Electronics design

 Design of electronic and programmable systems is based on the following components:
- standard digital circuits and single-chip microcontrollers (C51 family, Microchip etc.)
- digital circuits with signal processors
- FPGA and CPLD design using VHDL, behavioral simulation of the design, testing
- a multi-layer PCB design
- electronic circuits for the PCI bus, including control software development
- analog circuits design, behavioral simulation using the PSPICE-compatible simulator




Software development

The design of software is focused on control and data processing for aerospace, communications or process control, including efficient man-machine interface.

The software development team provides:
- single-chip microcontrollers programming in C language and assembler
- signal processor programming in C language and assembler
- development of user-specific applications for PC




Mechanical Design & Manufacturing

The design of the parts and/or entire mechanical systems is realized using CAD/CAM systems with electronic data formats exchange.

Mechanical manufacture is outsourced in facilities, qualified and certified in the field of aeronautics and space production.

Available technologies:
- CNC machining
- alodine
- anodisation
- electron beam welding
- glass feed-through manufacturing
- thin layer sputtering
- alodine in aerospace quality
- laser-beam cutting



Design Verification

The design is in all projects submitted to verification using mechanical and thermal analysis based on finite elements method.

Parameters are verified to allow safe operation in the space conditions, according to temperature range in the satellite in space, vibrations during the launch phase.

Testing procedures for thermal vacuum and mechanical vibrations tests is a standard.


High-reliable assembly in a clean-room

CSRC clean-room facility class D 100 000 meets the needs for manufacturing of high-reliable electronic and mechanical systems requiring high level of cleanness. The facility is certified according ESA standards.

The operators are trained in Italian and German space industry for more than one-year period, they are certified according ESA standards in PCB assembly, treatments and related technologies.

Available technologies:
- thermal pre-soldering processes - degolding and pretinning component lead;
- soldering of through-hole components;
- soldering of SMD components;
- fine pitch soldering;
- fine mechanical operations - frame, fasteners installation, riveting;
- treatment, cleaning, nitrogen drying, polymerization;
- mechanical pre-soldering processes - preforming, bending, cutting of component leads;
