In recent years, with the accelerated mass production of smart vehicles, demand for optical structural components such as in-vehicle displays, smart rearview mirrors, and large-size center console glass has surged rapidly. The market has imposed increasingly stringent technical requirements on optical coating equipment capable of large-area, high-uniformity, and stable mass production. Simultaneously, the semiconductor advanced packaging sector continues to evolve driven by TGV 3D structure technology, creating an urgent need for coating capabilities targeting complex through-holes with high aspect ratios. Equipment faces sustained pressure to upgrade in process precision, window width, and material compatibility.
Driven by these dual industry forces, high-performance vacuum coating equipment has become a critical enabler of industrial upgrading. To showcase its latest engineering achievements, Zhenhua Vacuum presented a comprehensive lineup of core products at the 2025 Guangdong Vacuum & Semiconductor Exhibition from November 13–15. The company demonstrated its coating solutions across optical components, advanced packaging, and electronic component manufacturing. The booth attracted significant attention from professionals in optoelectronics, packaging, and automotive manufacturing, generating strong technical exchanges and clear cooperation intent.
