PCB Calculator, now integrated with PCB Visualizer

We created a new PCB Calculator, the smartest tool we ever made.

There is more then just a new calculator page :

  • There are now 4 services, defined by their base materials. All (except PCB proto) combine both poolable and non-poolable options in a single menu with clear indications which is which.
  • Our Classification table has been updated to the new services and gives more freedom (space) for your design.
  • You can calculate your prices fully manually as before. But you can also use PCB Visualizer/PCB Configurator to analyse your data and fill out automatically many of the process parameters needed for pricing.
  • Smart menus guide you to optimum manufacturability and best prices, with clear explanations on-screen.
  • Prices are presented with a matrix of alternative quantities and deliveries. You can use the standard matrix or add your own requirements.
  • Standard delivery times for orders over 50 dm² have been reduced.

Farewell to our calculate and order page that was used over 250.000 times to place an order, and welcome to the new Eurocircuits PCB Calculator, smarter, easier and faster then before

new CadSoft EAGLE DRU files for EAGLE V6

New as from 18/09/2017.

EAGLE dru files have been adapted to our new service definition and PCB classification effective September 18, 2017 : Eurocircuits-EAGLE_dru_18-09-17.zip

We provide DRU files for the following Eurocircuits services :

New in EAGLE Version 6

In the new EAGLE Version 6 format, the EAGLE brd-file is saved in XML format. Also new in EAGLE version 6 is that the used Design Rules Settings (used DRU-file) are embedded and saved in the EAGLE board file (EAGLE brd-file).

In the previously released EAGLE design rules of Eurocircuits (eC-EAGLE-design-rules-24-06-2011.zip) the DRU file description contained quote-characters (“), which are not supported as such in the XML format.

Using these “old” eC-EAGLE-design-rules in EAGLE Version 6 will lead to errors when trying to load a Version 6 EAGLE brd-file which has been saved with the “old” eC-EAGLE-design-rules. The eC-EAGLE-design-rules have been updated to correct this problem:


When you downloaded the eC-EAGLE design rules earlier and you did not upgrade to version 6 yet, you do not need to install these new DRU files. When you upgraded to version 6 of EAGLE we advise to use these new design rule files.

Design Rules

During the design of a PCB and certainly at the end of the PCB design, it is imperative that you check your layout against some technology rules in order to be sure that you design a producible PCB layout.

The basic items to check in a design are related to the “copper image” of the PCB, these are:

  • the track widths
  • the isolation distance between different tracks and/or component/via pads
  • and the annular ring (or restring) on component/via pads.

Next to these basic items, other items that can be checked are for instance related to:

  • soldermask (eg Soldermaskpad oversize),
  • items related to the mechanical outline of the PCB (eg distance of copper to the PCB contour),etc…

All these different checks to be made we call the “Design Rules”.

“Design rules” can be specified in most of the CAD-PCB design software. In some they arevery basic, in other the possible settings are more extended.

For CadSoft EAGLE we have made different “Design Rule Settings” (DRU-files) which contain the specific minimum design rules for a specific service of Eurocircuits.
