What Fatdi Precision Technology does

Fatdi Precision Technology (legal name: Suzhou Fatedi Technology Co., Ltd. / 苏州法特迪科技股份有限公司, doing business as FTDevice) is a Chinese privately held supplier of consumable hardware solutions for semiconductor packaging and testing. Founded in 2014 and headquartered in Suzhou Industrial Park, the company designs, develops, manufactures, and assembles semiconductor test interface products — principally test sockets (5G/RF, standard, high-power, MEMS/sensor, conductive rubber, J-type scrub RF, burn-in, and independent temperature-control variants), aging temperature control systems, and automated test sorting machine kits. Technical specifications include 80GHz/224Gbps high-frequency bandwidth, 50Ω impedance matching, three-temperature testing from -55°C to 175°C, support for chip power up to 1000W, lead pitch down to 0.15mm, and pin counts exceeding 3,000, alongside coverage of advanced packaging test formats including CoWoS, Chiplet, and 3D IC.

The company's customer base spans global chip design enterprises, packaging and testing manufacturers, and test equipment suppliers, with reported 300+ cumulative service cases and dozens of Fortune 500 semiconductor customers. Go-to-market is direct enterprise B2B sales with quote-based custom pricing on specialized hardware. Revenue mechanics are dominated by one-time hardware sales (custom and standardized test sockets, aging systems, ATE kits) supplemented by professional engineering services for thermal, force, and electromagnetic/RF analysis. The company holds over 100 authorized patents, has been designated a national-level key 'Little Giant' enterprise, and operates R&D and design centers in Suzhou and Wuhu alongside a manufacturing subsidiary, Blueluster Semiconductor (蓝泽半导体), in Wuhu Wanzhi District. Fatdi is reported to rank in the top 10 globally in market share in the test socket sector per industrial research institutions, and completed an undisclosed new financing round in December 2025 with Yongxin Ark, Shenzhen Venture Capital, and Suzhou High-tech Investment.
