Descripción del empleo

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 instructions and standard operating procedures
• Establish and validate inspection criteria and defect thresholds aligned with IPC standards.
• Drive continuous improvement for defect reduction, yield improvement, and process stability.
• Collaborate with manufacturing, quality, maintenance, and suppliers to ensure process alignment, equipment uptime, and defect containment.
