What is Protel99se? How to draw the package of protel99se?

Protel99se is a popular PCB design tool that occupies a prominent position in the electronic design industry with its excellent functions and intuitive user interface. Protel99se enables designers to accurately map the physical properties of electronic components onto circuit boards, moving from concept to reality. Through this process, designers can ensure that circuit designs are not only theoretically feasible, but also work efficiently in practical applications.

Protel 99SE package drawing steps

1. Start the software and create a new project: easily start the Rust journey Want to embark on the road of Rust development? Then starting the software and building the new project is a crucial first step. This article will provide you with a step-by-step guide to quickly get started with Rust development and easily build your first Rust project. Next, we will explain the following in detail: Install and start the Rust tool chain Create a new Rust project Write and run your first Rust program Use Rust’s built-in tools to improve development efficiency This guide is carefully written by PHP editor Xigua. It is very suitable for Rust beginners, allowing you to easily get started and start writing your own Rust programs.

   • Start Protel 99SE software.
   • Create a new project.

2. Open the package library file

   • Enter the Documents folder.
   • Right click on the empty area.
   • In the pop-up dialog box, select "PCB Library Document".
   • Double-click to open a *.LIB file.

     

     2. In the menu bar of the software interface, select the "New Component" option under "Tools", which will start the PCB component packaging wizard. The user can choose to follow the wizard, or click "Cancel" to not use the wizard and directly create a new component in the "Components" directory and rename it.

     

     1. Set the drawing origin and grid size according to personal design habits. This is the basic setting step before encapsulation drawing.
3. Refer to the component specifications to set the pin diameter and hole size. The pad diameter is usually 0.5-0.8 mm larger than the hole diameter, and the pin pitch is typically set between 1.15-1.35 mm. Draw borders for pads and components based on specific design requirements.
4. Draw the frame of the component according to the size requirements in the specification sheet to ensure that the appearance of the package strictly complies with the design specifications.
5. Protel 99SE provides two main ways to create packages: manual drawing and using wizards. The manual method allows users to use drawing tools to freely draw packages according to design requirements; the wizard method automatically generates packages through preset design rules.
6. Through the PCB component library manager, users can easily browse, add, delete, place and edit pin pads and other operations of components, and efficiently complete the creation and maintenance of package libraries.

   

   Through these steps, users can systematically master the creation and management of the Protel99SE package library, providing a solid foundation for electronic design projects.
