按照标准化要求,新研制电子产品的图形均应符合中国标准出版社1989年出版的《电气制图及图形符号国家标准汇编》中制定的标准,我们还买进一批符合该标准的元件库(简称国标库).在印制板CAD(计算机辅助设计)过程中,普遍反映有许多不方便:(1)元件库不齐全,好多常用器件库中没有;(2)只能在低版本1.14的TANGO上调用,而在低版本1.14的TANGO上画电原理图操作繁杂,印制板布线布通率较低,只有60%～70%,特别是对初学者难度更大,效率很低.鉴于此种情况.船舶总公司扬州723所经过努力,将
In accordance with the standardization requirements, the newly developed graphics of electronic products should be consistent with the standards set forth in the “National Assembly of Electrical Drafting and Graphical Symbols” published by China National Standard Press in 1989. We also bought a batch of component libraries (referred to as National standard library.) Printed CAD (computer aided design) process, generally reflect a lot of inconvenience: (1) component library is not complete, not many common device library; (2) only in the low version 1.14 TANGO On the TANGO version 1.14 TANGO draw electrical schematics complicated operation, printed wiring board routing through rate is low, only 60% to 70%, especially for beginners more difficult and inefficient. In view of this Kind of situation. Yangzhou 723 ship headquarters through the efforts will be
