What keeps us busy at Eurocircuits, projects we are working at, new idea's, background information and a platform where you can participate, give your opinion and guide us to what is important for you as an electronics developer

In principle any PCB order can be pooled with other orders. Basically there is only one condition that needs to be met: We have enough similar orders to join together into one larger production order. However, it does not simply end there for us, we also need to ensure that the technology of the orders is compatible and their ordered quantities match.

For many years now our calculator has dealt with the technological aspects of order pooling. Our PCB Configurator will flag up any restriction with the technology requested by the customer which is making pooling unpractical. If a board cannot be pooled, the cost of board production increases significantly because it has to be manufactured separately on its own production panel.

We have now equipped our PCB Configurator with a comparable logic for order size mismatches. The larger the order, the less practical the order pooling will be. Based on the size of your PCB/customer panel we calculate how many production panels will be needed to produce the order. If for our STANDARD pool service, the number of production panels needed to make the order will be larger than 25, then order pooling is no longer viable. In that case we calculate the order as non-pooling. The PCB/customer panel size will influence the production panel efficiency factor which will be the major cost driver for the board price.

In case PCB configurator finds a non-pooling condition, it will flag it up under remarks explaining the reason for it and will highlight coins next to the order details that are the cause of this condition. At the same time under remarks we specify the “production panel efficiency” as a %. This makes it possible to adapt the size of your PCB/customer panel to a more efficient size driving the “production panel efficiency” up and thus the price per piece down or specially for small orders to increase the quantity to better fill the production panel at the same total order price.


Two examples will explain better what is involved.


Non-poolable technological option and production panel fill

A 4-layer board, 65x55mm in reverse build making it non-pooling and this as a 2 piece’ prototype order.

Non-pooling means we have to make one production panel for this order and cannot fill the empty space with other orders. The production panel efficiency is 4%.

More boards will fit on the panel. You may increase the number of boards thus increasing the production panel efficiency. Increasing the quantity to 40 will upgrade the production panel efficiency to 81% and will hardly move the total price.


Non-poolable quantity and inefficient customer panel

A double sided board 65x55mm in customer panel in BINDI pool +/- 1.600 pieces needed.

Using a more or less square customer panel of 4x4 has a production panel efficiency factor of 59% and will result into a price per piece of 16.23€/16 = 1.014€.

Simply changing the customer panel to 5x3 will solve all remarks and results into a price per piece of 10.64€/15 = 0.709€ or 30% less by simply permitting us to utilise the production panel space more efficiently.


These two examples explain two classic cases of optimizing non-poolable orders by either filling the one production panel in case of a small prototype order or optimizing the production panel efficiency by opting for the ideal customer panel size. In both cases we have a WIN-WIN situation between our customers and Eurocircuits by keeping the non-usable area to a minimum. Our PCB Configurator helps you doing that.


More background info:

Non-poolable quantities counted in more than “X” production panels per service are:

  • STANDARD pool – 25 production panels
  • BINDI pool – 25 production panels
  • IMS pool – 25 production panels
  • RF pool – 10 production panels
  • SEMI-FLEX pool – 5 production panels
  • NAKED proto – 5 production panels

Production panel size are:

  • 0L, 1L, 2Layer - 24”X18” leaving a net area of 581mmX428mm
  • Multi layers – 21”X18” leaving a net area of 501X428mm



All size and production panel efficiency calculations in PCB Configurator are made using the rectangular contour of the PCB/customer panel.

For all complex shapes or very complex panelisations, we advise our customers to make use of the “Launch Inquiry” option in the service selection page.


Order pooling is Eurocircuits’ mission.

Eurocircuits doesn’t take a summer break since your project deadlines don’t either. 

Our full range of PCB manufacturing services is available throughout the year. We have no summer shutdown; we only close the plant for Christmas and New Year. 

As a board designer you need to be confident that your PCB supplier can offer fast and reliable deliveries whenever you need them. To achieve this needs experienced and specialist capacity planning. With no summer shut-down we must have spare capacity to accommodate machine downtime for planned maintenance, as well as to meet demand growth and demand spikes. We have generated this extra capacity through ongoing investments in new plant and equipment. Capacity planning has allowed us to handle demand growth (orders up this year already 11% on the same period in 2015), as well as routine maintenance, without weakening our on-time delivery rate. 

And if something goes wrong? Where possible we have duplicated processes and machinery, and we have two plants in Europe geared specifically to PCB prototype production, both using the same business model we have refined over the past 25 years

Our production staff are committed to providing a continuous service with reliable deliveries all year round. Our support engineers are equally committed to sharing our knowledge of PCB fabrication with the design community. They make sure that there are engineers on hand every day to answer your chat requests. 

