## 一、Room Definition Violation
[Room Definition Violation] GeekIMU.PcbDoc Advanced PCB Room Definition: Between Room Sensor
主要解决方案是在DRC检查的时候删除掉不用的ROOM。
## 二、Minimum Solder Mask Sliver Constraint
这个问题主要描述的是两个焊盘之间阻焊层的最小间距。如果阻焊层的宽度过小PCB在生产的时候可能导致阻焊层制造失败。如下图所示
[Minimum Solder Mask Sliver Constraint Violation] GeekIMU.PcbDoc Advanced PCB Minimum Solder Mask Sliver Constraint: (4.842mil < 10mil)

解决方案在Design -> Rule -> Manufacturing中找到Minimum Solder Mask Sliver。设置4mil即可。
## 三、Silk To Solder Mask Clearance
这个地方设置的是丝印到阻焊层的最小距离。
<img src="E:\技术武器库\技术开发笔记\硬件开发笔记\Altium Designer\Image\Silk To Solder Mask Clearance.png" style="zoom: 67%;" />
解决方案在Design -> Rule -> Manufacturing中找到Silk To Solder Mask Clearance设置为0mil即可。
## 四、Hole Size Constrain
这个描述是最大孔径默认是100mil在生产制造的时候如果挖的孔太大可能机器的钻头无法钻出这么大的孔如果生产能力满足直接把规则设大即可。
解决方案在Design -> Rule -> Manufacturing中找到Hole设置为合适值即可。
## 五、Silk To Silk Clearance Constraint
描述的是丝印之间的最小间距这个问题不大大不了就是丝印混在一起了。有时候真不好处理可以设置为0mil。
