SMT EMI SHIELDING GASKET

電洽


CHARACTERISTICS
 
  • RoHS compliant
  • UL94V-0
  • Halogen Free
  • Available in SMT/Low surface resistance
  • Soldering compatible/Hardness can be adjusted
  • Smooth Surface of the alloy foil skin allows easy replacement by a pick & place equipment, and compatible for reflow tunnel efficient mass production using surface mounting equipment electrical conductivity is superior than existing fiber type of foam gasket and finger strip gasket.
  • Excellent resilience without bended or broken problem
  • Available in conductive cushioning material as adjusting varying hardness by custom made
