这是一个pcb铺铜后的报告。
这个报告不能被看作错误报告，只是报告了当前文件中有多少钻孔焊盘和不钻孔焊盘有多少不满足在options =〉thermals 中的设置。不满足不一定就是错误。
在 thermals 设置中，min spoke设置焊盘上最小的spoke 辐条数目，为1-4个。help中说：
Tip: If the pad intersects the boundary of a copper pour, it may not be possible to create all four spokes. A warning appears when thermals are created with fewer spokes than the minimum.
如果焊盘处于铺铜边框的边界，就有可能不能铺出全部4个spoke。当少于所设置的最少个数时就会有warning。如果设置最小是1，但是焊盘间距太小了，不足以放下spoke，这样spoke就是0，但是由于手动连线了，并不会存在连接性的问题。不过报告还是要报告的。这样就会出现所谓的error report。
另外还要注意，一般来说：Usually thermals are placed only on unrouted connections.热焊盘是放在没有走线的连接上。比如一个接地焊盘，可以在大面积铺地的时候自动铺上。但是如果你已经把这个焊盘连上地线了，那么热焊盘的设置就对他无效了。但是你也可以在这些铺了线的焊盘上设置热焊盘属性，这就是Enabling Routed Pad Thermals 选项的作用。
虽然help 是这么说的，但是我试了一下，选不选Enabling Routed Pad Thermals 得到的效果跟选上的效果是一样的。不知道是不是我理解的不对。
