Electronics

The electronics division of Sioux Technologies develops, builds and integrates advanced electronic modules and provides electrical engineering of high-tech systems for the highest achievable performance.

DEVELOPING, BUILDING AND INTEGRATING ELECTRONICS FOR THE HIGHEST ACHIEVABLE PERFORMANCE

  • ELECTRONIC MODULES 
    High-quality electronic modules, usually in assemblies with mechanical and software components in complete subsystems. Developed and industrialized for accuracy, stability and speed.

  • ELECTRICAL ENGINEERING

    The electrical infrastructure around the system, mostly electrical cabinets, for efficient and robust power supply, control and safety.


SOFTWARE CHALLENGES

INCREASING TECHNICAL COMPLEXITY

Products are becoming more accurate, faster, more intelligent and more independent. That places increasingly greater demands on electronic subsystems.

CHALLENGING PHYSICAL CONDITIONS

Vacuum operation, thermal behaviour and vibrations make functional, reliable and robust high-tech electronics a specialty.

VERY LIMITED SPACE

Electronic components often need to be small, because the physical space inside the system is severely restricted.

MULTIDISCIPLINARY PERFORMANCE

System performance is determined by a complex interplay of mechanics, electronics, software and mathware. Finding the best electronic solution requires system thinking.

Projects

Phenom Xl

Table-top electron microscope

The customer’s challenge Phenom-World’s goal was to build the first personal table-top electron microscope. Sioux's contribution Sioux developed the complete software suite for the Phenom. This includes hardware control, image processing (Pro-Suite), user interface and multi-language support. Sioux also developed all electronic hardware (including high-voltage electronics and the wiring) and produced and tested all electronic boards. On top of that, Sioux created the mathematical algorithms and the remote diagnostics. Result Phenom-World is now a leading global manufacturer of desktop scanning electron microscopes and imaging solutions for submicron scale applications. Technology Embedded Linux, C++, Windows, C#, .NET, WPF, SOAP, Altium, DSP, ASD, Zynq, PCB layout, analogue-, digital electronics, simulation, microcontrollers, assembly, testing, mathware technologies: image recognition, openCV, machine learning, convolutional neural networks, Python, Matlab, heuristics and web technology.
Liteq 2

Wafer stepper electronics

The customer’s challenge Kulicke&Soffa developed the Liteq 500, a wafer stepper for the Advanced Packaging market. Two of its subcomponents need to be controlled with deterministic timing using dedicated hardware: the Metrology Unit (MU), which samples the Aerial Image Sensor, and the Illuminator Control Unit (ICU), which controls the laser. Sioux's contribution Sioux designed and developed the PCB for the MU and the ICU. Before and during development, Sioux advised on EMC issues and proposed several improvements to increase testability and reliability. Sioux lowered production costs by developing only one board suitable for controlling both the MU and the ICU. Furthermore, Sioux developed the real-time microcontroller software running on the boards as well as producing, testing, and delivering the boards. Result The PCB is now part of the first functional stepper developed by Liteq. Technology Altium, STM32, Sioux ESP, Keil MDK, C++ and real-time processing.
Nemo 03

Fetal Monitoring System

The customer’s challenge In 2005 Nemo Healthcare started to develop a method for monitoring the condition of the unborn child by means of non-invasive electrophysiological recordings. From these recordings, which are performed on the abdomen of a pregnant woman, information is obtained both on mother and fetal heart activity and on uterine activity in a non-invasive and comfortable manner. Electrophysiological monitoring provides more accurate information than existing non-invasive monitoring technologies. Moreover, it delivers unique information that other methods cannot provide. Sioux's contribution Sioux developed the Nemo Fetal Monitoring System NFMS, containing two front-end headboxes and a base station. The headbox contains sensitive analogue electronics, an ADC, a microcontroller with embedded software and a Bluetooth Low Energy chip for wireless communication to the base station. In this base station, the fetal heart rate, the mother’s heart rate, and the mother’s uterine activity are extracted from the measured signals. The base station can be connected to different CTG monitors. Sioux assembles and tests the NFMS, fully in accordance with ISO 13485. Result Nemo Healthcare moved from a proof of concept to a product that has been CE-certified in 2019. Technology Amplifiers, filtering, 16 bit ADC, Bluetooth Low Energy, Fibre optics, ARM Cortex M3 microcontroller, Altium PCB layout, C, C++, Linux Yocto, QT, Sioux SCAP platform, Assembly and test.
