Hardware Development
We use the Altium Designer software environment for PCBA design. Depending on the defined requirements, number of components, purpose and price, the type of printed circuit board (single-layer, double-layer and multi-layer) is determined.
Before starting the production of an individual product, the development department together with the production experts configure the optimal panel of printed circuit boards (PCB), thus ensuring fast and optimized production.
We use different sizes of electronic components. They depend on the print size and component density. We use all sizes. Relatively large SOIC components, up to 100 or more pin microprocessors in a TQFP or BGA case, and small integrated circuits of the order of 2x2mm or more in a QFN or DFN case. The smallest passive components we use are 1mmx0.5mm in size.
Software/Firmware and Application Development
We work with various software solutions and to develop software/firmware for the final product. We use the C programming language to program embedded systems. When developing microcontrollers, the use of the software environment depends on the microcontroller manufacturer. We most often use Atmel Studio, but we also use Eclipse, STM Cube and Keil.
We use Python, C# and C ++ when programming software for personal computers. If necessary, we also use other scripting languages for certain projects.
Development Testing Devices and Fixtures
As testing is one of the most important segments in the development and production of printed circuit boards, we develop custom testing devices. Test devices enable the verification of many parameters, including:
- Current and voltage
- Luminance and wavelengths of optical fiber LEDs connected to specific optical sensors or other optical units
- Button activity
- Sound quality and length
All the listed parameters are measured at predetermined points and are transferred from the printed circuit board (PCB) in the test device to the personal computer via a serial or other type of interface. The computer provides the test engineer with data on the activity of a certain part of the device, the values of the measured parameters and their suitability, the necessary interventions to achieve better results, and more. The obtained data, including the serial number of the tested electronics are stored in the system so that the parameters can be traced if necessary.
The tested electronics are inserted into a test fixture that has test pins connected to the control electronics and consequently to a personal computer. This method allows fast and effective testing, repeatability of the test and less stress for the tested electronics. This also greatly reduces the possibility of human error in testing, as the entire procedure is predetermined and fully automated in most cases due to program management on a computer.
Upgrades, Updates and Redesign
We also specialize in providing modifications and updates for existing products. In this way, we achieve optimization and full utilization of products, cost reduction and adjustment to market requirements.
The process begins with a detailed inventory of the necessary changes and elements that work well and the customer wants to keep. If there are few such elements, the client is immediately offered the production of a new product, as the modification would not be cost-effective.
We also help companies with a long tradition of operation, which have been using the same, now obsolete, type of electronics in their business systems and production lines for decades. In case of defects, they do not find suitable spare parts and components on the market. We carefully assess the condition of existing electronics, perform all necessary measurements and inspect the operation of individual components. Then we produce updated versions of existing components with detailed specifications and functionality that meet the modern requirements and standards.
