Responsible for developing, installing, validating, and sustaining selective soldering processes for power electronics PCBAs. This is a hands-on manufacturing engineering role focused on process robustness, defect prevention, and validation through AOI/AXI inspection and cross-section analysis. The position includes equipment installation, commissioning, safety compliance, and quality documentation ownership.
- Develop, optimize, and maintain selective soldering processes (preferably using Ersa equipment) to ensure consistent solder joint quality and high production yield.
- Lead equipment installation and commissioning of selective soldering lines, including setup, calibration, qualification, and ramp-up to production.
- Define and control critical process parameters: fluxing, preheating, solder pot temperature, nitrogen usage, nozzle selection, cycle times, and maintenance intervals.
- Ensure compliance with manufacturing safety standards (including thermal, chemical, and ESD controls) during installation, operation, and maintenance.




- Analyze and resolve soldering defects such as bridging, insufficient fill, icicles, voids, non-wetting, dewetting, driving root cause and permanent corrective actions.
- Perform hands-on cross-sectioning and solder joint analysis, including evaluation of intermetallic layers, wetting behavior, and internal defects.
- Define and execute cutting strategies for NPI, ensuring representative sampling of critical joints and interfaces.
- Utilize and interpret AOI and AXI inspection systems to validate soldering quality and correlate inspection results with physical analysis.
- Plan and execute process validation activities (DOE, process window definition, capability studies, PPAP support when applicable).
- Own and maintain quality and manufacturing documentation, including:
- PFMA / PFMEA (process risk analysis specific to soldering)
- DCP (Process Control Documents)
- Control Plans (inspection points, reaction plans, limits)
- Work inst
