Plated Red Copper Bushing

While pure T2 red copper delivers excellent bulk conductivity, the surface condition determines real-world performance in soldering and contact applications. The quality Plated Red Copper Bushing is offered by Zenko, a professional manufacturer in China. It addresses this by applying a controlled plating layer that optimizes the surface for the intended application—whether that is soldering to a PCB, making a detachable contact, or resisting harsh environmental conditions.

The plating process begins with a precision-machined copper bushing. Before plating, the part undergoes multi-stage cleaning and activation to ensure the plating adheres uniformly. This preparation step is critical—poor adhesion leads to plating blistering or flaking during thermal cycling, which compromises both aesthetics and performance.

Choosing the Right Plating for Your Application

Tin Plating is the industry standard for solderability. A 3–15 μm tin layer prevents copper oxidation and provides a surface that solders easily at standard reflow temperatures. Zenko controls tin plating thickness to ±1 μm, ensuring consistent soldering performance across high-volume production runs.

Manufacturing Excellence at Zenko

Zenko's plating line is integrated with our CNC machining workshop, allowing us to control the entire manufacturing process from raw material to finished, plated bushing. This vertical integration means faster turnaround, better quality control, and the ability to accommodate custom requests that standalone plating shops cannot efficiently handle.

Every plated red copper bushings is accompanied by plating thickness measurement (XRF or cross-section), adhesion test results (bend test per ASTM B571), and solderability test reports upon request. For customers in regulated industries, we also provide material certificates and RoHS/REACH compliance documentation.

Where Plated Bushings Deliver Value

In PCB assembly, tin-plated red copper bushings solder smoothly and reliably, reducing voids and improving joint reliability. In RF and high-frequency electronics, silver-plated bushings maintain signal integrity by minimizing contact resistance at every interconnection point. For industrial and marine environments, nickel-plated bushings resist corrosion and maintain performance over years of operation.

Zenko works directly with design engineers to specify the optimal plating type and thickness for each application. Our engineering team can review your drawings, recommend alternatives if cost or performance can be improved, and provide samples for validation testing.
