A Study on Effect of Line Width, Composition and Firing Temperature on the Microstripline Properties

[摘要] The transmittance and reflectance of microstriplines of different widths, fabricatedby thick film and thin film technology are studied in the X and Ku band (8–18 GHz).The fritless thick film Ag pastes with different binder composition was formulated indigenouslyand screen-printed the microstriplines on alumina substrate. These microstriplineswere compared with the microstriplines made from ESL (USA) pastes and alsoCu thin film circuits. The effect of line width, composition and firing temperature on thethick film microstriplines was investigated. The transmittance of all the indigenouslyprepared Ag thick film paste compared well with microstriplines prepared with ESLpastes. All these thick film pastes gave good transmittance upto 18.0 GHz. The resultsindicate firing at 700℃ gives best films, and also 18 mil or 20-mil line width is moresuitable than conventional 25-mil line width if thick films are used for metallization upto18.0 GHz.
