两种蚀刻法制作埋嵌电容PCB的对比研究

摘要

Etching methods is extensive studied and used in producing embedded capacitor PCB. Two kinds of etching methods as the double-sided etching with one lamination process and the single-sided etching with two lamination process were studied in this paper. The key points in processing embedded capacitor PCB were also pointed out. The capacitance measuring and the reflow test were adopted for comparative analysis in capacitance value accuracy and heat-resistant properties of the different methods. And the advantages and disadvantages of these two methods were made clear.%蚀刻法是埋嵌电容技术中研究与应用较多的方法。文章研究了双面蚀刻一次层压与单面蚀刻两次层压这两种工艺方法，并指出了两种方法加工埋嵌电容PCB工艺过程的关键点。通过电容值测量及回流焊测试，对比分析了不同工艺方法对埋嵌电容PCB的容值精确度及耐热性能的影响，明确了这两种工艺方法的优缺点。
