Process Engineering

Role Overview: SME

• Solder Paste Printer & Reflow Soldering is responsible for overseeing, optimizing & continuously improving processes to ensure on-time manufacturing with high quality of all ISP Products. The role is accountable for process yield, reliability, cost saving while building strong cross functional alignment with NPI & TD, equipment, quality and customer teams.

Responsibilities

Technology & Process Setup Manage & Optimization of SMT Production Processes of Solder Paste Printing , Inspection & Reflow. Define and maintain all process windows, control plans & CTQ across all products of SPP , SPI & Reflow. Setup, Operate, Programming, Optimizing SPP & Reflow Soldering machines. Setup & Validation of Stencils, Squeegees, Solder Paste types & Printing parameters.

Develop & validate thermal profiles for new & 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 Serve as a technical team member for customers on PCBA Soldering process topics. Will be technical team member for customer reviews, technology discussions and risk mitigation plans. Key Deliverables & KPI First Pass Yield Yield and Reliability Performance Productivity Improvement Cost Optimization Customer satisfaction and audit outcomes.

Education
