Nihon Koshuha WEC-029NX50.190ST1 Microwave Waveguide TEL Trias CVD Plasma Spares

The Nihon Koshuha WEC-029NX50.190ST1 is a high-precision microwave waveguide component engineered for advanced semiconductor processing tools. Manufactured in Japan by Nihon Koshuha (NKK), this waveguide is a critical spare for Tokyo Electron (TEL) Trias series CVD (Chemical Vapor Deposition) and Etch platforms.

The WEC series is designed to facilitate the low-loss transmission of high-frequency microwave energy to the plasma source. Given the extreme precision required for plasma uniformity in wafer processing, the internal surfaces and flange alignments of the WEC-029NX50 are manufactured to exacting tolerances. This component is essential for maintaining stable plasma discharge and preventing reflected power issues that can lead to RF generator damage or process instability.
