In depth

A closer look at PCB123

PCB123 is an application designed to help engineers and other people interested in designing printed circuit boards (aka PCBs). It is a CAD utility in the true form not only due to its clean and well-structured interface but also because of the practical tools it provides you with.During setup, you can include or exclude additional components, namely a software development kit for writing plugins to integrate with PCB123, as well as a plugin with an application wizard template for creating PCB123 plugins in Visual Studio.

Create a board and customize PCB settings

You're welcomed by a user-friendly interface at startup whose appearance can be changed. With the help of a wizard, you can put together a new board by indicating the board name and an optional Netlist file. Multi-page Netlist files can be added, along with Protel, Tango, OrCAD and native PCB123 Netlist files.In the following wizard steps, you can define the board's width and height or use a template from the list, as well as set the number of layers and inner layer type. Additional board features focus on the soldermask and silscreen, PCB thickness, copper weight, and lead free.

Design CAD schematics using pro-grade functions

Using PCB123 you can design multi-page schematics complete with components the wiring between them and symbols. The work environment is well organized and provides you with quick access to all the tools you need, making the program efficient too. You can view the overall layout of the board or component you are designing, explore a 3D rendering, and display layers that hold schematics for each component.The PCB designer can automate a number of tasks. For example, when connecting the pins from different parts, it automatically generates the wires in between. You can also have the application place components on the board, minimizing the interconnection distance while keeping track of aesthetics.

Comprehensive and free PCB design software

While designing the PCB, it automatically creates a bill of materials that displays the part name, description, manufacturer, package, cost and quantity. Also, you can check the prices of the components as you progress with your work in order to monitor production costs.To further enhance the practicality of this CAD tool, you can check out the design rules while you’re creating the board. With the above to consider and much more to discover, PCB123 is clearly a sound choice when it comes to designing printed circuit boards.
