The Panel Editor is part of the PCB Visualizer and allows you to view, create and modify panel layouts for your PCB’s whether it is a step & repeat of a single PCB layout or the nesting of multiple PCB layouts.

There are tools for adding fiducials, tooling holes, text, spacers, rotating the PCB, frame and border elements.

Using the Panel Editor allows you to check the panel on-screen and order with confidence.

Please see our Panel Guidelines for more information about creating panels.


Most Panel Editor options can be used before you upload your data. For this, PCB Visualizer uses a dummy PCBs of the size you enter.

There are three panel options.

  • eC Panel by Eurocircuits
  • Customer Panel by Eurocircuits
  • Customer Panel by Customer

For more information on these panel formats please see our Panel Guideline.

To select PCB’s delivered in a panel format select panel next to Delivery format. If you selecting eC-panel by Eurocircuits or Custom Panel by Eurocircuits this will automatically open the Panel menu.

PCB Configurator Panel Section

Selecting the Delivery format as panel opens the Panel section – enter the values for the panel and a price will automatically  displayed.

eC-panel by Eurocircuits

Specify the repeats you want in X and Y. Select the panel border, and the PCB spacing from the pull-down boxes.

All eC-panels are compatible with our eC-registration system and have all the necessary tooling holes to use with our eC-stencil-mate or eC-stencil-fix (eC-Stencil required).

As they also have our standard pattern tooling holes and fiducials and are 100% suitable for use with other registration systems.

See our Panel Guidelines – eC-Panel by Eurocircuits.

Click Panel editor to see the panel with the dummy PCB’s.

Customer panel by Eurocircuits

Click the Panel editor wizard and proceed as below to specify the step and repeat, border and separation distance required. Ignore the red warning message about the 0,0 panel size – this will be changed by the Panel editor. PCB Visualizer will display the default board size, so for an accurate price enter the correct circuit size, make any other size changes required and click Apply.

TIP – Don’t put in the border elements at this stage as they will be lost when you upload the real board data.

Customer panel by customer

Use this panel option if you have already prepared data files with the complete panelisation for a special layout or for a multi-panel (panel with several different designs).

Your layout should meet our panelisation requirements (see our Panel Guideline) for panel border and distance between the circuits.

This option will not open Panel Editor as the files will be display as you have created them in PCB Visualizer.

TIP – All delivery panels require a border to hold them together during transport and handling. If you have not included a border or want to put additional features into the border, select Custom panel by Eurocircuits and specify a 1-up panel using the Panel Editor.


Step 1. Load the job into PCB Visualizer

Sign-In to your Eurocircuits customer account and upload your data, click “Add to basket” and your data will be analysed. Alternatively, select the job from your customer account shopping basket.

Step 2. View eC-panel by Eurocircuits.

If you have already specified the step and repeat, border size, PCB separation method and distance, click the Panel editor to see the panelised circuit.

NOTE – The router path is shown as a hatched area. Our engineers will place rout tabs in this area to ensure a stable panel.

TIP – If there are areas in which you do not want rout tabs to appear due to sensitive components etc., specify them in a mechanical drawing.

You can now change:

  • Repeat in X and/or Y
  • PCB separation method
  • Panel border
  • PCB spacing
  • For any other changes, click “Advanced panel options”.

Click “Apply” at the bottom of the screen and the price in PCB Configurator will open and the price will be automatically updated.

  • For hints and tips on designing stable panels including panelising round circuits and handling overhanging and heavy components please see our Panel Guideline.
  • If you are using an external assembly company and they supply a detailed dimensioned drawing of their requirements, you may find it easier to use the Launch inquiry route to get a price. Upload your single circuit data, the drawing and your step and repeat instructions (as a README file) and our engineers will lay out the panel and give you a price. This may take up to 1 working day.


Panel and Boarder Properties

Change the panel and PCB properties in this menu.

Use this menu to change:

  • Panel size
  • Panel border
  • Board separation method
  • Board separation distance

Alternatively, add eC-registration compatible holes if you want to use a solder-paste stencil with our eC-stencil-mate or eC-stencil-fix.

TIP – If the board size is incorrect, PCB Visualizer will show a dummy panel. Correct the size in the menu (“Board size”).


Click within the existing stepped circuits to select the block. This opens the “Stepped PCB properties” menu. You can now change the repeat and the rotation of the PCB.


Change the step & repeat values


  • Deselect the Automatic X and Automatic Y boxes in the “Panel and board properties” menu.

MOVIE: Use the panel editor to create your own custom panel


PCB Visualizer has been developed as a Gerber file analyser to run Design Rule (DRC) and increasingly Design for Manufacturability (DFM) checks on single circuits.

There is at present no functionality to allow you to import and place interactively separate circuits into one delivery panel.

If you want to put several different circuits on one delivery panel, you have three options:

Prepare a single Gerber file for each layer including the circuits you require in the positions where you want them in the panel. Make sure that you provide a suitable border and distance between circuits.

  • You can use PCB Visualizer to analyse the panel as though it is a single circuit. If you need to add a border or border features, load the job as a 1 x 1 Customer panel by Eurocircuits.
  • To ensure optimum manufacturability we have rules for the maximum size and copper balance for panels with multiple different circuits.
  • Use the Launch inquiry route. Upload a single .zip file including separate .zip files for each circuits and an exact drawing how you want them panelised. Our engineers will check the data files and build the panel for you. We will send you a quotation and you will be able to see the finished panel in PCB Visualizer.
  • Place your order and upload a single .zip file including separate .zip files for each circuits and an exact drawing how you want them panelised. Skip PCB Visualizer. If you want to check the panel before it goes into production click the box “Request pre-production approval” in the Running menu.
