Design linear and switching power amplifiers, voltage / current sensing instrument up to 5kVrms and 200kHz, and embedded PC/104 computer system. Applications included sonar and low frequency radio transmitter system for defense industry.

*Sustained California Instrument brand and AMREL brand products engineering activities. *Designed deviated models with modified harness, circuit, PCBA, firmware, BOMs, specification, manual addendum, assembly documents, test procedures, labels for non-catalog sales orders. *Designed 9600L model and passed shock/vibration test, a programmable AC source with single phase output up to 1700Vac 9600VA specifically for petroleum fracking application. *Designed and released PD series product line, over 30 models. Single channel output from 60W to 2000W and up to 8 channel output in a 4U full rack. *Developed a Digital Fault Monitor Kit as a critical feature for RS series. The kit included a rear panel channel switch and a fault detection board that set up multiple fault conditions to monitor and communicate each status to the main controller using I²C bus. This critical feature allowed user to query status of added fault conditions and optimized system safety as already demanded from multiple key customers. *Reengineered RS series Amplifier from component to chassis aspects, that reduced total MLO cost by at 30% per unit. Passed EN55011 radiated and conducted emission test at TUV lab. *Performed onsite engineering activities to resolve escalated technical problems from key customers such as Lockheed Martin, Delphi, Raytheon, LGE, VEECO, TSMC and more. This have secured repeat orders from key customers. *Engineering support for critical, obsoleted or long lead time electronic components by providing design verified sustainable solution. Resolved many production line down situations. *Identified improvements for existing products related to electrical/firmware/mechanical, and then verified and released changes. Those improvements included cost reduction, increase reliability and functionality.

*Defined assembly/testing standard for each AMREL product, good for MLO calculation. *Test station layout, one computer test technician controls two automated test systems. That reduced automated testing process time by 33%. *Learned and executed 5S concept on AMREL floor. *Collected data on daily production defects and the time consumed. Generate weekly analytical report with proposed corrective actions in order to bring down the defective rate. Average of 75hrs that production spends for troubleshooting and rework defects per week. *Learned and executed the Red Light concept. Invite associates to facilitate investigation of the red light event while exchanging facts/details/knowledge to ensure corrective action is successfully carry out. *Transferred PCBA functional test knowledge and firmware loading process to PCBA department. This is leveling the work load on box level testing. *Generated engineering change request *Maintained and updated standard testing procedure.

· Provide direction and priorities to all level technicians and Manufacturing Engineers.· Accumulated strong electrical, mechanic, safety, and thermal knowledge by integrate power systems.· Lead a team of 5 to conduct Preventive Failure Mode Effect Analysis. Weekly review the occurrence probability, severity, and detection methods of each failure mode occur during pilot run, production or RMA process, and then prepare monthly failure/risk analytical report for Design Engineering and QC.· Responsible for coordinating activities concerned with technical developments and scheduling.· Effectively communicate with internal/external customers regarding project goal, status and general inquiries.· Improve manufacture productivity and traceable performance measurement using M.S. Project and M.S. Excel.· Validate engineering drawings, testing reports, bill of material, and engineering change requests.· Completed Project: Utilized all engineering resources to design a user programmable control panel integrated within Magna Power Electronics power supplies to add Ethernet, GPIB, USB, and RS-232 remote interfaces capability, and successfully transferred this prototype to production.· Proposed and implemented a completed calibration plan that successfully lowers the testing equipment maintenance fee by 30% annually. This plan included a detail calibration standard procedure, checklist and calibrator requirements for all in-house testing instruments: such as oscilloscope, bench top multi-meter, current probes, precision current shunt, wide band spectrum, and etc.
