Principle


EMI shielding, of high importance in the electronics industry, measures the effectiveness of a material to protect signals from being disrupted by external electromagnetic signals, as well as preventing generated signals from interfering with surrounding components.


Capabilities


20KHz - 1.5GHz

  • ASTM D149 (AC voltage)
  • ASTM D3755 (DC voltage)
  • 4" square sample or larger (thicker samples are tested in oil bath to avoid corona arcing)
  • Testing temperatures (lab ambient)
