[Software] using Pad Designer, PCB Editor
[Procedure]
Step one: Create labels pad
0603 pad dimensions are as follows:
Open pad designer
Make the following settings
Parameter Units Units page settings and precision Decimal Places, remaining default
page selection layers Single layer mode, and then set the BEGIN LAYER SOLDEMASK_TOP layer parameters respectively, SOLDEMASK_TOP ratio of each outer layer is about 0.1mm expansion BEGINLAYER
After the setup is complete, it will be saved
The second step: the establishment of C0603 Package
New File File -> New - "symbol
Allegro open software package to create a file, as follows, is added to the corresponding path, set the file name, file type and select Package symbol, and then click ok
Setting parameters
Setup-->Design parameter editor

Left X Left Y offset adjusted according to the specific size of the package
Setup-> the Grid
the Grid
0.1mm0.1mm
Placing pad
Layout- "PIN
Connect (placed via the electrical connection)
Mechanical- mechanical through hole
provided in the following manner related parameters
of the first column selection pad type, connect and Mechanical, connect conductive vias, Mechianical mechanical vias
Padstack selection file making pads
Qty number of x and y pads, spacing pitch as the pad center, order placement direction of pad
rotation angle of the rotation
pin # is a starting number pins
inc increments
Text block font size (pin number)
offset in the xy direction shift amount
0603 pad center spacing of 1.6-0.3 = 1.3mm
after setting up the package of FIG 0603 calculates the coordinates of the center of a pad according to
(-0.65 0)
input command in x -0.65 0 Enter
then right-click Done
Placing silkscreen
Package Geometry - "Silkscreen_Top silkscreen 0.15mm
using a trace command Line is drawn
and then provided as options to select the Add line command
is then packaged according to FIG positioning coordinates silkscreen
1mm than the land for the major left and right in the drawing file
in order to distinguish the capacitance and resistors, capacitors using 0603 arcuate design
using 3pt arc commands to draw
first set the parameters
and positioning of the two points
X -0.9 -0.5 Enter
iy. 1 the Enter
then use the mouse to the right position pulled arc
has been drawn on both sides of the arc after the command Add liner results, a straight line drawn down, it has been drawn as shown below
Mounting layer disposed
Package Geometry --》Assembly_Top 装配层 0.00mm
利用走线命令（和丝印层同样大小）
同方法四相同，只不过走线层数和线宽发生了改变
Placing boundary
Package Geometry --》Place__Bound_Top
Rectangle command using placed
after finished placing as shown below
Placing text

The same operation with silkscreen
Finished package as drawn C0603
