What TMSC Systems Co. Ltd. does

TMSC Systems Co., Ltd. is a Bangkok-based, privately-held industrial supplier founded in 2009 that designs, manufactures, and distributes components for the semiconductor back-end test industry, with a secondary line of LED lighting products sold under its own EXCYNE brand. Its core technical offering consists of JFT test sockets for non-pogo QFN/QFP packages, ceramic spare parts engineered for 3–5 million insertion lifetimes, and a custom spare-part design and re-engineering service that lets it build bespoke parts to customer drawings. The company also operates a used semiconductor equipment trading desk and a tester/handler board repair service, and since 2024 has expanded into a multi-brand distribution platform by representing foreign partners: JFTECH manipulators and hinges, HVT (HVTEC) vacuum soldering systems, SemiGlory wafer-handling consumables, and HPRAY cleanroom piping and valves. Its customer base is concentrated in Thailand's semiconductor manufacturers, with a long-tail of industrial, hospitality, healthcare, agricultural, and residential LED buyers reached through the EXCYNE channel; GTM is direct, quote-based, and driven primarily by the company's website and inbound contact forms. Revenue model is essentially transactional hardware sales plus aftermarket services, with no disclosed financial scale and no external funding to date.
