摘要:
Conductive powder and paste compositions are formed having desirable electrical and physical properties. The conductive powder and paste compositions may be used in combination with dielectric powder and thick-film paste compositions, which are formed having high dielectric constants, low loss tangents, and other desirable electrical and physical properties, to form capacitors and other fired-on-foil passive circuit components.

An organic encapsulant composition applied to formed-on-foil ceramic capacitors and embedded inside printed wiring boards allows the capacitor to resist printed wiring board chemicals and pass 1000 hours of accelerated life testing conducted under high humidity, elevated temperature and applied DC bias.

摘要:
Compositions comprising: an epoxy containing cyclic olefin resin with a water absorption of 2% or less; one or more phenolic resins with water absorption of less than 2% or less; an epoxy catalyst; optionally one or more of an electrically insulated filler, a defoamer and a colorant and one or more organic solvents. The compositions are useful as encapsulants and have a cure temperature of 190° C. or less.
