(II) Core features
1. Precision adaptation: Five-axis CNC machining ensures the accuracy of positioning columns and openings, and seamlessly fits with electronic modules. The installation error is ≤0.05mm, ensuring the consistency of component integration and reducing signal transmission interference.
2. Strong protection: Stainless steel material is naturally resistant to electromagnetic interference, and with a passivated surface, it effectively shields external electromagnetic pulses, while resisting erosion by humid, acidic and alkaline environments, extending the life of the equipment.
3. Structural reinforcement: The one-piece molding process creates a high-strength substrate that can carry more than 10kg of electronic modules, does not deform under vibration and impact conditions, and ensures long-term stable operation of the equipment.
III. Product details
This component focuses on the research and development of precision integration needs of electronic equipment. Selected 304/316L stainless steel sheets are cut by laser, and then milled, drilled and tapped by a five-axis linkage CNC machining center to achieve integrated molding of positioning columns and functional structures. The surface is chemically passivated to form a dense oxide film to improve corrosion resistance and insulation performance (silver plating/nickel plating can be selected to enhance conductivity).
In industrial control equipment, it is used as a mainboard substrate to accurately fix chips, capacitors and other components to accelerate heat conduction; when used in communication base stations, it shields radio frequency interference to ensure signal purity. The entire production process is inspected, the three-coordinate measuring instrument controls the form and position tolerances, and the salt spray chamber verifies the corrosion resistance. From the automation control system of the smart factory to the high-frequency communication module of the 5G base station, this stainless steel precision electronic component is precisely manufactured, strongly protected, and highly reliable, building a "stable skeleton" for electronic equipment and promoting the development of high-end electronic equipment towards miniaturization and high integration.
