I am seeking an Electrical Engineering position to match my skills in manufacturing engineering, ion implant tools, servo control systems, electrical systems engineering and analog and digital design.

Most recently I was working as an Electrical and Software Engineer at Axcelis. I worked closely with HCL in India to manage ion implant parts using Glovia and SmarTeam. I also worked closely with Axcelis materials/planning/purchasing departments to manage and approve parts replacement and sourcing for the ion implanters. I structured new parts and associated circuitry, drawings, harness assemblies and installation procedures to update tools in the field and/or the production line. I produced documentation for electrical parts and assemblies for release into medium volume production systems. I also worked with the senior scientist to resolve a customer issue for the reduction of emission current on the ARC chamber due to aging and also elimination of the leakage current through the sensor board. I supported the software engineers to merge the turbo PMAC software to power PMAC due to turbo PMAC CPU overload. The turbo PMAC controls the wafer handling robots during ion implant. I was assigned to modify software and hardware to turn off all of the Copley motor’s amplifiers during a macro ring error using power PMAC Ethercat. I was assigned to diagnose customer data error logs by utilizing Matlab, Visual Basic and IBM Rational Team Concert to create CRs and modify the software accordingly. I preformed robotic teaching for new software release and hardware configurations. I worked closely with the senior scientist to resolve customer requests and field issues for Purion tools. I worked with the supplier to improve the reliability of the high voltage ion beam scanner power amplifier. I also redesigned and tested a stepper motor driver card for a three axis robot controller to incorporate replacement parts. I upgraded a Magnetron high voltage power supply and crystal detector power monitor for a Purion ion implant tool.

Throughout my career as an engineer in the aerospace and ion implant industry, I supported internal and external customers by improving the manufacturing yield of the products by statistical process control, modifying circuit functions and replacing obsolete parts according to customer needs. I worked closely with internal customers to implement the changes in the circuit drawings, customers’ manuals and QA approval processes. I performed tests, failure analysis and documented the generated technical data according to engineering policies and procedures. I have participated in the development and reliability testing of circuit boards, controllers, and electro-mechanical assemblies. I have knowledge of high voltage power supply design, laboratory instrumentation and software. I have experience with servo control loop analysis and design. I have robotics experience with motors, encoders and controllers. I have excellent verbal and written communication skills, a strong track record of results, and problem solving skills. I enjoy working with customers and engineers. I have worked with product development, manufacturing, sales and product field support to bring products to market and to support the products.

I resigned from my engineering position at GE aircraft engines in Lynn, Massachusetts in 2001 because of my husband’s job in Tucson and our daughter’s birth. During the past fifteen years I have been busy raising our daughter and doing community outreach work with her schools, Girl Scouts STEM program and teaching.

I hope this summary is helpful. Please contact me if you need any additional information. Thank you for your consideration.
