For this component, both of the two mounting hole pads have the same designator of '3'. When the Design » Update PCB command is used in the schematic editor to transfer design information to the PCB, the resulting synchronization will show the connection lines going to both pads in...
④ 双击“Single In-Line with no Mounting Hole.PcbLib”,出现如图2-48所示的“完成路径选择”对话框。若在图2-48中的“Name”(名称)框内填入SIP-P3/E10.4,则出现如图2-49所示的“填写封装方式名称”对话框。至此,已经把SIP-P3/E10.4封装方式与NPN建立了关联。单击“OK”按钮确定上述设置。回到“元器件属性...
Like all areas of design, getting a board into its enclosure is about give and take - adjust that mounting hole location, tweak this component position, then modify the display opening when the supplier flags the chosen display as end of life....

it is a very big mistake. It could lead to, well a horrible library. So, you should really look for details like this. Another case of misinterpreting data sheets is that most PCB manufacturers assume that the size of the drill hole you specify in your library is a finished hole size ...

Keepouts are perfect for designating non-routable circuit board areas like mechanically incompatible parts like mounting holes and the edges of a Circuit, high voltage regions, or electrically sensitive, especially exposed copper spots as in Test Points and Fiducials. After particular Keepout Limitation...
Hole chart. Allows you to add a table of used holes in the PCB Editor for subsequent drawing of the PCB; PCB types. Used to display scalable views of both the entire board (front or back) and individual areas with increased mounting density; ...
Your PCB layout should have all the required markings finished, as well as the mounting hole and fiducials shown here. Can you spot the silkscreen error in this image? Layers Check the layer stack and substrate heights meet the fabricator's specifications (or that the fabricator can meet your...
