We will discuss Library architecture and required component models in the upcoming Chapter 5, but the essential models for components are parametric information, schematic symbol, PCB footprint, 3D Model, and Simulation models such as SPICE or IBIS. Here are a few: Essential LibrariesĮssential PCB libraries hold your component’s essential data. With the industry’s breakneck growth over the last decade, companies developed several types of PCB libraries to support various designs and changes. Because electronics is a constantly evolving field, there is very little that does not change in some way. Dynamic information changes while Static does not. Dynamic Informationīefore diving into the different types of PCB libraries, we must understand the Static and Dynamic information of a component. It just depends on which column of the balance sheet it falls on an asset or a loss. What does the PCB library Represent?Īt first glance, your library is just a collection of design data and information for PCB components. Most of the time, they are underappreciated, but they hold the most critical position on any PCB design team. I have always followed the rule: ALWAYS be excellent friends with your PCB librarian.
Importance of a PCB LibraryĮverything begins and ends with PCB design, and I fully believe that a PCB library is by far the most crucial piece. While some consider it small, we love having all that information readily available at our fingertips. Its most popular section is a list of PCB Resources where we place books, articles, video recordings, training materials, and anything else consider a good PCB resource. For example, our company’s ever-growing library has over 7,500-components. The most common part of a PCB library is the PCB design process components stored in a database. Library Definedįor PCB Designers, a library is not a building but rather an information or data collection structured for finding things quickly. However, what I find even more astounding is how all that material is kept organized to enable finding something very quickly. For anyone who has ever visited the Library of Congress, when you consider the tremendous amount of knowledge and materials within those walls, it is incredible. It is by far the largest library in the entire world. It is the most extensive rare book collection in North America. Now, it contains 32 million cataloged books and other print materials in 470 languages more than 61 million manuscripts. Once established, the Library of Congress originally held a total of 740 books and three maps. In April of 1800, when the seat of the government moved from Philadelphia to Washington, one of President Monroe’s first acts was allocating $5,000 to purchase books for Congress to use. When we think of a library, we first think of a building which holds materials of some kind.
