Product Description
Our PCB aluminum ring heatsink is precision machined by CNC turning from solid 6063-T5 aluminum rod. After turning forming, we perform full deburring treatment before matte black anodizing surface finishing.
This circular aluminum heatsink is engineered for efficient thermal dissipation of PCB assemblies. As a professional CNC machining manufacturer, we provide flexible OEM and custom service. We can produce custom ring heat sink strictly according to your technical drawings, samples, special dimension requirements and tolerance demands.
The black anodized layer improves surface hardness, corrosion resistance and insulation performance, while maintaining good thermal conductivity of 6063 aluminum. Every cnc turned aluminum heat sink is inspected dimensionally to guarantee tight tolerance and consistent quality for your PCB cooling solution.
