Abstract

The invention discloses an anti-battery effect isolation medium slurry for a thick film circuit. The medium slurry comprises the following components in mass percentages: 60%-75% of glass powder, 3%-12% of additives, and 1% of inorganic pigments ~5%, organic vehicle 20%~35%, among which the glass powder is composed of ZnO, CaO, Al 2 o 3 , SiO 2 , B 2 o 3 , TeO 2 Composition, the additives are composed of micron-sized anorthite, α-type nano-alumina, nano-ZrO 2 Composition, the micron grade anorthite ore is made by crushing anorthite ore, sieving through an 80-mesh sieve, and then roasting at 750-800°C for 1-3 hours, and then ball milling to a particle size of 1-2 μm after natural cooling. to make. The anti-battery effect isolation medium paste for thick film circuits of the present invention has the characteristics of excellent anti-battery effect, good printability, dense firing film layer, high breakdown voltage resistance, high insulation resistance and small dielectric constant.

Description

technical field [0001] The invention belongs to the technical field of slurry for thick-film circuits, and in particular relates to a battery-effect-resistant isolation medium slurry for thick-film circuits. Background technique [0002] With the development of microelectronic packaging technology, the scope of use of thick-film hybrid integrated circuits has gradually expanded, and high-integration, high-performance, and high-quality ceramic circuit boards can be prepared using thick-film technology. Thick-film circuit devices have begun to develop in the direction of miniaturization, integration, and high frequency, so that the product wiring density is higher, the volume is smaller, and it can be applied to a wider frequency range. The dielectric paste is required to have better resistance to battery effect, higher dielectric strength, lower dielectric loss, and meet the requirements for multi-layer wiring. [0003] At present, in high-reliability thick-film circuit prod...
