In our business, we are having a special focus on cell contact systems (CCS) for high-voltage batteries. These systems are used to connect the individual cells with the BMS – Battery Management System to control and monitor the battery.

CCS are designed with a flexible printed circuit board (FPC) with contacts, that allows several functions, especially monitor the voltage and the temperature of the cells. Capacitors are soldered to the PCB and fuses are integrated in the design. Connectors interface to the BMS.
The high-reliable cell contacting systems made by ElectronAix are an important element of modern electric mobility and are designed for the use in the automotive industry. All of our CCS are produced in an IATF16949-certified and VDA-audited production facility and are suitable for use in automobile and industrial applications. Our cell contact systems are an optimized solution for the latest generation of high-voltage batteries as they are used for electric vehicles.

We have references from well-known battery manufacturers whose products are applied in the cars of the leading automobile manufacturers.
We have the highest demands for the quality of our cell contacting systems. An IATF16949 approved and audited production in a state-of-the-art production facility and the latest testing methods are the basis for the high-quality products made by ElectronAix. Thus, our systems easily meet the quality standards required by the leading automobile manufacturers in any way.
With our many years of experience and expertise in this business, we support you to find the perfect solution for your cell contacting system – from the first idea to the completion of the design. This includes:
  • the selection of components,
  • the layout of the circuit board,
  • the integration of fuses into the layout and,
  • the selection of the connector to the battery management system.

You are welcome to contact us, so we can find the best possible design for you.
Flexible printed circuit boards are connecting elements with an etched structure. Depending on the application, the printed circuit boards are equipped with components or serve as pure flex foil to connect two FFC/FPC connectors.

The base material is polyamide and allows operating temperatures of up to 150°C. Complex structures and small tolerances can also be realized thanks to the etched structure.
Just like our CCS, the flexible printed circuit boards from ElectronAix come from an IATF16949-approved and VDA-audited production facility. They fulfill all requirements for usage in the automotive sector – especially for battery electric vehicles (BEV) – and for industrial electronics.
You can fully trust on our experience and expertise when it comes to designing FPC. We take you through the whole process from your idea to finishing your individual design.

Upon your request, we also realize designs for high data rates, for example for PCIe, CAT6e, USB4 and others. You get exactly the best-fitting flexible printed circuit boards for your purposes – custom tailored and with a high reliability.
More than 20 years of experience with electrical connection technology - with our knowledge we support your design. Since we cover all technologies - FFC, FPC and cable assemblies - we will support you openly and find the best solution for you, including the connectors. As a result, this makes your project moving very smoothly and reduces your time to market. We offer you high quality FFC/FPC connectors from IRISO and I-PEX as well as from our own brand from Asia. We help you from the design-in to the end of life of your project.

SAP is our most important tool

We work with an ERP-system from SAP and map all flows of goods there, from the procurement of raw materials to the storage of raw materials, the inventories in our buffer warehouse in Aachen and all the way to the deliveries of your orders.

Our ERP-system thus combines all the functions we need for our business operations, ensuring maximum transparency, and data integrity.

Documentation and data security

The most important information about the article life cycle is integrated into our ERP-system: Clarifications and technical changes are thus accessible and available at any time if required, for example during order entry.

To ensure the highest level of data security, our server is mirrored, and both servers are also housed in different fire protection areas. In addition, all data is backed up daily to a German cloud. An external partner keeps our firewall and virus scanner permanently up to date.

Project planning and buffer storage

We have critical components in stock on site in Aachen. This gives us 100% control of material management and - flow. During the ramp up we can agree with you on buying critical parts from the BOM-List in advance. This supports a smooth project ramp up and maximum supply security for your benefit. It gives you more time to finalize the design of your assembly.
During the lifecycle we can keep a buffer stock of the critical components. This shortens lead times gives you flexibility.
In case of minimum order quantities e.g. for raw cable, we can arrange to keep the surplus in our factory for future orders.

Origin of supply

We mainly work with companies that are based in Taiwan. There, we focus on a small number of experts. Most of them have production lines in China (Mainland).

Short time to market

Many years of experience, attention to detail and passion for our products will quickly help you to find the cable assembly with moulded connectors that is precisely tailored to your needs.

We aim to quickly provide you with helpful information, the right drawing and appropriate samples. This reduces your time to market. Our buffer stock of connectors, contact systems and cable assemblies help you to find a solution quickly and to achieve short delivery times.

High Quality

ISO9001, ISO13485 and IATF16949 certified production lines are indicators of the high quality standard of our products and ensure your safety and satisfaction.

All products come from a largely automated process with automatic soldering and crimping and 100 percent electrical testing. Our distribution and logistics processes are certified according to ISO9001 and audited according to VDA.


You require specific tests, such as bending cycles, lengths or test reports? If so, ElectronAix is the perfect partner for you. We will coordinate all details with you individually.
