In a high-volume contract-manufacturing environment, the product changes but the discipline doesn't: every process has to be fast, in control, and documented well enough that quality doesn't depend on any one shift. Optical assembly adds precision and cleanliness constraints on top of standard SMT, so there's little room for a process that drifts.
My role was process engineering on optical transceiver and module lines — keeping running processes capable and improving the metrics that drive cost and quality at scale.
Owned and optimized process steps across print, place, reflow, and precision optical assembly — profiling, setting process windows, and qualifying changes before they reached the line.
Targeted cycle time, first-pass yield, and scrap on running lines, with the SOPs and controls to make sure improvements held over time rather than eroding back.
Led structured investigations on recurring defects, isolating the dominant causes and closing them out with process and documentation changes.
Volume rewards rigor. The gains came from treating each process step as something measurable and improvable — and from building the controls that keep a tuned process tuned after the project closes.
