【摘要】 金属化膜厚是影响高温共烧陶瓷电性能的重要因素之一。研究了高温共烧陶瓷钨金属化浆料粒度、丝网规格、印刷工艺参数和烧结温度对膜厚的影响。结果表明通过控制浆料中的金属颗粒粒径,提高印刷丝网丝径和涂布的感光膜层厚度,优化印刷刮刀移动速度和烧结温度可获得设计需要的金属化厚膜层。更多还原

【Abstract】 Metallization film was an important factor of electricity capability on micro-electric ceramic packages. Effects of metallization paste, wire diameter, photo-sensitive film, screen printing speed and sintering temperature on metallization film were researched in this paper. We developed the metallization using controlled diameter of metallization paste’s powder, increased wire diameter of silk screen, thickness of photosensitive emulsion, optimized screen printing speed and sintering temperature.更多还原
