Design of electrical circuit diagram
Designing a circuit diagram is (not always) the first stage in any electronic product. Using the latest schematic and simulation tools, we convert your concept or idea into a schematic circuit diagram.
At this stage of the design process, we consider component costs and availability as a high priority. Where possible, all or parts of the circuit will be simulated to evaluate and test performance before hardware is produced. A bill of materials (BOM) can then be generated, allowing you to start looking for quotes from your chosen manufacturer.
Our experience and know-how ensures that your product idea comes to life quickly.

Rapid prototyping
To effectively manage resources and minimize costs when creating a new product, modifying an existing one, or testing an idea, the right step is to test with a prototype. Depending on the stage of the project, testing can be with a prototype circuit board, a functional printed circuit board, and a finished printed circuit board.
EARLY PHASE & IDEA TESTING
We create a conceptual mock-up or prototype that provides a basis for exploring the idea of a product or upgrade. For the hardware, we use ready-made components, modules and development tools. For firmware and/or software, we use free, open source software and services. The aim is to explore the possibilities of the idea, the methods and the technical challenges before its implementation.
ADVANCED PHASE
We create a working prototype one step before the final version. The hardware is designed according to the customer's needs. We develop and test basic firmware functions We create a functional prototype that works sustainably and can be used for demonstrations or further development of the idea.
EMC (electromagnetic compatibility)
Electromagnetic compatibility (EMC) is constantly increasing in importance in all areas of electronics. Regulatory norms are becoming increasingly strict. This increases the time and effort in the design process of an electronic device to be able to achieve a design that meets the relevant standards. It is very important that the design is tailored to the specific requirements from the very beginning in order to avoid unforeseen costs at a later stage.
A proper understanding of EMC can increase the quality of the products offered and at the same time significantly reduce the cost of production. In most cases, the understanding of the problem comes down to good protection, through additional filters, shielding, multilayer PCBs, etc., but this only masks its effects. In some of the cases, the protection will help, but from a global point of view, the effect of this protection is to increase the cost of production and the price of the device, and the problem is not completely eliminated, and it is a prerequisite for future unforeseen costs. The correct approach is not to fight the consequences, but to eliminate the cause of them.
IN PRACTICE
Often in our practice we come across the understanding that the way the printed circuit board is designed and wired cannot influence the problem and it is solved with a "big" choke at the input of the device. This is wrong and in all designs leads to an increase in the cost of the product. In most cases, the large choke is replaced by a "thin" printed circuit in the right place, allowing the currents to close a minimal loop on their way from the source to the drain and back.
WHAT WE OFFER
You get our support from the very beginning of the project in the design of the schematic diagram and the printed circuit board. You minimize the number of necessary design revisions until reaching the correct design covering electromagnetic compatibility norms. If you use our hardware design services, you get the consultation along with the service and it goes hand in hand with the project until its completion.
COMMON PROBLEM
In the figure you can see the PCB wiring and the measurement result. Unfortunately, the problem was solved at additional manufacturing cost by adding a choke to the device's power input and adding two more layers to the PCB.
A "ZERO" COST SOLUTION
In the figure you can see the wiring of the PCB as with only a very small change - adding a thin PCB wire in the right place solved the problem with zero production costs!
