Until PCB123 V3, a netlist was the traditional data transport from a schematic program to a layout program. I understand process lead-time does not begin until I have approved the converted files. A component, or part, is usually specified in a netlist as a name/type pair. Inside this folder, there is a folder named Custom, which is where any libraries that you create will be stored. The pan distance using these menu commands or their keyboard accelerators is the width or height of the window minus a comfortable overlap figure. Conduct market research and work more on the business front 6. Now you are ready to explore the design space. It will also allow you to plan ahead and create your design within these capabilities so that you can be sure Sunstone can produce your PCB. 2022 Sunstone Circuits. All Rights Reserved. If they both attempt to load in a component with the same name, then the component in the template wins and will be used in place of the one in the netlist. The button labeled G is not actually a zoom command at all. Identify the electronic components that your design will use and either map them to footprints from our supplied libraries or create any custom footprints as needed. A maximum information model is created in both the physical (layout) and logical (schematic) views when objects are created from inside the schematic and not from inside the layout. PCB123 handles 2, 4, and 6-layer boards as a standard process. Ground and power layers are clearly marked to indicate proper polarity. The next task will be to perform a Design Rule Check (DRC) and address any problems that it may have uncovered. Download Templates (EC design rules) for Altium designer users. If changes are made to the schematic then a new netlist must be generated that reflects the changes. You can select multiple designs to open by holding down the Shift or Ctrl key while clicking on files.

The Parts In Use area contains a list of all of the parts that have been added to your project. Like the tooltip, the context menu (shown left) is translucent to prevent objects underneath the menu from being obscured. A custom-made ceramic housing machined from a low-loss dielectric holds an array of 157 Pogo-pins, each with 2.9 mm-length in fixed positions. The pan behavior is a byproduct of how Zoom In and Out work with the wheel. These regions are collectively known as copper pour. Your screen should look similar to the image below. I am thinking about using Sunstone Circuits. Perform a continuous selection by sweeping out a rectangular area that involves pressing the left mouse button down on a spot that contains no objects, dragging until the rectangle encompasses the objects you wish to select, and then releasing the left mouse button. Depending on the board complexity and the time of day you placed the order, you will receive your boards anywhere from 2-5 business days later. For instance, when you are routing a trace, you will instantly get a visual clue if you create a short to another object or if you violate minimum spacing requirements. For the first time, PCB123 eliminates the netlist as a data transport as long as the schematic was designed in, or converted to a PCB123 schematic.
