给PCB连线的时候一些地线没有连接,想等到覆铜的时候都自动与铜相接,结果覆完铜之后,仍然看到地线呈现细白线,并没有与铜连,我是不是少了什么操作。

你有没有考虑到铜的面积相同的网名,你希望它连接到网络?

有的,我的铜都是GND,另外还在空一点的地方放了一些GND的过孔。 覆铜后却没有看见GND网络与覆铜相连。

需要重建覆铜,或者按下SHIFT+B https://easyeda.com/Doc/Tutorial/PCB.htm#Copper-Area

@dillon 请问下图所示焊盘是跟覆铜连接的吗?看上去好像是连接的,但是细小的飞线没有消失,这是为什么?是你们软件自身的原因吗? ![enter image description here][1] ![enter image description here][2] [1]: /editor/20160204/56b2c7a42a635.png [2]: /editor/20160204/56b2c7953d7fd.png

应该不是, 可能的原因 1, 可能是孤岛, 通过覆铜连接到GND的通路没有,这种情况就在焊盘的旁边加上GND 过孔。 2, 过孔离热了焊盘太近,被忽略了,这种情况可以连接一根比较短的导线到焊盘与过孔。 这两种情况的修改后都不用忘记按下SHIFT+B 重建网络。

There are two ways to connect pads when you use a copper area. Remember that the pads and copper area must all have the same net name. 1) You can connect pads by tracks and then add a copper area. 2) You can also connect pads only by the copper area. If you have pads that connected only by the copper area (as described in (2)) then, until you do **Rebuild Copper Area** (SHIFT+B) they will show fly lines (ratlines) to the nearest pads that are connected by tracks (even if those pads are also connected by the copper area). If you move the pads that are only connected by the copper area then the fly lines (ratlines) will appear again until you repeat **Rebuild Copper Area** (SHIFT+B). 有两种方法,当您使用的铜面积连接垫。 请记住,垫和铜的面积必须都具有相同的网络名称。 1)您可以通过连接轨道垫,然后添加一个铜面积。 2)您也可以只由面积敷铜垫。 如果你只有通过铜区的连接,然后,直到你**重建铜区**(SHIFT+ B)他们会表现出飞线(ratlines),只能就近垫(如(2)所述)垫由轨道连接(即使这些垫也由铜区域连接)。 如果移动仅由铜区域连接的片,然后飞线(ratlines)将再次直到你重复**重建铜区**(SHIFT+ B)出现。
