NAKED proto – your questions answered

Why do I have to use PCB Visualizer before I order?

Using PCB Visualizer cuts out data issues. That keeps NAKED pool prices down – and your deliveries on time. Use PCB Checker to catch DRC errors and Build Editor for unambiguous layer assignments, especially for single-sided boards.

Can I use 0.15 mm tracks?

Yes: we’ve updated the service spec. Live production has shown us that 0.15 mm tracks are safe. But minimum isolation must stay at 0.175 mm to avoid the risk of solder bridges during hot-air levelling.

Why is the surface finish leadfree hot-air levelling (HAL)?

Leadfree hot-air levelling is particularly well suited to hand-soldering prototypes and small batches. It is also our most popular finish.

SEMI-flex pool news

Our first major SEMI-FLEX project is ready to go. More than 2.000 SEMI-FLEX PCBs have been completed for the e-brace hand-shake recorder to be assembled live at the E&A Show in Holland. The wearable gadget is based on a SEMI-FLEX PCB with 3 rigid and 2 flexed areas.

Virtec – an eC-test-mate user reports

VIRTEC S.R.L., Hurlingham – Buenos Aires, Argentina, customer of eC-test-mate

VIRTEC S.R.L., located in Hurlingham, Argentina, is a committed user of the eC-test-mate. Its CTO, Mr Juan Andres Mondolo, chose the eC-test-mate (and its accompanying software eC-my-test) to cover all testing needs within the company. Already, Virtec has realized testing solutions for two products with the eC-test-mate, and more are coming up this year.

Virtec provides products for data collection in vehicles and transport applications as well as for environmental monitoring, e.g. for agricultural purposes. With over 300,000 systems sold, Virtec offers solutions for fleet monitoring and telemetry in several South American countries. In order to withstand harsh working conditions with high reliability, the products must be robust and the electronics must fulfill high requirements regarding durability and long term functionality.

Why choose eC-test-mate?

Virtec was one of the first companies to purchase an eC-test-mate, which was introduced at the Electronica 2014 trade fair in Munich. What were the main reasons for Virtec to choose the eC-test-mate?

As Mr Mondolo puts it: “We use the eC-my-test software for the development and execution of our product testing, and we ask our contract manufacturers to implement it as well, using our test scripts. This offers the possibility of a high level of production standardization and guaranteed quality at very low costs. Also, our trust in Eurocircuits as a supplier played a significant role” Virtec is an innovative company that releases six to eight new products every year. These include completely new products as well as variations of existing solutions.

“Flexible application is therefore a key requirement for any test equipment, and with the eC-test-mate we have found just that. We only have to incorporate a standard footprint in each PCB design, assign the 21 test points and write the test commands for every test pin. That is why we use the eC-test-mate in the development, as well as in the production phase of the PCB”.

Before eC-test-mate….

Mr Mondolo explains that the eC-test-mate means a breakthrough for Virtec’s test strategy:

“Using this functional automated test system enables the company to test its PCBs thoroughly and in a shorter time period than before. A complete test of one of our newest product with the eC-test-mate, including programming of the firmware, takes around six minutes and now our contractors are able to process proximally 1600 tested PCBs per month. Additionally, providing the contract manufacturer with a user friendly and ready-to-use test solution helps to ensure that every PCB is tested to our specific requirements.”


As a result of this standardization of our testing process, it now becomes interesting to be able to store the test results. With eC-test-mate it is possible to store the results in a dedicated database via TCP connection. It also allows the programming of an ST microcontroller as part of the test process.

Virtec mainly uses the following eC-test-mate functions: Analog and digital in- and outputs, power supplies, UART, RS-485 and CAN. These functions are all included in either test head 1 or test head 2.

More possibilities in a very short learning period

According to Mr Mondolo, it took him only a few hours of ‘getting to know the program’ and working through a complete test development to master eC-my-test, and to be able to execute the first tests. The process was significantly easier than developing tests using standard programming languages such as C, C++ and Visual Basic.

