Ionic purity

Recent work (7) which repeated Licari s tests used a large number of commercially available conductive inks and adhesives to determine the effect of resin-type, of Tg, of ionic purity and of... [Pg.268]

Polyimides Higher temperature stability compared to epoxies. High ionic purity. Reduced bleedout. Trapped solvent can produce voids under large ICs. Multi-step curing required to volatilize solvent. High-stress materials. May absorb moisture in cured condition. Cannot be B-staged. [Pg.122]

Xi process. At the lowest frequencies and high temperatures there is an increasing low frequency loss and the permittivities reach very large values " (up to 10 ). The permittivity a (v) and loss factor 6"(v) follow the and v" laws respectively and such behaviour is interpreted in terms of the diffusion of ionic species. " " " This process is very dependent upon the ionic purity of the material. [Pg.624]
