The Tricks Of Copper Terminal Blocks: Falsely Labeled Plating Thickness

Comparing industry standards and actual measurement results reveals that the plating values ​​listed in the manufacturer's instructions for component copper terminal block are often close to the lower limit of the standard, or the measurement methods are not in accordance with generally accepted standard specifications. The industry typically refers to industry standards to set plating thickness requirements; for example, the common tin plating thickness for connector contacts is in the micrometer range, affecting contact life and electrical performance.

copper distribution block undertakes the tasks of carrying current and connecting in electrical systems. Different metal platings (such as tin and nickel) are used to deal with environmental factors and contact interface problems. The thickness of copper terminal strip not only affects oxidation resistance, but also relates to long-term reliability performance. While copper substrates themselves have high conductivity, the actual effective contact area and corrosion resistance are only realized after plating treatment.
