Why Gold Plating?

To meet the application scenarios with extreme requirements for electrical connections, gold-plated metal domes provide key performance assurance. Although stainless steel itself has certain anti-oxidation properties, the chromium oxide layer formed on its surface may affect conductive stability. Compared with conventional treatments such as nickel plating, professional gold plating not only completely prevents substrate oxidation but also endows the metal dome surface with excellent and long-lasting conductive performance. This superior conductivity and protection, combined with high-quality metal dome base material, are crucial for high-specification products that require extreme reliability and long-term stable operation, ensuring error-free signal transmission.

Professional gold plating process details

What is Professional?

Professional gold plating technology goes far beyond material selection; it is reflected in the profound understanding and precise control of complex metallurgical issues. For example, addressing the hydrogen embrittlement phenomenon that stainless steel is prone to during traditional electroplating processes – which can lead to reduced adhesion of the plating layer and damage to material toughness, thereby significantly shortening product lifespan – we employ advanced gold plating techniques that circumvent the risk of hydrogen embrittlement. This ultimate pursuit of process details ensures a dense, uniform, and firmly adhered plating layer, fundamentally guaranteeing the high reliability and ultra-long mechanical life of the metal domes, meeting the most stringent application standards.

Precision Double-Layer Film Lamination Process

This high-quality metal dome film array utilizes a precision double-layer film lamination process. Its structural feature is the integration of a special spacer layer beneath a protective cover film (such as Mylar® material). This critical spacer layer design provides a tight physical barrier for the internal metal domes, effectively blocking the intrusion of environmental dust particles and significantly slowing down the oxidation process of metal components.

Through the excellent protection provided by this double-layer structure, the contact points of the metal domes are kept clean, thus ensuring high stability of electrical connections and long-term reliable conductive performance. In addition, the carefully designed ventilation groove structure in the array not only helps to optimize air circulation during key operation but also plays a positive role in enhancing the tactile feedback and consistency of the keys, bringing users a better operating experience.
