PCB-board design again after a long interval, many have forgotten, while groping after some of the odds and ends recorded for future fast start
PCB generally comprises four project file: xxx.SchDoc (PCB diagram), xxx.PcbDoc (PCB FIG package), xxx.SchLib (PCB schematic library), xxx.PcbLib (PCB package library)
General procedures: [drawn first PCB schematic library SchLib], then draw] [PcbLib PCB package library to associate the assembly package library schematic library
Then draw PCB schematic SchDoc [], to update it to the package FIG PcbDoc PCB [], Design-> update PCB Document, and finally a copper wiring can flutter.
Results preview
1, program structure.
2, schematic library
3, the package library
4, schematics
5, the package of FIG.
First, the integrated library production
Integrated Production Library (schematic library, PCB package library, PCB3D library), was added to the schematic components, introducing the PCB, PCB design and layout, 3D preview1, pins, etc. Before placing the TAB attribute set, press the space rotation
2, Designator is a flag pin, corresponding to the PCB pin package library, Tools-> principle model management database to associate them with the PCB package library
. 3, the chain line \ A \ B
Second, add 3D library
Three, PCB schematic drawing
Tools-> Annotate Sch .. -> Update Changes List -> Accepted Changes automatically add annotations, eliminating the error altium designer duplicate partFour, PCB board drawing
自动布线:Auto Route->All..检查规则:Tools->Design Rule Check..
小技巧
扑铜:
利于散热等
Place->Ploygen PourTop层和Buttom层都铺，注意铺铜的时候选择接地GND(在布线的时候地线不用连接)
注:第二种Hatched扑铜方式,线宽要选择10mil不然无法通过规则检查
原理图库修改后更新原理图 Tools->update Sch..
原理图修改后更新PCB封装设计 Design->update PCB Document
execute changes->validate changes
设置板子形状:
绘制边缘线条，shift键选择
Design->Board Shape->Define Form selected objects
板子变成灰色->右键->Filter->Clare Filter
设置电气边界:
切换到Keep-Out层，Place->Line厂家会根据这个形状生产。
电气边界用来限定布线和元件放置的范围，它是通过在禁止布线层（Keep Out Layer）绘制边界来实现的。禁止布线层是PCB工作空间中一个用来确定有效位置和布线区域的特殊工作层面，所有的信号层的目标对象和走线都被限制在电气边界之内。
Q键实现英制和米制单位转换
正反两面放置元器件:
法1、在拖动元器件的同时，按下L，该元器件就自动到底层去了。
法2、右击查看属性，修改Layer属性为Bottom Layer即可。
隐藏GND网络
扑铜时一般连接GND，那么在绘制PCB连线时隐藏GND连线会比较清爽
快捷键N-H-GND 点击GND焊盘就行了
注意一定要敷铜接地，不然整块板子全废了，血的教训~~~~
