What is the relationship between the Protel99 component library and the footprint library? 10

Protel99 component libraries and package libraries can be independent or associated;

Protel99SE is an EDA design software applied to Windows9X 2000 NT operating system, using design library management mode, can be networked design, has strong data exchange capabilities and openness and 3D simulation function, is a 32-bit design software, can complete circuit schematic design, printed circuit board design and programmable logic device design, etc., can design 32 signal layers, 16 power supply - ground layer and 16 machining layers.

The packaging library refers to the size of the components in the schematic diagram and other information, because the PCB board is the packaging appearance of the components... It is not possible to generate a PCB without a footprint library. You can draw the encapsulation library yourself or add library files, just like the component library you drew earlier...

Hope it helps.

One of the SCH footprints in the package library is the component symbol, and the other is the footprint in the PCB, which directly corresponds to the physical object. If there are no SCH components in the PCB package or the pin numbers are inconsistent after calling into the network, you will find that some components are missing, or some components do not have network cables.

You can also add a library, or draw your own.

I often draw it myself. You draw in the project, draw it and save it, and you can use it.

I recommend drawing it by yourself!

1 First of all, it is necessary to have a complete schematic and a schematic of the device.

2 Click on the component in the schematic. Each component needs to be configured with a PCB footprint, as shown in the figure below.

3.Add a PCB file in the project directory, name the file, and leave the operation in the empty PCB file.

4 Click the Design button in the menu bar, and then click the Import button in the next drop-down menu to import the package.

5 In the dialog box that appears, click the ExecuteChanges button to import the package.

6 Package the imported PCB file and draw the PCB file as needed.

See a ddb file and save the library you made in it.

Open the PCB or the principle ** piece, click the Make (Project) Library under the menu Design, you can generate a library file containing all the components in the file, and save the component library name.

Select a component, click on the wreath in the picture, the symbol will appear, copy the symbol to the library you created for modification, and then save it.
