A. Deutsch et al., BROAD-BAND CHARACTERIZATION OF LOW DIELECTRIC-CONSTANT AND LOW DIELECTRIC LOSS CYTUF(TM) CYANATE ESTER PRINTED-CIRCUIT BOARD MATERIAL, IEEE transactions on components, packaging, and manufacturing technology. Part B, Advanced packaging, 19(2), 1996, pp. 331-337
Dielectric constant epsilon(r) and broadband dielectric loss tan delta
measurements were performed for the thermoplastic toughened cyanate e
ster printed circuit board CYTUF(TM) material, Characterization of tan
delta over the 1-8 GHz frequency range was made using a simple short-
pulse propagation technique, All the measurements were taken on four-m
etal-layer, 23 x 36 cm cards with representative transmission line str
uctures, It was found the epsilon(r) = 3.48 - 3.64 and tan delta = 0.0
095 - 0.01, which are much lower than for standard FR-4 material, The
impact of improved characteristics on wireability is analyzed through
simulations of representative printed circuit board interconnections.
