I am PhD in Electronic Engineer with more then 20 years professional work in electronic field. Worked as Head of R&D and main hardware engineer for more then 10 years. I have many experienced for this job. I am a professional Engineer in this field and I would like to give my best service and High quality to the PCB projects and electronic design projects in general here in Upwork project. I run own R&D company where I was involved in many serious projects, especially for industrial with high standards for EMC and LVD. I am also experienced in EMC design and passed many testing in labs. -Our hardware design expertise covers a variety of products across different customer and industry domains - Board design/circuit design - Component selection - Platform selection - PCB design, multilayers, impedance control, flex-rigid design - Prototypes - Mass production support, PCB and PCBA service in Europe I also cover Embedded software development and interaction with mechanical design SolidWorks etc... so I can provide full service. In my portfolio you can see some recent works. Most customers are from Switzerland, UK and USA, but have also from different countries. I made jobs for important customers like: - G&W Electric Co, IL, USA - Profitoptics Inc., VA, USA - Gold GMT SA, Switzerland - Swisscom AG, Switzerland - PlayDate, NY, USA - Netico GmbH, Switzerland - Airwave Solutions Ltd., UK - Nitto BioPharma, Inc., USA - RUAG AG, Switzerland I done lots of projects, example for USA main company we are working for is G&W Electric Co, Bolingbrook. They are one of main switchgear producer in USA, has about 70% market. Then permanent cooperation with ProfitOptics Inc. Glen Allen, VA. Then Mr. Kevin Li from New York University Most projects we do complete solution hardware and firmware. I attached you for example last board for mobile phone, 8 layers, wire 3mils, vias 0.1mm. Of course can show you more, always ready for agreement. About your project, we done few very complex designs. One is RTU system with analog inputs, analog outputs, digital inputs, digital outputs. That kind of device is sold to Voith company which produce hydro turbine. It is industrial grade device, in all aspects power supply, working temperature. Passed tests. Second is SDM board you can see. It is for G&W company driving switchgear. High class industrial environment. We passed tests, which are very high vs European, and of course it is class of tests for Relay protections.: 1. IEEE C37.90.2 – 2004 – Radiated Electromagnetic Interference 80-1000MHz, 1kHz AM Modulated, 80% keying, 35V/m 2. IEC 60255-22-2 – Electrostatic Discharge Level 4 contact and air discharge, +/- 8kV, +/- 15kV 3. IEEE C37.90.1- 2002 Surge Withstand Capability IEEE Standard for Surge Withstand Capabilities (SWC) tests for Relays and Relay System Associated with Electric Power Apparatus. +/-4kV EFT, +/-2.5kV OSC 4. IEC 61000-4-6 RF Conductive Immunity 150k-80MHz. 10V/m Always can show you more. Thank you for your attention.
