Low Dielectric

AbstractAs electronic devices become faster, the effective dielectric constant of the circuit packaging connecting them becomes more important. The dielectric constant of standard epoxy/glass laminates can be significantly reduced by the addition of hollow glass microspheres. However the addition of such microspheres usually results in the degradation of other physical, electrical and mechanical properties which are prerequisites for materials to be used in commercial circuit packaging. By carefully optimizing the formulation many of these undesirable effects can be avoided. These topics and others pertaining to the development and testing of a microsphere laminate are discussed.

AbstractA variety of low dielectric constant composites have been made into films and characterized. These composites were blends of liquid crystalline polymers (LCPs), hollow glass spheres (HGS) and polytetrafluoroethylene (PTFE). By adjusting the percentage compositions of the various components of the composites, the dielectric constant could be adjusted in the range 2.4 to 3.4. Measurement of the dielectric constant by Time Domain Reflectometry (TDR) and Frequency Domain Reflectometry (FDR) are discussed. Dielectric anisotropy is also discussed. The experimentally observed results are compared with those derived theoretically.