“Overall the step from simple (manual) testing over connections and optical inspection to the implementation of the eC-test-mate was quite easy, and as we move forward we continue to see more advantages in working with the eC-test-mate system. We don’t need separate test fixtures or custom made beds of nails for our products, and we don’t have to purchase test software from yet another supplier. With one investment we now completely control the test development and test execution of all of our products and can therefore offer highly reliable and cost-effective solutions to our customers.”

Eurocircuits supports innovation – Parcelhome smart letterbox


Concerns about delivery and complex returns from home are key reasons for consumers to avoid online purchases. Now, has developed an all-new way for Belgian parcel delivery services to solve both problems at once. With its smart letterbox, this start-up has developed a package delivery system at home that both couriers and consumers can open using a smartphone app.

Carriers DHL Parcel, GLS and DPD see an opportunity to improve their service to consumers. Both carriers and consumers lose when no one is home to receive a package. At present, 15% of packages cannot be delivered on the first attempt, and in some residential areas up to 50% of deliveries fail. This trial in the Mechelen area is the first project in which multiple carriers cooperate to improve home delivery rates. The smartbox is the result of 18 months of research and development and has is covered by multiple patents.

Luc van Bosstraeten,’s GM for Benelux explains. “It is as simple to use as your letterbox, but it contains breakthrough technology. You can use the system to allow package carriers and even local shops – like your baker – to deliver their products at home. The only thing the baker needs is the Parcelhome app. The system is totally secure and works with dynamic codes comparable to the codes used in online banking. The built-in scale issues a receipt, and the system can receive multiple packages from different carriers. As soon as a package is placed in the ParcelHome unit, the addressee is notified.”

This means that customers know exactly when a package has arrived or been picked up and what each carrier has done. Thanks to the scale, it is easy to send and return packages and there is no need to go to the post office. The ParcelHome unit calculates the delivery fee and franks the package, a carrier then comes and picks it up.

The ParcelHome unit is large enough for 95% of packages. At the moment the trial is limited to the homes of 100 online shoppers in the Mechelen area who will be testing the units from May until July.
“It is high time for something like this,” says trial participant Gilles Van der Planken from Duffel. “My wife and I both work away from home. We order items online several times a month, from coffee capsules to nose spray to children’s toys. Having to drive somewhere to pick up a parcel is annoying. I hope that from now on ‘home delivery’ will mean that items are actually delivered to our home.”
It is not surprising that kicks off in Belgium, because e-commerce has huge momentum in the country, and according to research by management consultancy AT Kearny Belgium is among the top ten growth markets. A number Belgian companies have contributed to the development of the smartbox including Quad Industries, Eurocircuits and Clear Channel Belgium. Eurocircuits also takes part in the trial.

But what really makes this project unique is the fact that several different carriers are co-operating for greater customer satisfaction. They clearly see that is key to the future of e-commerce.

NAKED proto

NAKED proto

We have introduced our NAKED proto PCB service to help design engineers who have told us that they need to modify their proof-of-concept PCBs “on the bench” by cutting tracks and soldering on wire-links. Soldermasks and silkscreens make this more difficult, so our NAKED proto service delivers 2-layer boards without mask or legend. Of course, if you need fully finished 2- and 4-layer prototypes, then continue to use our well-established PCB proto service.

NAKED proto brings other benefits:

Almost 50% lower costs:

NAKED PCBs are priced around 50% lower than fully-finished PCBs. As well as dropping masks and legends, the NAKED proto service restricts boards to 2 layers and the quantities available to 1, 2 or 5 pieces. This allows us to leverage the maximum benefit from order-pooling. Also, NAKED PCBs have to start from “known good” data. Before you place a NAKED proto order, you must run your data-set through PCB Visualizer. If PCB Visualizer raises any issues, fix them and upload the data again. As soon as PCB Visualizer confirms that the data is good, place your order.

1 day delivery:

By starting from known-good data and dropping the mask and legend printing and curing cycles, we can offer 1 day deliveries.  Upload your data and place your order before midnight CET and we will ship the next working day by overnight courier.  So if you order on Monday, we will ship on Tuesday and you will receive the boards on Wednesday in all parts of Europe where couriers provide a next working day service.  Otherwise order on 2, 3, 4, 5, 6, or 7 day deliveries.

