Above is a smooth finger spring product. The design focus of this series is to eliminate all protruding structures and strive for a completely smooth surface. This is primarily to enhance the consistency of mating surfaces, thereby improving the overall structural operational safety. Of course, it also serves the purpose of matching the surface finish of products or equipment, such as being used in the surface gaps of various shielding cabinets, where it can provide both shielding and grounding functions without affecting the overall appearance of the equipment. Therefore, this type of product uses pressure-sensitive adhesive bonding for installation, without any protruding clip structures. Additionally, this series of beryllium copper spring fingers can be customized with various electroplating processes, such as bright nickel, bright tin, and zinc chromate plating, further satisfying the surface compatibility requirements of customers. In terms of structure, the smooth finger spring series can be divided into two main categories, which are briefly introduced below.

Above illustrates the smooth finger spring series with a triangular cross-section. The design of this cross-sectional structure primarily targets environments with bidirectional shear stresses, enabling the decomposition of tangential or oblique stresses into normal stresses for bearing as much as possible.

The image above showcases the smooth finger spring series with a thin cross-section. It features the same D-shaped cross-section, but with a lower contact surface height, making it suitable for applications with low compression stress and limited height.

In terms of materials, the Smooth Series offers two options: beryllium copper and stainless steel. The beryllium copper springs are high-performance products, boasting exceptional tensile strength and conductivity, making them ideal for applications with high-performance requirements. The stainless steel springs, while slightly inferior in performance to the beryllium copper counterparts, are more economical and still offer decent performance, making them suitable for cost-effective applications.
