热压工艺的改善对金属化薄膜电容器工作噪音的影响

Metallized Film Capacitor of Hot Pressing Process Improvement and Its Effect on Working Noise

本文对金属化薄膜电容器的热压工序选取了4种影响因素,每种因素选取3种不同的水平,进行正交试验。并通过试验对素子的厚度、容量和成品的工作噪音进行了测量。用试验结果作为评价对热压工序各因素的影响好坏。最终得出油压机的压力大小不仅对素子的厚度和容量起着主要的影响,而且也对成品的工作噪音起着最直接的影响。

The paper choose 4 different factor and 3 different level for each factor to do orthogonal test in order to improve metallized film capacitor hot pressing process.Then measured chip thickness,chip capacitance and capacitor working noise to evaluate process.At last,drawing conclusions that the pressure take the major influence to chip thickness,chip capacitance and capacitor working noise.
