死铜在哪里啊？？

我画了一个四层的板，中间两层中，其中一层是地，一层是电源，我把电源分切了好几块，为什么在电气检测中老是出现面的问题：

而在PCB中也看不到绿色的出错指示，请高人指点一下。

+ z; R5 k, G  V5 s可以设一个room区域规则，即在孔比较密集的地方画好room区域，把区域内的内层隔离环改小

挺不错的 谢谢~

你好 这个主题的问题你是怎么解决的 我也是遇到一样的问题 画的是六层 电源层和地层 你是怎么通过修改规则来去掉那些提示检测的 谢谢了~

重新生成一下内电层就可以了

呵呵 楼主估计也困惑好久吧 以前我也碰到过，找了好久才发现的。其实AD中的错误是有颜色标记的 就看眼力怎么样了

恩 不错

回复 SSDMA 的帖子

, r' K5 Z  u- ^: I8 C- d3 r+ U% D% n3 ]2 Y你说的对，后来在rule里改了就好了。哈哈

SSDMA

via太多，太密了。内电层的死铜，可以通过调整via的位置或其他方式去除。
表层铺铜的设置是没有用的

二楼的看法是对的。

覆铜的时候 不是有 除去死铜这个选项么？
