Emerging end-use electronic applications are driving dramatic innovations in circuit board and interconnection technology. New form factors, functionality and durability requirements are challenging the status quo for the PCB industry and pushing design, material and process development to the limit.

Currently there is no industry standard test method for measuring dielectric properties of circuit board materials at frequencies greater than about 10 GHz. Various materials vendors and test labs take different approaches to determine these properties. It is common for these different approaches to yield varying values of key properties like permittivity and loss tangent.
