PT TECH. Business Summary

PT TECH (3518.TW) operates as a premier provider of Physical Vapor Deposition (PVD) vacuum coating solutions, deriving the vast majority of its revenue from Electromagnetic Interference (EMI) shielding services for the global notebook computer market. Holding a dominant 50% global market share in this niche, the company provides critical protective coatings for major ODMs, supplemented by a specialized segment in decorative PVD appearance plating for automotive components and consumer electronics. By early 2026, PT TECH has significantly diversified its revenue model through a strategic pivot into the third-generation semiconductor industry, specifically the manufacturing of 6-inch and 8-inch Silicon Carbide (SiC) substrates via its subsidiary, Jingcheng Materials, at its newly commissioned Chiayi facility. Its primary direct competitors include Ichia Technologies, Catcher Technology, and Nan Pao Resins; PT TECH distinguishes itself through its massive production scale in PVD-based EMI solutions and its aggressive vertical integration into power semiconductor materials. The leadership team is anchored by Chairman Kenny Huang (黃逸駿), who represents the major shareholder Jundong International Investment and has overseen the company’s recent capital expansion into semiconductor manufacturing. General Manager Cathy Yu (游秀屏) leads the operational execution, focusing on R&D for advanced sputtering technologies and the integration of SiC wafer processing lines at the company's Chiayi and Nankan facilities. The executive suite is further supported by CFO and spokesperson Liu Ming-Yi (劉明怡), who manages the firm's strategic financial planning and investor relations. The board of directors maintains a strong emphasis on technical innovation and ESG-compliant "dry" coating processes, reflecting a pedigree rooted in Taiwan’s high-precision electronics and materials science sectors.
