Pre-built CAD libraries are essential for PCB designers on tight deadlines. In order to reduce the burden on engineers to build parts, we have developed a source for free, accurate, pre-built component models that can be downloaded and added to a design in the Pulsonix toolset in just seconds. As a result, engineers utilizing our library of pre-built parts have reported saving hours of time, speeding up the design cycles by reducing the time spent on the mundane task of creating PCB libraries. We have partnered with Pulsonix to accelerate your design process by making verified pre-built schematic symbols, PCB footprints, and 3D STEP models accessible in your native CAD format. Search, analyze, and download free parts today.
Our expertise in libraries has allowed us to become a trusted partner for major IC manufacturers. Below are a few of the major IC manufacturers we have partnered with to provide a massive selection of parts for you to access.
Our desktop software allows you to author your own schematic symbols, PCB footprints, and 3D STEP models. Start with a template or from scratch and build parts to your company's particular specifications. Cross-probe between symbols and footprints to ensure accuracy, perform batch design rule checks, and export to over 20 different CAD formats.
