Core offering

Sentec manufactures and supplies integrated solutions across three business units for automotive, electronics, and semiconductor industries: (1) Emission Control Solutions including air intake systems, evaporative emission control canisters/valves, and catalytic converters compliant with EU5, Taiwan Phase 7, and EPA Phase 3; (2) Electro Ceramic & Device products including LTCC substrates, ECC metallized ceramics, power electronics substrates, interposers, and turnkey semiconductor module packaging; (3) Mechatronics Foundry Services including SMT assembly, motor and controller integration, ISG controllers, simulation, and dynamometer/environmental testing for EV and green technology applications.

Product overview

Sentec offers an integrated portfolio of three main solution areas spanning the automotive, electronics, and semiconductor industries since 1968. The Emission Control Solutions division provides air intake systems, evaporative emission control systems (EEC), and exhaust after treatment systems with catalytic converters. The Electro Ceramic & Device division delivers LTCC substrates, power electronics ceramic solutions, photonic/thermal electric components, interposer substrates, and turnkey semiconductor module packaging OEM services. The Mechatronics Foundry Service division offers material selection, simulation services, SMT assembly, motor & controller integration, and testing/verification services. These three divisions work together to provide integrated solutions from manufacturing materials to devices and systems, with a focus on reducing global CO2 emissions.