The introduction of NAKED proto is part of our mission to provide professional PCB designers with the tools they need to develop their designs and bring them to market on time and on budget.  But, as a responsible European company, we also have a duty to encourage and develop new generations of PCB engineers..  We already sponsor student projects all over Europe (see our blogs).  We see NAKED proto as another part of this duty.  We can help tomorrow’s engineers, whether students or hobbyists, by providing affordable prototype PCBs for their personal projects.  Lower cost cannot mean lower quality: they need to debug their designs, not their fabricator’s PCBs.  NAKED proto gives students and hobbyists access to low-cost PCBs of proven quality on reliable deliveries from a leading European supplier, who can also support them with technical back-up from white-papers and blogs to online chat with PCB engineers.

NAKED proto (Spanish)

Lanzamos nuestro servicio NAKED Proto PCB para ayudar a los ingenieros que nos habian informado de que tenían de alterar y cortar directamente pistas y soldermask en el Pcb. El soldermask y la serigrafía hacen esto más difícil, y así nuestro servicio NAKED proto ofrece PCBS de 2 capas sin soldermask y la leyenda. Por supuesto, si usted necesita un PCB totalmente terminado de 02 o 04 capas entonces puede seguir utilizando nuestro servicio establecido,PCB proto.

NAKED proto trae otros beneficios:

  • Casi 50% de reducción en los precios

NAKED PCBs tienen un precio alrededor de 50% más bajos que los PCB totalmente terminados. Además de no tener soldermask y la serigrafia, el servicio proto Naked restringe el servicio a un máximo de 2 capas y las cantidades disponibles son 1, 2 o 5 Pcbs. Esto nos permite obtener un mayor beneficio del “order-pooling”. Además, NAKED Proto PCB tiene que empezar de datos “buenos” ya conocidos. Antes de hacer un pedido Naked proto debe revisar sus archivos a través de PCB Visualizer. Si PCB Visualizer plantea algún problema, debe corregir y cargar los datos de nuevo. Una vez que el visualizador PCB confirma que los datos son buenos, usted puede hacer su pedido.

  • Entrega en un dia:

Al iniciar la orden, sobre la base de datos conocidos y abandonando el soldermask y la serigrafia, podemos ofrecer entregas al día.

Eurocircuits maakt de E&A gadget print en lanceert hiermee: SEMI-FLEX pool

Eurocircuits maakt de E&A-gadget print en lanceert hiermee: SEMI-FLEX pool.

Sinds vele jaren zijn wij trouwe sponsor voor de printen van het gadget dat onze jaarlijkse elektronica-beurs in het Nederlandstalige gebied kleur moet geven. Nog snel een gadget, e-brace, reserveren? Doe het hier!

Deze beurseditie, E&A 2015, is voor ons bijzonder want de print van het gadget is dermate speciaal dat het voor Eurocircuits de start is van een nieuwe pooling service: SEMI-FLEX pool.

De print is een Rigid-Flex waarbij het flex gedeelte geen traditioneel polymide is maar standaard FR-4 met een speciaal bewerkte koperlaag. Dat definiëert de Flex als SEMI-FLEX. Het aantal buigingen en de radius zijn daardoor beperkt (typisch: 5 buigingen van 180° over een radius van 5mm) maar de functionaliteit biedt wel een geweldig alternatief indien men twee printen moet verbinden, aldanniet onder een hoek gemonteerd, en men wil connectoren vermijden. Dat kan verschillende redenen hebben: signaalintegriditeit, plaatsbeperking, kosten, enz…

Hoe ziet de buildup eruit?

In het midden zit een core FR-4 Isola PR370HR 100micron 35/35micron Cu. Dit is het SEMI-FLEX gedeelte met het speciaal behandeld koper waardoor dit zachter blijft, buigt en niet scheurt. Vanwege de mechanische eigenschappen kiezen we voor 35micron Cu wat de patroonklasse beperkt tot klasse 6.

Aan de buitenzijde zitten twee FR-4 cores 360micron dik en 18micron basis koper. Hiervan etsen we een laag weg, zodat we in het totaal over 4 lagen beschikken. (Voor de e-brace kozen we cores van 360micron dik. Voor de SEMI-FLEX pool service zullen deze cores 510micron dik zijn.)

