With the rapid development of information technology, various complex information devices have brought convenience to people's lives. However, along with this comes the problem of electromagnetic information leakage and interference, which affects people's ecological environment. Therefore, people have begun to use various shielding materials to shield electromagnetic information and prevent information leakage and interference. Then what are the standards for performance testing of Conductive tape for SUS mounting plate BeCu gasket? What kind of material can shield electromagnetic information?

1. shielding tape for SUS mounting plate BeCu gasket what are the performance detection methods?

1. Small shielding body window test method

The principle of this is also relatively simple. It is basically the same as the testing method for the window of a shielded room. Generally, to avoid any impact during the test, it is chosen to be conducted in an open area. The applicable frequency range is 1GHz to 18 GHz.

2. Franck coaxial device test method

The flange coaxial device can be understood as providing a uniform planar measurement environment when the transmission line is small, mainly based on the equivalent circuit principle for testing. The flange coaxial device test method is applicable within a frequency range of 30 MHz to 3 GHz, with a dynamic signal reception range up to 120 dB. It features good repeatability and is suitable for measurement during online quality control of products.

Ii. What are the criteria for performance testing of Conductive tape for SUS mounting plate BeCu gasket?

The testing standards for the shielding effectiveness of equipment and facilities are:

GJB 6785-2009 "Test Method for Shielding Effectiveness of Military Electronic Equipment Cabins"

GB/T 12190-2006 "Measurement Method for Shielding Effectiveness of Electromagnetic Shielded Rooms"

The test standards for the shielding effectiveness of systems and complete machines are:

GJB 5362-2005 "Measurement Method for Shielding Effectiveness of Missile Enclosures"

GJB 5185-2003 "Measurement Method for Shielding Effectiveness of Small Shielding Bodies", etc

The test criteria for the performance of Conductive tape for SUS mounting plate BeCu gasket mainly include:

GB/T 30142-2013 "Planar Electromagnetic shielding Conductive tape for SUS mounting plate BeCu gasket performance measurement method"

GJB/Z158-2011 "Data Manual on Electromagnetic Shielding Performance of Electromagnetic Materials for Military Equipment"
