    • A method for producing ceramic tape used to fabricate electronic devices while eliminating continued shrinkage of the unfired tape. Chemical agents are added to a mixture of ceramic powder and binder to manipulate the crosslinking of the binder. A first approach involves promoting the crosslinking reaction to completion quickly. The second approach involves preventing the crosslinking reaction during the tape slurry mixing and casting processes. A solvent is used to accelerate the crosslinking of the binder in which the solvent may include one or more of acetone, acetylacetone, toluene and ethanol. Preferably, the solvent is a combination of acetone and acetylacetone. A polyhydroxy compound, such as glycerine, may be added to accelerate the crosslinking reaction of the binder. The boron in the tape may alternatively be rendered inoperative as a crossing agent for the binder by pre-reacting the boron with the Lewis base prior to contact with the binder. The preferred Lewis base is an organic amine, such as piperidine.
    • 一种制造用于制造电子装置的陶瓷带的方法,同时消除未烧结带的持续收缩。 将化学试剂加入到陶瓷粉末和粘合剂的混合物中以操纵粘合剂的交联。 第一种方法是促进交联反应迅速完成。 第二种方法涉及在胶带浆料混合和流延过程中防止交联反应。 使用溶剂来加速粘合剂的交联,其中溶剂可以包括丙酮,乙酰丙酮,甲苯和乙醇中的一种或多种。 优选地,溶剂是丙酮和乙酰丙酮的组合。 可以加入多羟基化合物如甘油以加速粘合剂的交联反应。 胶带中的硼可以替代地作为粘合剂的交叉剂不起作用,在与粘合剂接触之前使硼与路易斯碱预反应。 优选的路易斯碱是有机胺,例如哌啶。

    • A method for forming a low temperature cofired ceramic package which is made using a multi-layered densified spherical powder formed via a sol-gel process. This densified powder is formed from layers of SiO.sub.2 reacted with trimethyl borate. The spherical powder has a preselected particle size and boron content sufficient to render the low temperature cofired ceramic package fully dense, even in the presence of a second phase filler ceramic, at a sintering temperature below 1000.degree. C. Binder material is added to the spherical powder and ceramic filler to form a plurality of tapes. A ceramic assembly is then formed by layering the plurality of tapes upon one another and firing the ceramic assembly at a temperature below 1025.degree. C. to form a fully dense cofired ceramic package. In order to form the multi-layered densified spherical powder, a silica core, which is formed using a sol-gel process, is reacted with trimethyl borate. An additional layer of silica is provided upon the reacted product which, in turn, is reacted with trimethyl borate. This process is continued until a spherical powder of desired size is formed.
    • 一种用于形成低温共烧陶瓷封装的方法,其使用通过溶胶 - 凝胶法形成的多层致密球形粉末制成。 该致密化粉末由与硼酸三甲酯反应的SiO 2层形成。 即使在第二相填料陶瓷的存在下,在低于1000℃的烧结温度下,球形粉末具有足以使低温共烧陶瓷封装完全致密的预选粒度和硼含量。将粘合剂材料加入到球形 粉末和陶瓷填料以形成多个带。 然后通过将多个带彼此层叠并在低于1025℃的温度下烧制陶瓷组件以形成完全致密的共烧陶瓷封装形成陶瓷组件。 为了形成多层致密球形粉末,使用溶胶 - 凝胶法形成的二氧化硅芯与硼酸三甲酯反应。 在反应产物上提供另外的二氧化硅层,其又与硼酸三甲酯反应。 继续该过程,直到形成所需尺寸的球形粉末。
