BS EN 61189-2-719:2016

What is BS EN 61189-2-719 - Relative permittivity and loss tangent about?   

BS EN 61189-2-719 is an international standard that covers test methods for electrical materials, printed boards, and other interconnection structures and assemblies.  The main objective of the BS EN 61189 series is to demonstrate the reliability of laminate materials and assemblies and avoid printed circuit board failures.  

BS EN 61189-2-719 specifies a test method of relative permittivity and loss tangent of the printed board and assembly materials, expected to be determined 2 to 10 of relative permittivity and 0.001 to 0.050 of loss tangent at 500 MHz to 10 GHz. 

Who is BS EN 61189-2-719 - Relative permittivity and loss tangent for?  

BS EN 61189-2-719 on relative permittivity and loss tangent is useful for:  

• Manufacturers of electronic devices 
• Manufacturers of printed circuits and boards 
• Quality testing agencies 
• Electronics industry 
• Electronic engineers 

Why should you use BS EN 61189-2-719 - Relative permittivity and loss tangent?   

Relative permittivity is essential information to have when building capacitors and other materials that are expected to introduce capacitance into a circuit. The loss tangent is a measurement of signal loss caused by the dissipation of electromagnetic energy in the printed circuit board's substrate. 

Relative permittivity and loss tangent are detailed in BS EN 61189-2-719 to evaluate signal attenuation and to ensure that all-important information is recorded over the appropriate frequency range to accurately capture the magnitude of the resonances' peaks.  

With the help of BS EN 61189-2-719, you can find the frequency, measurement point, averaging number, and smoothing level, as well as increase the signal-to-noise ratio. 

Overall, BS EN 61189-2-719 will assist you in providing an alternative method for quantifying the effect of loss on an electromagnetic field within a material.
