SMT Gasket
Overview
- This product shields electromagnetic noise (EMI) and grounds simultaneously by using metal-plated PI film with excellent electric conductivity and flexibility.
- Possible to process reflow soldering by using PU sponge which is excellent in heat resistance and elasticity, and can be used as a cushioning material because of its excellent restoring force.
- It is soldered to PCB and packaged with reel tape for automatic mounting (SMT).
- It can be customized in various sizes and shapes.
Features
- RoHS Compliant
- UL94V-0, Halogen Free
- Low surface resistance
- Excellent resilience, free from bent or broken problem (Hardness adjustable)
- SMT available and manual soldering compatible
