Three ways to package Altium Designer-painted components

http://blog.csdn.net/guanyasu/article/details/52557810

Here are three ways to share your Altium Designer-painted component package.

If there is any mistake, I hope you will correct me.

First, manual painting.

(1) Create a new PCB library.

The following is an example of STM8L151C8T6, which is its encapsulation information

Set the grid spacing (shortcut g), of course, can also be flexibly set in the design, introduce a shortcut key ctrl+q can be achieved between the mil and MM unit switching.

Placing Pads (accelerator pp)

Press the TAB key to set the pad, ctrl+q achieve the mil and mm units of the switch, everyone according to their own habits. There is a need to pay special attention, if you want to manually weld, such as the above image of the package information on the pad length L can not be completely in accordance with the design of its packaging manual, generally than the manual of large 1-1.5mm. This can be done by hand soldering.

Set it up so you can start drawing. Finally, the silk screen painting, painting the perfect words, some of the mechanical layer is also painted.

After painting, be sure to use ctrl+m to accurately measure the various dimensions of the package you have painted.

Ii. Use of Component Wizard

The last method is often very slow to draw, and it has to be calculated for a long time. Let's introduce the second method, using component Wizard.

Tool-component Wizard

Press Next>

You can choose to paint many kinds of packages above, but without the LQFP package, we choose a quad package for demonstration.

Next>

If you want to manually weld, still need to pay attention to the problem of the length of the pad, plus 1-1.5mm.

Next>

Sets the first pad shape and other pad shapes.

Next>

Sets the line width of the screen print layer.

Next>

This looks at the parameters on the data sheet for calculation settings

Next>

Select the position of the first pin

Next>

Select Pin Count

Next>

Give the package a name

Next>

Finish

Basically this is the painting, and finally must be ctrl+m to measure and adjust.

Iii. use of IPC compliant footprint Wizard

The second method is also part of the calculation, and then to introduce a "lazy method", in line with the IPC packaging standards can use the IPC compliant footprint Wizard

TOOLS-IPC compliant Footprint Wizard

Next>

Choose the package form, with a clear view of the preview

Next>

Exactly as set out in the data sheet

Next>

Next>

This is to set the hot pad parameters, for some of the larger heat of the chip, the bottom has a heat dissipation metal hot plate, here set its parameters, no need to set up.

Next>

This is the software that automatically generates some distance parameters, using its default values. Of course, you can change it yourself.

Next>

Select the density parameter of the board

Next>

Calculates the tolerance of the component, which can be used as a default value or can be changed by itself

Next>

Some error parameters can be used directly with the default value

Next>

or set the parameters, you can also set the pad shape.

Next>

To set the line width of the screen printing layer
