Test methods for electrical materials, printed boards and other interconnection structures and assemblies - Test methods for materials for interconnection structures. Relative permittivity and loss tangent (500 MHz to 10 GHz)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