To see one of our factories in action, go to the video of the Eger, Hungary factory or in more detail How to make a PCB, also filmed in Eger. See another reason why, when you place your order, you can be confident that you will get the right board on the right day.

One problem designers have always faced is the ability to program various microcontrollers especially when each runs and requires different software and interfaces to program them, meaning that you need to have various adaptors and software knowledge for each of them …..

Until now, a programming adapter was just an interface between the microcontroller and the matching flash- or debug software. The USBprog already contains these softwares which can be accessed via a network and a web service using a browser. A first time user will gain easy access to program or debug the microcontroller using any operating system and any computing device.


Buy it from the Eurocircuits online shop.





The USBprog 5.0 OpenOCD is a programming- and debug adapter that can be managed from a Windows, Mac or Linux PC without the need to install additional software. In the simplest case you can operate it via a web browser. If the programmer should be triggered by a batch- or make file, there is a simple command tool available.



-ARM JTAG / SWD debugger and programmer
-AVR ISP programmer for flashing standard processors
-Level converter (Adjustable 1.8V, 3.3V and 5.0V)
-Browser interface for easy operation
-Manual for integration into the Atmel AVR Studio 6
-Web service interface for a command line tool
-Connection Via USB network interface (RNDIS)
-Firmware archive to import a software easy in to production repeatedly


The USBprog 5.0 combines many programmers in a single device. Operated via a browser, there is no need for configuring the device. The USBprog 5.0 works with Windows 7 and 8, MacOS and Linux.

To start: plugin the device, setup a network connection and connect via browser Programming and debugging has never been so easy.

The 23rd of May 2016 we celebrated the 25th anniversary of our company.

The journey started 25 years ago in a dark pub in the center of Mechelen, Belgium, where Luc and Dirk shared the dream to start their own company. The Belgian beer gave them the courage to do so.

In 1991 Luc visited Hungary with nothing more than this courage and was lucky to meet the right people at the right time with the right spirit. We want to thank all these people that contributed to the successful company we are today.

We do have something to celebrate. In 25 years we built a company that generates a yearly turnover of more than 20 million euro. More than 300 families in Europe and India depend on our operation for their daily income. More than 10.000 customers place orders with us every year, we target to process 100.000 orders this year. And all this in an industry in crisis, where the majority of the companies from 25 years ago do not exist anymore.

This proves the success of our strategy, the quality of our teams and the flexibility of our organisation.

We are ready to continue our journey and explore further opportunities in the future.



To remember this 25th anniversary milestone, we have cut our name in the stone of a CNC drilling machine that served us 25 years long, and was only recently taken out of production.

At the same time of celebrating our 25th aniversary we could officialy op our new building.

For some years we felt the need to increase the production surface in Hungary. Finally in 2013 the decision was made and  started the project. After planning, organizing the location and all the permissions, we contracted with Aktual Bau, who also built our existing building in 2004. The construction started in july, 2015 and was finished last month.

The building is a part of our 4M€ investment project 2015-2016. With it, we created extra space to expand and serve our customers with a broader pallet of services.




We had the pleasure to share these happy moments with our European staff who joined us in Eger Hungary from the 20th till the 22nd of May.

Some impressions are bundled in this short movie.

The benefits of the Gerber X2 format

Perfectly understanding customer data and not losing any PCB design information in data transfer, are key issues to seemlessly produce and deliver quick turn around PCB prototypes.

In our BLOG section we already explained the history of the Gerber Format. We have written a white paper on which actions we need to perform once we have received your data to check them and make them production ready. And we have informed you that UCAMCO is no longer supporting the old Gerber RS-274D format.

Gerber X2 is todays' standard. Why should you use it?

X2 adds intelligence to the Gerber format by its use of attributes. When PCB Vislualizer processes your new job, attributes allow the software to put the layers directly in the correct position in the stack-up. Other attributes identify the via pads, the SMD pads and so on. This avoids manual interaction and offers extra info for DRC and DFM checks. UCAMCO's Gerber X2 intro movie offers a sneak preview in the CAM-engineers environment where he uses a UCAM system reading in X2 and experiencing its benefits.

CAD systems - KiCAD, Pulsonix, Easy-PC, DipTrace and Altium - can all generate Gerber X2 files. UCAMCO cooperated with the CAD and other software vendors to validate their X2 output. We like the efficiency of X2, please use it as It will improve data transfer from you to us in a safe and practical way.
