Position of Technician.

SUMMARY OF QUALIFICATIONS:

- Worked with analog, switching and RF circuits in the range from microvolt and nanoampere level to 100kV and 200A, from DC to 400 MHz; digital including microprocessors, FPGA and DSP.

- Test and troubleshooting of the boards, sub-systems and systems to the component level and to the root of the problems. Diagnose/analysis and revealing problems related especially to tuning, time delay and timing, impedance, coupling, grounding, noise pickup, temperature, Trr, switching loses, combined electronic/mechanical assemblies and help with solving of them.

- Self-motivated experimentalist. Prototyping and assembly of the boards, sub-assemblies and systems including work from schematics, drawings and verbal instructions. Modification and rework boards including “surgery” of multi-layered ones.

- Experience based on understanding physics and theory of schematics and components behavior especially for high/low current, high/low voltage and RF electronics.

- Proficient in test equipment including digital/analog oscilloscopes and multimeters, function, pulse and RF generators, spectrum/network and power analyzers, time/frequency measuring instruments. Fixed some of them.

- Understanding concepts of dynamic performance and stability in the real time of motion control servo electromechanical systems with closed loop.

- Experience with equipment used for processes control and in material science environment, sensors, measuring and recording instruments.

- Knowledge of specifics of copper base alloys used in electronic industry.

- Good soldering/desoldering technique including SM parts.

- Mechanical skills include good manual dexterity, using hand and power tools, lathe and milling machines.
