

Vietnam is one of the largest electronics assembly hubs in Asia, with Korean, Japanese and Chinese EMS and component makers expanding SMT lines in the north. As board complexity rises and experienced programmers are scarce, AI-assisted programming and review on inspection equipment help new lines reach stable yield faster.

Koh Young Technology was founded in 2002 in Seoul and says it has led the inspection market since 2006. It operates Koh Young Vietnam in Cau Giay, Hanoi, a Vietnam Software R&D Center, and Koh Young SE Asia offices in Singapore, Penang and Thailand. In November 2025 it showed new AI and inspection products at Productronica and SEMICON Europa.
