• Develop & validate thermal profiles for recent & existing PCB assemblies.
• Stencil Design & Validation.
• Conduct DOE & Process validation for new products and materials.
• Setup , Monitor & Control critical reflow parameters (Zone temp., Conveyor Speed, Soak time, Peak temp.)
• New Model Readiness
• Develop & Maintain Process documentation, WIs & SOPs (SPP, SPI & Reflow)
• All new models trail pre-readiness (EVT/ DVT / PVT) , new model trail activities including trial builds & process validation.
• Partner with NPI, TDG to ensure DFMEA and PFMEA of SPP,SPI & Reflow (related to soldering & thermal constraints )
• Ensure proper solder paste reflow per component and PCB design requirements
• Ensure smooth technology transfer from development to production.
• Own ramp-up metrics:



yield learning curve, cycle time, scrap reduction.
• Quality Excellence
• Accountable for first pass yield, final yield and field reliability.
• Lead root cause analysis for yield excursions using SPI data , SPC charts , Yield Trends ,FMEA, DOE and failure analysis.
• Monitor production yield , defect rates , cycle time and implement corrective / preventive actions.
• Collaborate with Quality , NPI & Customer to resolve manufacturing & Quality issues such as tombstoning , voiding , bridging , cold joints and solder balls
• Partner with Quality team to address customer returns, audits and escalations.
• Monitor Process parameters ( temp. Zones , conveyor speedsoak time etc )
• Analyze & control print defects ( Insufficient / excess paste , smearing , bridging , skips , misalignment)
• Analyze soldering defects ( tombstoning , voids , cold joints , bridging etc ) and implement corrective actions
• Operational Excellence & Cost Optimization
• Own cost of ownership and productivity improvement initiatives.
• Drive Cycle time and line balancing improvements.
• Lead process development , validation & continuous improvement initiatives ( Kaizen , Poka yoke , Lean Manufacturing )




• To ensure Proper line setup , programming , Program version management ( SPP , SPI & Reflow )
• To ensure compliance with ESD , Safety& IPC standards.
• Analyze process data , SPC reports to identify trends & improvement opportunities.
• Customer & Stakeholder Engagement
