An embedded system is undoubtedly the most popular one of the most promising field of IT applications.Embedded systems

used in certain special equipment, these devices usually

hardware resources (such as CPU, memory, etc.) is very limited,

and the cost is very sensitive, sometimes to the real-time response requirements are higher.Especially the intelligent as consumer appliances, embedded more important.Like we

usually see mobile phone, PDA, electronic dictionary, visual

telephone, VCD/DVD/MP3 Player, digital camera (DC), digital

video camera (DV), U Disk, STB (Set Top Box), high-definition television (HDTV), game consoles, smart toys, switches, routers, nc equipment or instrumentation, automotive electronics, home appliances, medical equipment, aerospace equipment, control system and so on

PCB的各层定义及描述

为了方便与印制板厂家的技术沟通,提高对PCB的技术认知一致度,特在此将我司常用PCB的有关板层特性做简单说明,请爱好者参考此说明进行设计和制造。

PCB的各层定义及描述:

1、TOP LAYER(顶层布线层):设计为顶层铜箔走线。如为单面板则没有该层。

2、BOMTTOM LAYER(底层布线层):设计为底层铜箔走线。

3、TOP/BOTTOM SOLDER(顶层/底层阻焊绿油层):顶层/底层敷设阻焊绿油,以防止铜箔上锡,保持绝缘。在焊盘、过孔及本层非电气走线处阻焊绿油开窗。焊盘在设计中默认会开窗(OVERRIDE:0.1016mm),即焊盘露铜箔,外扩0.1016mm,波峰焊时会上锡。建议不做设计变动,以保证可焊性;过孔在设计中默认会开窗(OVERRIDE:0.1016mm),即过孔露铜箔,外扩0.1016mm,波峰焊时会上锡。如果设计为防止过孔上锡,不要露铜,则必须将过孔的附加属性SOLDER MASK(阻焊开窗)中的PENTING选项打勾选中,则关闭过孔开窗。另外本层也可单独进行非电气走线,则阻焊绿油相应开窗。如果是在铜箔走线上面,则用于增强走线过电流能力,焊接时加锡处理;如果是在非铜箔走线上面,一般设计用于做标识和特殊字符丝印,可省掉制作字符丝印层。

4、TOP/BOTTOM PASTE(顶层/底层锡膏层):该层一般用于贴片元件的SMT回流焊过程时上锡膏,和印制板厂家制板没有关系,导出GERBER时可删除,PCB设计时保持默认即可。

5、TOP/BOTTOM OVERLAY(顶层/底层丝印层):设计为各种丝印标识,如元件位号、字符、商标等。

6、MECHANICAL LAYERS(机械层):设计为PCB机械外形,默认LAYER1为外形层。其它LAYER2/3/4等可作为机械尺寸标注或者特殊用途,如某些板子需要制作导电碳油时可以使用LAYER2/3/4等,但是必须在同层标识清楚该层的用途。

7、KEEPOUT LAYER(禁止布线层):设计为禁止布线层,很多设计师也使用做PCB机械外形,如果PCB上同时有KEEPOUT和MECHANICAL LAYER1,则主要看这两层的外形完整度,一般以MECHANICAL LAYER1为准。建议设计时尽量使用MECHANICAL LAYER1作为外形层,如果使用KEEPOUT LAYER作为外形,则不要再使用MECHANICAL LAYER1,避免混淆!

8、MIDLAYERS(中间信号层):多用于多层板,我司设计很少使用。也可作为特殊用途层,但是必须在同层标识清楚该层的用途。

9、INTERNAL PLANES(内电层):用于多层板,我司设计没有使用。

10、MULTI LAYER(通孔层):通孔焊盘层。

11、DRILL GUIDE(钻孔定位层):焊盘及过孔的钻孔的中心定位坐标层。

12、DRILL DRAWING(钻孔描述层):焊盘及过孔的钻孔孔径尺寸描述层
