Manufacturing Process Engineer 1997-Present
·
Completed process capability reviews on automated surface mount line including solder paste printer, pick & place equipment, and reflow oven which led to a Defects per Million Opportunities (DPMO) reduction from 3000 to 500.·
Supervised the evaluation, cost justification and installation of $900,000 of printed circuit board assembly equipment for both surface mount and through-hole assembly processes.·
Improved assembly process control by implementing routine thermal profiling of reflow, wave solder, and rework processes, which resulted in a 40% reduction in touch-up work.·
Responsible for plant layout of entire production area into manufacturing cells, improving product visibility, increasing process cycle time by 60%, and reducing work-in-process by 33%.·
Provide Design for Manufacturability (DFM) recommendations to customers’ PWB designs resulting in assembly cost and quality improvements.·
Facilitated 8 person surface mount continuous improvement team responsible for identifying critical process improvements through pareto and DPMO metrics·
Implemented surface mount assembly defect recording, tracking, and feedback system using SPC techniques, resulting in an increase in first pass SMT yield from 66% to 90%.·
Conducted process qualification for Ball Grid Array (BGA) assembly process, which to date has achieved a first pass yield rate greater than 99%.
