【摘要】：制備電子元件的關(guān)鍵和核心是電子漿料,其質(zhì)量的好壞直接關(guān)系到厚膜元件性能的優(yōu)劣。電阻漿料作為電子漿料的重要組成部分,制備成應用于厚膜電路中的電阻,被廣泛的應用在軍事、宇航、通訊及汽車等領(lǐng)域。二氧化釕(RuO2)電阻漿料是電阻漿料的重要組成部分。Ru02具有良好的催化活性,穩(wěn)定的化學性能等優(yōu)點,同時是類金屬性的高電導率金屬氧化物,在電化學催化、氯堿工業(yè)和集成電路等領(lǐng)域中得到廣泛應用。使用RuO2制備的電阻器,具有阻值范圍寬、噪聲小、抗還原能力強、耐受高功率的負荷、長期貯存穩(wěn)定性好等優(yōu)點,所以Ru02厚膜電阻漿料在片式電阻器和厚膜集成電路中占很大的比重。我國釕系漿料核心技術(shù)和生產(chǎn)能力達不到發(fā)達國家的水平,在一些領(lǐng)域所需要的電阻漿料依賴于進口,我國對RuO2電阻漿料進行了很多研究但仍然存在不同批次之間阻值不穩(wěn)定的問題。本文從Ru02的制備著手,使用化學沉淀法進行制備Ru02,分別在30℃,65℃,95℃下使用RuC13與NH4HC03,NaOH和四甲基碳酸氫銨(TMAHC)反應,之后將制得的粉體進行洗滌,過濾,烘干;使用水淬球磨的方法制備玻璃粉;使用水浴加熱的方法制得有機載體。將制備的RuO2、玻璃粉、有機載體按照一定的配比調(diào)制成為電阻漿料,之后印刷、烘干、燒結(jié)成電阻膜片,最終得出以下結(jié)論:在制備Ru02時,粉體粒度隨著反應溫度的增加而增大;在相同的反應溫度下,使用TMAHC溶液制備的RuO2粉體,相比于其他兩種溶液,分布更為均勻,團聚現(xiàn)象不明顯,同時根據(jù)測得的電阻片的阻值,在調(diào)制漿料時,更加適用于配制中低阻值的漿料;RuO2的晶化溫度在270-400℃之間,在850℃燒結(jié)之后,結(jié)晶水已完全消失轉(zhuǎn)化為金紅石型結(jié)構(gòu)。本文制備的硼硅酸鹽玻璃相,根據(jù)測得的電阻值、表面觀察和能譜分析,其高溫流動性和粘結(jié)性能更加適用于中高阻值漿料。
[Abstract]:The key and core of the preparation of electronic components is the electronic slurry, the quality of which is directly related to the performance of thick film components.As an important part of electronic slurry, resistor paste is widely used in military, aerospace, communication and automobile fields.Ru02 is an important component of resistive paste. Ru02 has good catalytic activity and stable chemical properties. Ru02 is also a kind of metalloid metal oxide with high conductivity in electrochemical catalysis.Chlor-alkali industry and integrated circuits and other fields have been widely used.The resistor prepared with RuO2 has the advantages of wide range of resistance, low noise, strong anti-reduction ability, high power load tolerance, good long-term storage stability, etc.Therefore, Ru02 thick film resistor paste accounts for a large proportion in chip resistors and thick film integrated circuits.The core technology and production capacity of ruthenium slurry in China is not up to the level of developed countries, and the resistive paste needed in some fields depends on imports.A lot of researches have been done on RuO2 resistor paste in China, but there is still the problem of instability of resistance value between different batches.In this paper, Ru02 was prepared by means of chemical precipitation method. Ru02 was prepared by chemical precipitation method. The Ru02 was prepared by the reaction of RuC13 with NH4HC03NaOH and tetramethyl ammonium bicarbonate at 30 鈩，
