应用Protel99se设计电子时钟印制板电路

The Design of the PCB for Electronic Clock Using Protel99se

在印制板的设计与开发过程中,印制板上元器件的布局、元器件的走线都是印制板设计性能最重要的性能指标。应用AT89C51单片机开发的电子时钟电路印制板,电路功能清晰,电路具有测试实时温度以及记录时间以及日期的功能,具有一定的综合性。所以在文章中采用电子时钟印制板电路作为Protel99se的分析载体来分析印制板设计中的重要步骤以及关键技术。

During the design and development,the layout and routing of the components are the most important performance indexes for the design performance of the PCBs.The PCB of electronic clock circuit designed on AT89C51 has clear functions,can real-time measure temperature and record time and date,has certain comprehensiveness.So this paper adopts electronic clock PCB as the analysis carrier of Protel99se to analyze the important and key steps in the PCB design.
