一、PCB邮票孔的设计
我们按照下图的封装尺寸来设计邮票孔，如下图所示：
1、邮票孔焊盘的制作
从上图看出来，焊盘的长为1mm、宽为0.9mm，钻孔半径为0.3mm；在设计pads焊盘栈中，填写这些数据，如下图所示：
钻孔偏移焊盘中心0.5mm。钻孔半径0.3mm，钻孔直径为0.6mm。
2、邮票孔焊盘的定位
各个焊盘的位置根据第一张图的位置定位，以形状中心为原点；焊盘放置完成如下图所示：

The PADS Layout user interface is designed for ease of use and efficiency. PADS Layout is designed to meet the needs of the power user, while keeping the beginner in mind. PADS Layout’s interface and interaction are similar to other Windows ™ applications. You can interact with PADS Layout using the keyboard, menus, toolbars, and shortcut menus.
To change the unit of measure to inches, mils (default setting), or metric units, click Options on the Tools menu. The Design Units settings are on the Global >General page of the Options dialog box. Leave the current setting of Mils.
During the many phases of the PCB process, you may want to select only specific objects. For example, during component placement you may want to limit selections to components and during interactive routing you may want to limit selections to connections or routes.
To accommodate this working preference, there is a Selection Filter. With theSelection Filter, you can specify which design objects are selectable. Items turnedoff in the list can't be selected.
You display attributes in the design as text labels. You can also add additionallabels to accommodate different size and location requirements for referencedesignators. The visibility and position of each label is managed within the Layout Editor.
You can predefine locations for attribute labels by adding placeholder labels in the PCB decal. The placeholders act as the defaults for new labels added or made visible in the Layout Editor.
Position the Name and Type labels in the decal where the text will not be obscured when visible.
1. Select button .
2. With nothing selected, right-click and click Select Text/Drafting.
3. Select each label and to move it press Ctrl+E.
4. Place them in the approximate location shown in the "Creating a PCB Decal"
