Flexibility Needed

Traditionally we have designed and used electrical devices based on non-flexible PCB’s. They have many advantages, one of the biggest is the easy manufacturing. Feels like any street corner has a small company, who can manufacture FR4 based PCB, pick’n place the components and deliver them to our customers.

We have changed our attitude

Nowadays, we as customers, are not willing to carry heavy external electronic devices. We want them to be integrated to our clothing and to our behavior.

At the same time, we wish our devices be more independent and more aware of surroundings. We don’t want our applications give our personal data to anybody, except for our friends in Internet.

And we should not forget our attitude for maintenance; we wish that the device does not need to be charged, configured or interacted in any way. It should just work out-of-the-box.

What to think?

Customer needs are challenging, and most the requirements are such that nobody is willing to pay for those. Unless they suddenly become really important.

Starting with small steps, one could analyse that is the device better, and is the customer therefore willing to pay more for it, if:

  • Is it lighter? saving weight saves resources and is also ecological thing. Also transportation of device is cheaper.
  • Is it flexible?
  • Is it integrated into customer surroundings?
  • Is it protected from RF interference?

If the answer is YES, to any one of those questions, perhaps it would be the time to look for ways to make your application more flexible. Since those are the main benefits of SFFC cabling enables.

IoT means RF


When we think about IoT, we often forget that we are usually also talking about wireless communication. Even though we are protected with legislation, which controls the power and frequencies of communication between devices, problems may arise. Our message in short is:

The more there are devices sharing frequency channel, the more disturbed the channel is.

In the old era of computing and communication studies, Shannon and Hartley studied and defined “the maximum rate at which information can be transmitted over a communications channel” (nice sentence from Wikipedia).

IoT is about wireless – is it?

If I start talking you about new IoT application (or device), first visualization which comes to your mind, is most likely wireless device. Even though IoT (Internet of Things) actually stands for devices connected to internet. As term connected implies, some networking is involved. However, it does not imply wired nor wireless networking. We have just been so often talked about wireless IoT, that we always assume that everybody else is talking too.

Most important challenges in IoT are power and communication. If we are using wired communication, it is very convenient to use parallel wires to power the device. When wireless communication is used, batteries are used most often. This can change very quickly, when solar powered and wireless powered devices become more common.

Every open wire, which transmits alternating current, usually called signal, is a sending antenna. And every open wire is receiver antenna, whether it is sending or not. If the open wire has a a signal, and there are powerful enough RF around it, the resulting signal (measured from the wire) is the sum of signals (original signal and received signal from antenna).

Wireless is Shared Channel

When we are talking of wireless IoT, we are talking about shared channel. All wireless devices which are communicating wireless using same bandwidth can be heard by other devices. In this I refer to radio signal, not the data, which should be encrypted anyway. Radio signal is the media and data is the payload.

Like in football game; the more there are viewers shouting at the same time, more difficult it is to hear the actual message, unless the message is same. In IoT it usually is not. With a number of sensors, a number of different measurements should be received.

When we wish to overcome the disturbance of signal “next door”, we usually just turn “up the knob”. In IoT, this is impractical solution, since using more power to radio means bigger power consumption. And since most IoT devices don’t have external power sources with infinite capacity, that would mean running out of batteries sooner.

How we can protect our wireless IoT devices? The normal way:

  • Choose radio protocol and frequency with care
  • Design IoT device with care
  • Shield the electronics from RF with casing
  • Only antenna(s) should be outside of the shielding/case
  • Use shielded cables when transmitting data from PCB to PCB, if there is any possibility that the open wire would act as antenna


Updated Jan 16th 2018;  I re-wrote some of the article, to emphasize more that IoT is not totally only about wireless.


Here we go again, LOPEC’2017 is just starting. We have arrived into lovely, sunny and warm Munich again. Our hearts are full of confident and wonderful ideas. The conference has alread started and the exhibition starts tomorrow.

Front entrance to the LOPEC exhibition.

We have placed the posters in the poster area and here you can see Antti showing off the Delektre poster. If you look carefully, you can also see the NCC poster in the background. The bright orange poster calls for attention. We are really happy for the print work of the local print-shop. The colors are just what we wanted, and the paper quality is superb.

Antti is showing the only poster in Business Track.

This year we do not have booth at LOPEC, but come and join us – we will be wearing our hats.


Prince’16 – See you next time

Thank you for PrintoCent -folks for organising really great event in the right time of the year at Oulu. The program was smashing and there were a lot of interesting talks. Again thank you for all the visitors in our booth at Prince’16. Hope that you has as good time as we had. We had great week at Oulu – combined with the Innofest’16 and Midnight Pitch. The printed electronics superweek was once again success. For all the new ideas you will hear in the future.

The nights at oulu are really bright, the following photo could have been taken at 4am, and just to be sure, we were awake at 4am. But of course I forgot to take the pictures at time.

The summer nights at Oulu are quite bright. This picture was taken 11pm.



IDTechEx Berlin 2016 – Thanks

The IDTechEx Europe 2016 held in Berlin, Germany is now over. We wish to thank all the visitors, customers, dealers, agents, new connections and old friends visiting our booth and of course the organizer IDTechEx for putting it all together.

Exhibition visitors

The exhibition was a great success and gave us the opportunity to showcase some interesting items. For again, I didn’t have enough time to visit all other booths at exhibition, but I managed to be involved in interesting dialogs at our own booth H02.

I hope that you had as much fun as I had when touring around the exhibition and listening the conference presentations. We (as the industry) have some really interesting things cooking on.

Random Exhibitors

If we didn’t cover all the questions or if there were any unanswered questions raised by my presentation, please, do not hesitate to contact us

With the Very Best Regards,


Thank you EnergyWeek @Vaasa

This week we were attending at Vaasa #EnergyWeek, we followed the seminars, took part in forums and were involved in other program. I wish to thank for the organizers for putting up such a great event and I really hope that you do it again next year.

Also I wish to thank everybody I met at Vaasa. It was really great to meet you and I hope that the feeling was mutual! Maybe I was able to contribute to some new ideas for you too.

Yours, Tommi

New Cable Corporation is in business

New Cable Corporation is a Oulu based Finnish startup company, spin-off from Delektre. Together we have more than 30 years of experience in cabling. Our mission is to change the world, one cable at a time. Now we have a website up and running, as you can see, if you are reading this.

As first we will bring you a different USB cable. As can be seen in the feature picture, the new cable will be flat. The world might not be flat, but cables should!

Follow us and our journey to develop new things in cabling.


Tommi (CEO)
