What Sandtek does

Sandtek (胜达克半导体) is a Shanghai-headquartered Chinese designer and manufacturer of semiconductor Automatic Test Equipment (ATE), operating as a privately-held joint-stock company under the legal name 胜达克半导体科技(上海)股份有限公司. The company's core product platform is the AdaptStar family, which spans five modular ATE systems (AdaptStar D, A, H, Q, and E) ranging from a lightweight 500Mbps digital test system to a high-end configuration with 16 module slots and 2,048 digital channels, all built around a floating ground architecture and elastic CP connection structure that enable high-voltage superposition, current merging, and low-noise precision measurement for SoC, MCU, digital, and mixed-signal IC testing. Complementary products include the IntroStar dedicated open-short tester (up to 8,192 channels) and interchangeable functional modules (DIGI digital signal, MIXI-2 mixed signal, DPSI multi-channel DC power, MVPI medium-high voltage power).

The company serves Chinese and East Asian semiconductor manufacturers and design houses across application verticals including computers, wearables, communications, office automation, intelligent transportation, automotive electronics, home appliances, and industrial automation. Sandtek generates revenue primarily through hardware sales of ATE systems and modular components, with pricing negotiated on a per-project enterprise basis (no public pricing disclosed). Its go-to-market is direct enterprise field sales supported by regional offices in Shanghai, Suzhou, Chengdu, Xi'an, and Shenzhen, supplemented by wholly-owned subsidiaries in Japan and Malaysia; the Malaysia subsidiary achieved its first overseas factory equipment shipment in 2026. Marketing is concentrated in industry events, principally SEMICON China and SEMICON SEA, alongside a WeChat official account and academic engagement via IC design competitions.

Sandtek has accumulated regulatory and quality credentials including ISO9001:2015 (2018), High-Tech Enterprise recognition (2021), Shanghai High-Tech Achievement Transformation Project recognition (2022), and the National-level Specialized, Refined, and Innovative 'Little Giant' enterprise designation (2022). It has raised approximately $14.75 million in a single disclosed funding round in August 2022 from Huaye Tiancheng Capital, Panorama Capital, and Yongxi Capital. The company self-describes as a global leading IC testing equipment supplier, though no revenue, headcount, or installed base data is publicly disclosed.
