SMT Gasket

  • SMT-EMI-Shielding-Gasket-and-Grounding-Contact-1
  • SMT-EMI-Shielding-Gasket-and-Grounding-Contact-2
  • SMT-EMI-Shielding-Gasket-and-Grounding-Contact-3

Overview

  • SMT Gaskets (SMT EMI Pads) protect circuits from electrical surges generated inside the device and remove electromagnetic noise.
  • Used highly conductive materials to secure circuit protection and to eliminate electromagnetic noise through PCB ground.
    (Shielding rate 70dB or more possible)
  • Reflow soldering is possible up to 260 ℃ by using material with excellent heat resistance.
  • Packaged with reel tape in bobbin for automatic mounting.
  • Good for touch sensor gasket, touch switch gasket, or grounding pads 

Features

  • RoHS Compliant
  • UL94V-0, Halogen Free
  • Low surface resistance
  • Excellent resilience, very soft and free from bent or broken problem (Hardness adjustable)
  • SMT available and manual soldering compatible
