At TOPKING Tapes, we understand that modern electronics manufacturing is a race for efficiency. This gold-plated EMI shielding gasket is our answer to that challenge, eliminating manual gasket installation by fully integrating into your automated pick-and-place and reflow soldering lines.
Automated Grounding for SMT Assembly
Gold-plated conductive foam gasket transforms the traditional soft gasket into a surface-mountable component. By utilizing a gold-plated conductive layer over a specialized heat-resistant polymer core, the gasket maintains its mechanical elasticity and electrical integrity even after exposure to reflow soldering temperatures. It provides a reliable grounding point that is both corrosion-resistant and mechanically robust.
Key Advantages
- SMT Process Compatible: Designed for “Pick and Place” automation. It allows you to solder a soft gasket directly to the PCB, removing the need for expensive metal clips or labor-intensive manual adhesion.
- Superior Gold Plating: The gold layer provides excellent conductivity and, crucially, superior oxidation resistance compared to standard nickel/copper, ensuring stable performance in humid or corrosive environments.
- Mechanical Resilience: Excellent recovery rate (rebound). It acts not just as a ground, but as a damper against shock and vibration, protecting the connection point.
- Shape Versatility: Available in various sizes and custom die-cut shapes to fit specific board layouts.
Reflow Soldering & Usage Tips
This component is not complex, but thermal management is key. It is fully compatible with general Lead-Free Reflow Soldering profiles.
- The 4-Stage Process: It handles the standard curve: Preheat, Soak (Heating), Reflow, and Cooling.
- Stability: The modified polymer core ensures the gasket does not collapse or lose its spring force during the brief high-heat exposure of the reflow zone.
- Design Tip: Ensure your PCB pad layout matches the gasket footprint to prevent shifting during the wetting phase of the solder paste.
Ideal Applications
- High-Volume PCBs: Smartphones, tablets, and wearables where manual assembly is impossible.
- Harsh Environments: Marine or industrial electronics requiring the anti-corrosion properties of gold.
- Vibration Sensitive Units: Automotive electronics where the gasket must maintain contact despite constant engine vibration.
