1. Lichuang Mall EDA free library
In the process of designing circuits, we often encounter such problems: unable to quickly find the right component schematic package and PCB package (Footprint), usually the most basic approach is to find resources shared by others, or draw according to the size. . This approach is less efficient and affects the development progress of the project. This blog post will share three tips to help hardware friends quickly design component packaging.
1. Lichuang Mall EDA free library
Lichuang Mall is a one-stop electronic component procurement platform, mainly engaged in electronic component retail and small-batch procurement, with a stock of over 200,000 kinds.
Litron EDA is an efficient and free domestic circuit design tool that conforms to Chinese users' habits. The software is based on JavaScript and web pages. It not only has a client, but also directly uses a browser, etc. It has built-in over 1 million real-time update components. Help the majority of electronic designers to quickly realize their ideas from design to factory production.
For example, I need to find components: STM32F103RBT6 schematic package and PCB package.
Step 1: Find the component in the Lichuang Mall, you can see the components of different manufacturers and prices, as shown in the figure below:
Step 2: Click on the data sheet of the component that meets the requirements , you can view the data sheet, schematic diagram and PCB package of the component, as shown in the following figure:
Step 3: Click [Use Now] to enter Litron EDA, and view the schematic library and PCB library of components, as shown in the following figure:
Step 4: Click [File->Export] to download the schematic library and PCB library. Here I use AD (Altium Designer), so download it as an AD (Altium Designer) file format and you can use it directly, as shown in the figure below :
2、Altium Library Loader
Altium Library Loader is an artifact to download the Altium Designer package library. You can search and download the schematic library and PCB package library by entering the component model.
How to download Altium Library Loader? I have a little trick, go to Mouser Electronics , download the library to load the application software, as shown in the figure below:
After the download is complete, enter the file: Altium Library Loader , modify Altium Library Loader 1.8 Setup.ex_ to Altium Library Loader 1.8 Setup.exe, and then click to install the Altium Library Loader software (the installation process is relatively simple, omitted here), as follows The picture shows:
Open the Altium Designer software, and you can see the Altium Library Loader plug- in under the [File] path , as shown in the figure below:
After creating a schematic diagram at this time (necessary step!), click on the Altium Library Loader plug- in to find the required schematic library and PCB package library (after successful registration), the effect is as follows:
For example, I need to find components: LM1117 schematic package and PCB package, select the required components in the list, click ADD TO DESIGN , you can add them to Altium Designer (the network delay time is longer), as follows The picture shows:
At this time, the schematic package and PCB package of LM1117 are automatically added to Altium Designer. Usually, the Altium Library Loader plug-in downloads are all 3D libraries, and the effect is great as shown in the following figure:
3. Mouser ECAD model
Mouser Electronics was founded in 1964 and is headquartered in Mansfield, south of Dallas, Texas. It has offices in 21 countries and regions around the world, among which the Greater China region has service offices in Shanghai, Hong Kong and Taipei. Its e-commerce website sells 10 million products.
If the signal is poor and the network delay is large when using the Altium Library Loader plug-in , you can also download the ECAD model of the component from Mouser Electronics , and then use the Altium Library Loader plug-in to load it.
For example, I need to find components: LM1117 schematic package and PCB package.
Step 1: Find the component in Mouser Electronics, you can see the components of this type from different manufacturers and prices, as shown in the following figure:
Step 2: Click on the components that meet the requirements, as shown in the following figure:
You can see the open source schematic library, PCB library and 3D library files of Mouser Electronics, as shown below:
Step 3: Click Download to download the resource file (note: new users need to register an account), the downloaded file suffix is .epw format, can not be opened directly, you need to install the corresponding software, as shown below:
Open the Altium Library Loader plug- in in Altium Designer, and click OPEN ECAD MODEL (Note: You also need to create an empty schematic file first) to load the model.
Just click ADD TO DESIGN directly .
