2. New Product Introduction (NPI)

• Support product launches from prototype through full-scale production.
• Review Gerber files, BOMs, and assembly drawings to ensure manufacturability (DFM/DFA).
• Create process flows, work instructions, and control plans.
• Coordinate and execute pilot builds, process validation, and production readiness activities.

3. Equipment & Tooling Management

• Select, qualify, and validate SMT equipment (e.g., printers, SPI, pick-and-place, reflow ovens, AOI).
• Program and optimize production equipment, including:
  • SMT platforms (e.g., ASMPT, Panasonic, Fuji)
  • Wave soldering machines (e.g., Electrovert, SEHO, ERSA)
  • Conformal coating systems (e.g., PVA, Nordson)
• Establish and maintain preventive maintenance programs.
• Troubleshoot equipment and process-related issues to minimize downtime.

4. Quality & Continuous Improvement

• Analyze defects and lead corrective actions using methodologies such as 8D, RCA, and FMEA.
• Monitor and improve key performance indicators (KPIs), including FPY, OEE, yield, scrap, and cycle time.
• Implement mistake-proofing (poka-yoke) solutions and drive continuous improvement initiatives.

5. Documentation & Compliance

• Develop and maintain SOPs, process documentation, and engineering change records.
• Ensure compliance with industry standards, including IPC-A-610.
• Maintain accurate process data within ERP/MES systems.

6. Cross-Functional Collaboration
