石英晶體諧振器生產(chǎn)過(guò)程的統(tǒng)計(jì)分析技術(shù)及其應(yīng)用

摘要：作為大規(guī)模生產(chǎn)的電子元器件，石英晶體諧振器的生產(chǎn)過(guò)程不可避免的涉及到大量的統(tǒng)計(jì)分析。最基本的要求是統(tǒng)計(jì)生產(chǎn)過(guò)程的成品率，但我們往往可以結(jié)合數(shù)據(jù)的采集和分析同時(shí)來(lái)完成對(duì)生產(chǎn)過(guò)程的分析，達(dá)到對(duì)生產(chǎn)工藝進(jìn)行監(jiān)測(cè)和控制的目的。本文介紹了我們結(jié)合生產(chǎn)過(guò)程和特定器件，測(cè)定了石英晶體諧振器的制造特征參數(shù)，然后通過(guò)統(tǒng)計(jì)過(guò)程控制（Statistical Process Control, SPC）方法對(duì)每個(gè)參數(shù)作具體分析，最后確定了對(duì)產(chǎn)品質(zhì)量有顯著影響的因素。由于統(tǒng)計(jì)過(guò)程控制技術(shù)在電子元器件生產(chǎn)過(guò)程中有著廣泛應(yīng)用，在石英晶體諧振器生產(chǎn)行業(yè)也有著成功應(yīng)用的經(jīng)驗(yàn)，這一初步研究為我們改進(jìn)生產(chǎn)過(guò)程和產(chǎn)品設(shè)計(jì)提供了一個(gè)有效的努力方向。

Abstract: As electrical components of massive production, statistical analyses have been widely used in the manufacturing process. Although the essential objective is the yield analysis of production, the combination of data collection and analysis can also be an effective method for production process monitoring and control. In this paper, by measuring product parameters of quartz crystal resonators and analyzing these data with statistical process control (SPC) method, dominant factors on resonator quality are identified. Since the SPC method has wide applications in the electronic component manufacturing industry with successful outcomes, it is an important direction in the production improvement and the refinement of product design.
