运行Datebase Check时发现有这样错误

在PCB画完后，我生成Gerber时老出问题，叫我运行DBdoctor,运行Datebase Check时发现有这样错误,不知该怎样解决。SMD_SOT23B，SMD_SOT23A，SMD_SOT23，VIA26这四个我的库文件中有，但我并没有放到PCB板上（有这样焊盘的元器件我已经把他删掉咯）；SMD162BY68，这个焊盘我的库文件中都没有，想问一下有那位大哥可知道这是什么问题.......

你是否可以尝试运行下Tools-->padstack-->Modify Design Padstack然后你在控制面板的 Options页点击Purge纽选All这样后应该就会解决问题吧

谢谢楼上的兄弟，真行啦！高手
