What YJ Link Co. does

YJ Link Co., Ltd. is a South Korea-based manufacturer of SMT (Surface Mount Technology) process automation equipment, founded in 2009 and headquartered in Daegu. The company supplies a full SMT line portfolio covering PCB handling (Y-Series standard, P-Series premium PC-controlled, E-Series economy, VF-23 Southeast Asia strategic), PCB depaneling routers (ARMAS Router Platinum with dual spindles and vision camera), laser marking (NOVLUX with CO2 head and dual-side inversion), in-circuit functional testing (IFCT with measurable cycle-time and fixture-cost reductions), and — most recently — autonomous material handling via the YGV Autonomous Mobile Robot with LiDAR-based navigation and sub-10mm positioning accuracy. The product set supports both individual equipment sales and the SMT Full Line turnkey business launched November 2024, which bundles CAPA analysis, substrate and process design, data system configuration, and full equipment supply for new line construction projects.

The company sells primarily through direct enterprise engagement with global tier-1 customers, supported by a permanent showroom in Suwon, participation in major industry exhibitions (NEPCON, Productronica), and localized sales/CS offices. Over 90% of revenue is export-oriented, with named customers spanning electric vehicles and aerospace (Tesla, SpaceX), EMS and consumer electronics (Foxconn, Harman International), automotive electronics (Hyundai Mobis, Hyundai Motor's K-supplier, KOSTAL), and semiconductor packaging (ASE). Contract wins include a Foxconn India PCB conveyor deal (~USD 1.67M), an SMT Full Line project for a Hyundai Motor K-tier-1 partner (~KRW 2.6B), and Hyundai Mobis router supply following December 2025 supplier registration.

YJ Link completed its KOSDAQ IPO in October 2024 and deployed proceeds into global production base expansion: existing Vietnam subsidiary (YJ Link VINA, Haiphong, ~500 units/month since 2019), a new Mexico factory completed August 2025 in Guadalajara (~300 units/month, 7,272 sqm facility, planned offices in Chihuahua/Monterrey/Queretaro), and an India production entity groundbreaking in January 2026 (Bengaluru). Combined monthly SMT equipment capacity is approximately 1,000 units across the three operating hubs. Reported FY2023 revenue was ~KRW 485 billion (~USD 365M) with ~KRW 91 billion operating profit; 5-year revenue CAGR was 8.2% and operating profit CAGR 29.5%. More than 50% of revenue derives from global tier-1 customers with revenues exceeding KRW 1 trillion, indicating a high customer concentration profile offset by long-cycle equipment sales with 3-year standard warranties and ongoing after-sales service revenue.
