PCB123 Core Features
As a professional PCB design software, PCB123 not only provides basic functions, but also features such as schematic capture and real-time design rule checking, which can effectively improve design efficiency. Below, we list 7 core design features of PCB123.
- Component library integration with SnapEDA, SnapEDA has millions of verified components, when we add new components and build libraries, can simplify the process, you can quickly create a BOM, for freeing up our hands, saving the manual creation of components, reducing the workload.
- Schematic Capture: Using PCB123 to create and edit schematics will make the operation easier and support synchronized updates, reducing the risk of errors in schematic and layout views.
- Flexible routing: If we have specific custom functions, we can use PCB123 to manually route the wires, of course, it also provides automatic routing functions to better optimize the alignment design.
- 3D Rendering: With 3D rendering function, we can check the PCB boards before PCB production to see if there are any errors in alignment and layout, which is convenient to minimize the loss caused by the later production process.
- Rule checking: Real-time design rule checking, also known as DRC. the DRC function can mark the problem in real-time when there is an error in the design, checking whether the design is a bath conflict or violation, which is convenient to improve the accuracy of PCB design.
- Order Integration: As part of Sunstone's software, PCB123 integrates an “Order” button that allows users to seamlessly transition from design to manufacturing with Sunstone Circuits, while providing options for prototype and production levels. The following are some of the options available
- Manufacturing Options: PCB123 supports a wide range of board specifications, including different thicknesses, tighter tolerances, special copper thicknesses, and complex cutouts for sophisticated designs, ideal for advanced R&D and specific applications.

PCB123 Tips
The use of shortcut keys can save us a lot of time in operation. Below we will introduce a few very useful shortcut keys.
- [NAME1, NAME2, NAME3, ...] - Disjointed list. A list of names separated by commas will expand once for each name when placing consecutive objects. Example.
INTENS_[RED,GREEN,BLUE] expands for the next three items as:INTENS_RED, INTENS_GREEN, INTENS_BLUE.
- [#:#(:#)] - Numeric Range. two numbers separated by a colon (:) denote an inclusive sequential range. if a third number is supplied, then it is the increment, or it is the increment, or it is the increment that is not supplied, or it is the increment that is not supplied. If a third number is supplied, then it is the increment, or step, to be used when generating the sequence. Example.
ADDR[3:0] expands for the next 4 items as:ADDR3, ADDR2, ADDR1, ADDR0.
