What Tong Hsing Electronic Industries does

Tong Hsing Electronic Industries, Ltd. (同欣電子工業股份有限公司, TWSE: 6271) is a Taiwan-based ceramic substrate and semiconductor micro-module packaging manufacturer founded in 1974 and headquartered in Bade District, Taoyuan City. The company operates a platform-plus-modules architecture across four product categories: (1) ceramic metalized substrates including DPC (Direct Plated Copper), DBC (Direct Bonded Copper), AMB (Active Metal Brazing), and thick film printed circuit substrates; (2) CMOS imaging products and module packaging; (3) power semiconductor and RF/high-frequency wireless communication module packaging; and (4) customized packaging and testing services spanning wafer probing, backgrinding, wafer reconstruction, assembly, automated inspection, and finished module testing. Proprietary metallization and brazing processes combine ceramic thermal management with copper conductivity for high-power, high-reliability applications.

The company's revenue model is B2B hardware sales of ceramic substrates plus professional services revenue from customized packaging and testing. End markets include automotive electronics (ADAS image sensors, EV power modules, IGBT, inverters, charging systems), consumer electronics (smartphone CMOS image sensors, 3D sensing, fingerprint recognition), wireless communications (RF modules, satellite communications), LEDs and lighting, aerospace, medical electronics, and semiconductor equipment. The company sells directly to enterprise customers worldwide, with manufacturing operations across Taiwan (Yingge, Bade, Longtan, Zhubei) and the Philippines, and a new 89,000 sqm Bade Plant under construction to add 2,300+ jobs.

Tong Hsing is a subsidiary of Yageo Corporation (國巨集團), following the 2019–2020 merger with Kingpak Technology Inc. (勝麗國際, TWSE: 6238), a leading automotive CMOS image sensor packaging company. The combined entity serves as Yageo's platform for automotive electronics, industrial products, 5G, and IoT packaging. In 2021, the company received Taiwan's 6th Outstanding Backbone Enterprise Award from the Ministry of Economic Affairs, and in 2022 underwent a generational leadership transition with CS Chang (張嘉帥) appointed General Manager.
