Rutgers College of Engineering

SKILL SET:

1)Program Management – I recently received a certificate for completing the Cadence Program Management Training

2)Magnetics Design – Design of Magnetic Elements (Transformers, Inductors)

3)Power Conversion Design – I have been involved with the design of various linear and switching power topologies. These were intended for commercial, industrial, medical, military and space applications and used various construction techniques (hybrid, surface mount, through hole). They were driven from various sources (AC, DC, single and multi-phase) and range in power from a few Watts to a few K Watts.

4)Controller Design – I’ve used both integrated and discrete controllers in my designs.

5)Noise Mitigation – I have experience designing for low noise. This includes design of EMI filtering, a good understanding of parasitic elements and their effect on performance, best layout practices, and knowledge of testing per MIL-STD-461.

6)Design for Severe Environments – I have experience designing for Military Space and Down Hole Applications. This usually entails broad temperature range, broad pressure ranges, broad input ranges and electrical transients, as well as mechanical stress.

7)Design for Manufacture – I have used 6 Sigma statistical techniques applied to new design and existing designs to improve yields.

8)Design for Radiation Tolerance – I functioned as Radiation Officer. This involved design for radiation tolerance as well as creating, monitoring, and conducting element evaluation tests to insure product would meet specified requirements. I was involved in a number of JEDEC sessions and made minor contributions to Appendix G of MIL-PRF-38534 which details requirements for radiation assurance.

9) Troubleshooting – I’ve used Crane Troubleshooting Tools (i.e. pareto analysis, fishbone, statistical tools) and been a member of cross functional troubleshooting teams to solve complex problems. I’ve assisted in the training of production technicians for new product.

10)Qualification – I have been involved in the qualification of both products and processes. This includes preparation of test plans, writing of test reports, and hands on testing. Testing has included Electrical, Mechanical, Thermal, Process and Radiation.

11) Familiarity with Various Government and Industry Standards – This includes MIL-PRF-38534, MIL-PRF-19500, MIL-STD-461, MIL-STD 217, MIL-STD-883, and others.

12) Analysis – Worst Case and Radiation Tolerance Analysis, Thermal Analysis, Electrical Stress Analysis, MTBF Analysis, and FMECA analysis.

13) Design Tools Used – SPICE, MathCAD, RelCALC, EXCEL, AutoCAD, Word, Power Point, and others.

EXPERIENCE:

2006 – Nov, 2015 Crane Interpoint

Redmond, WA

Senior Engineer in the Space Products group.

Functioned as Radiation Officer for space product. Wrote Test Plans, Designed Fixtures, and Prepared Test Reports in compliance with MIL-PRF-38534, and MIL-STD-883 test requirements for both component level and top assembly tests. Assisted in the development of internal radiation procedures and guidelines. Interface with customers and regulatory agencies (DLA) regarding radiation requirements.

Performed various analyses in support of the SMRT standard DC-DC Converter Series (Worst Case Radiation Tolerance, FMEA, MTBF, Stress and Thermal).

Helped develop procedures and templates for standardization of Worst Case Tolerance Analyses. Implemented these to update and complete radiation analyses of various Interpoint hardened products.

Developed templates and checklists for review of BOM, Electrical and Thermal Stress Analyses, Schematics, And Worst Case Analyses

Conducted analyses and contributed to a redesign of existing custom product. Changes made were to address specific customer needs and concerns.

Sustaining Space Level Product. Support Qualification efforts of MFP point of load converters. Support redesign re-layout, and requalification efforts multiple series due to pad peel problems.
