石英晶體諧振器生產過程的統(tǒng)計分析技術及其應用

摘要：作為大規(guī)模生產的電子元器件，石英晶體諧振器的生產過程不可避免的涉及到大量的統(tǒng)計分析。最基本的要求是統(tǒng)計生產過程的成品率，但我們往往可以結合數(shù)據(jù)的采集和分析同時來完成對生產過程的分析，達到對生產工藝進行監(jiān)測和控制的目的。本文介紹了我們結合生產過程和特定器件，測定了石英晶體諧振器的制造特征參數(shù)，然后通過統(tǒng)計過程控制（Statistical Process Control, SPC）方法對每個參數(shù)作具體分析，最后確定了對產品質量有顯著影響的因素。由于統(tǒng)計過程控制技術在電子元器件生產過程中有著廣泛應用，在石英晶體諧振器生產行業(yè)也有著成功應用的經驗，這一初步研究為我們改進生產過程和產品設計提供了一個有效的努力方向。

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.
