  Engineering tool owner responsible for various manufacturing processes and metrology tools at a flexible PCB shop, including electrolytic copper, nickel, and gold pattern plating lines; XRF and drop gauge tools; and wet processing area DI water supply. Key achievements include: • Developed a computer program in LabView to control DC power supplies for electroplating lines, with an easy-to-use HMI for plating recipe entry, auto-generation of run logs, and current/voltage trace output; program was major improvement over existing process that required manual run logging and rectifier configuration. • Installed and qualified a vacuum-chuck stage for an XRF spectrometer using statistical tests, correlation studies, and gage R&R’s; vacuum chuck reduced gage variation by over 50% and cut setup time 6-fold. • Upgraded shop DI water supply system by purchasing and installing PLC with web-based HMI that enabled 24-7 remote water quality datalogging with programmed alarms. • Increased flex PCB electroplating process yields by implementing process control limits, tracking Cpk, and performing process characterization studies using design of experiments (DOE) principles. • Supported factory throughput improvement efforts by designing larger plating tank fixtures using CAD software and qualifying a larger-volume copper plating line, work that enabled larger workpiece sizes. • Standardized operations and best practices on the floor of a plating shop by writing SOPs and related training materials.

  • Jul 2018 - Oct 2019

  Served as the main process engineer on a NextFlex-funded collaborative project between MicroConnex and the University of Washington that developed a hybrid process for manufacturing sub-50-um space and trace interconnects on flex using roll-to-roll seed layer printing and subsequent electrodeposition. At the end of the project, a provisional patent application was filed for the hybrid print-plate process. Key tasks and achievements: • Characterized the flexographic printing parameter space for producing high-resolution metal interconnects on flex using nanoparticle-based inks. • Developed custom electrolyte chemistry designed for copper electrodeposition onto fragile high-resistivity seed layers. • Used COMSOL finite element software to model current distribution when plating onto high-resistance electrodes. • Performed optical inspection and trace width measurements of printed-and-plated circuits using ImageJ, and analyzed this as well as electrical test data using JMP. • Used ImageJ’s Java scripting language to write code to semi-automate the optical inspection and dimensioning process to facilitate analysis of large experimental datasets. • Wrote quarterly and final reports and prepared and presented webinars to the NextFlex community Show less
