Welcome to Contronix

We develop the electronics inside of innovative products.

Contronix is a task force of six highly skilled experts that find unconventional solutions for almost any electronic problem. We worked on many different fields like RF, power electronics, or analog circuits and are always open for new things. Almost any development project we’ve worked on so far took profit from our holistic approach. We have a successful track record of more than 15 years in this business.

We don't guess, we simulate.

Every critical part of a new customer project is simulated utilizing state-of the art methods as FDTD, FEM and SPICE.

This approach gives not only more confidence into the design process but also accelerates the whole project by reducing the time to market.

Almost any physical aspect like analog or digital circuits, antennas and thermal behaviour can be simulated.

The most important aspect of electronics is mechanics.

The circuit boards of today need to fit into complex enclosures. Positioning buttons, displays, connectors and layouting internal wiring brings further challenges.

We use a state-of-the-art software that is capable of true three-dimensional circuit board layout. High sophisticated solutions (e.g. complex folded flex-rigid circuit boards) can be designed with a high confidence regarding perfect fit and mountability.

Integration into customer defined enclosures is as easy as exporting precise 3D models of electronic assemblies for further usage in the mechanical design workflow.

Some code brings it alive.

Today almost all hardware needs software to run. The so called firmware is an integral part of an embedded electronic system. We have developed our own special technique to develop the firmware of such a system as fast and as robust as possible.

To make this possible we use object oriented C++ programming, even on small microcontrollers. This makes our firmware deeply structured and easy to maintain during the whole lifecycle of a product.


The things, we're best at and the tools we use

Following the basic circuit design the most critical parts (e.g. power supply) are examined using SPICE. We like using PCB antennas for RF designs as they are almost for free. Their basic design is analyzed using FDTD. For high power applications we can simulate the real current flow using FEM methods on simplified designs, but as well on the final layout. In addition, critical thermal characteristics can be simulated and adjusted.



We're experts using Altium Designer for PCB Design. Over the years we created a vast library of parts fitted to our own needs. All parts contain accurate 3D models for leveraging all the features of the excellent 3D support of Altium Desinger.

With the ascent of 3D printing, we often design small enclosures and support parts using standard CAD programs ourselves.



To track the progress every single item we work at is kept in our version control system using subversion. This is linked to our project management platform. Customers get access to this web based project management system and all their project data around the clock. This powerful combination of versioning and collaboration makes our services as transparent as possible.

Whereas quality control for mass production is very important, it is time consuming transferring data and organizing assembly at a manufacturing service. To accelerate development, we have all tools in-house for assembly of samples. With the help of some well engineered tools the results of this sample manufacturing process are comparable to a following mass production.



We have established a network of powerful partners. Is it mechanical manufacturing, EMC measurement, component sourcing or electronics manufacturing services. If you decide to work with us this whole network is open to you.
