1570 - Conductive Shielding Gasket Silicone PCB

1570 series PCB Shielding Gaskets

“SMwall series” is Surface Mountable Technology(SMT) compatible electric elastomer connector. “SMwall series” has good elastic recovery and electric property, so it offers not only cushion, but also electrical connecting and grounding between electrical objects and PCB. “SMwall series” is a rectangle with narrow width and is mounted on PCB board. So this can replace Shield Can or EMI Dispensing Gasket or other electric contacts. Recommendation of compression is 10~30% of its height.


Main characteristics

  • Suitable for EMI shielding and grounding.
  • Lower electric resistance.
  • Meet to most salt spray and environmental test.
  • Good resilient & recovery property. Easy to apply SMT.
  • Strong soldering strength and not easy to detach on PCB.