Tussen de cores zitten 2 noflow prepreg lagen van 63micron dikte. Nog voor het persen, frezen we in deze prepregs het latere SEMI-FLEX gedeelte vrij. Noflow betekent dat deze prepregs minimaal uitvloeien tijdens het persen.

Na het persen frezen we diepte gecontroleerd door de buitenste cores waardoor het SEMI-FLEX gedeelte vrij komt te liggen.

Veel meer operaties noodzakelijk dan voor het maken van een 4-laags. Eigenlijk maken we hier een 6-laags reverse buildup waarvan we op voorhand laag 2 en 5 wegetsen. Het verwijderen van laag 2 en 5 maakt de registratie van de ander 4 lagen op elkaar voor het persen iets eenvoudiger.

D&D bestukt de e-brace protos, A1 de pre-serie en op de live line tijdens de beurs, bestukken de gadget partners de resterende hoeveelheid, telkens in een klantpaneel van 3 printen. Het paneeltje ziet er dan schematisch zo uit:

We staan met de e-brace aan de vooravond van een nieuwe service voor Eurocircuits. Wij hopen dat er onder onze klanten voldoende enthousiasme zal zijn om met deze nieuwe pooling mogelijkheden aan de slag te gaan.

Tot op E&A!

New from Eurocircuits at TEC Warsaw 21 May 2015: SEMI-FLEX pool and NAKED proto PCBs

Online DRC and DFM tools to help get your designs to market on time and on budget

At TEC Warsaw we will launch two new PCB prototype services:


SEMI-FLEX pool offers cost-effective 4 layer, flex-to-install PCBs. Instead of two PCBs joined by connectors or cables, design a single SEMI-FLEX PCB and bend the flexible section at installation. Eurocircuits” 4-layerSEMI-FLEX PCBs use a 100 micron FR4 core with two specially treated copper layers, designed for bending during assembly but not for dynamic flexing. You get lower product costs (no connectors, no cables, less assembly time, no expensive polyimides), faster assembly and increased product reliability. Samples and technical specs will be available on Eurocircuits stand #6 -7. The service will be available on the Eurocircuits website with full technical back-up from the beginning of May 2015.

NAKED proto

A new service aimed at engineers who want a fast proof-of-concept board that they can modify on the bench with wire-links or cut tracks. NAKED proto boards are supplied with no soldermask and no silkscreen on deliveries from 1 day and at almost half the cost of fully finished PCBs. Students and hobbyists can also benefit from the low prices and short deliveries from a reliable European supplier. Prices will be available at TEC – and on our website.

Online DRC and Design for Manufacturability tools – share our knowledge

Hard-pressed designers don’t have the time to understand every aspect of PCB fabrication that affects the cost and delivery of their PCB. Our online DRC and DFM tools give you practical access to our PCB knowledge from the very start of the design process. Smart menus validate your design parameters and guide you towards the most cost-effective choice. Our PCB Visualizer range of tools check your data before you place your order. That way you are sure that there are no data issues which will delay delivery. Our forthcoming PRE-CAM software will show you exactly how we will make your board, so that you can approve everything before we start production. Dirk Stans, Eurocircuits’ Sales Director, will present a seminar on how to use these tools to optimise your PCB design process and get your design to market on time and on budget. And he will be on Eurocircuits stand #6 – 7 all day to demonstrate the tools.

Forthcoming developments: eC-placer

For a long time our customers asked us for cost-effective precision assembly and test equipment suitable for prototype PCBs. In response, we developed the eC-stencil-mate solder-paste printer, the eC-reflow-mate reflow oven and the eC-test-mate for functional testing without expensive test-fixtures. In June we will fill a gap in the range with the launch of the eC-placer, a precision guided manual assembly table, using either camera or copy-paste technology for high-accuracy placement. Visit our stand for more on all our equipment.

Visit our stand #6 – 7 at the Conference. You will need to register as a visitor beforehand. You can do that here. Please mention Eurocircuits while registering.
