o Bond pull / shear

 Analyze excursions and process drifts; propose corrective actions and process

improvements. Support yield reviews and process health reviews jointly with Quality and

Operations.

3.3 Quality & Compliance Support

 Ensure process definitions are compliant with:

o MIL-STD-750

o MIL-PRF-19500

o JEDEC standards

o Customer and space/aerospace flow-downs

 Compile technical process evidence for:

o First lots

o Process qualification

o Customer reviews

 Support root cause analysis and CAPA implementation for process-related non-

conformances.

 Ensure all process, material, or recipe changes are properly documented and

submitted through formal change control.

3.4 Equipment & Materials Engineering

 Define:

o Equipment recipes

o Calibration requirements

o Preventive maintenance plans

 Support qualification and acceptance of:

o New tools

o Process automation solutions

 Evaluate and technically qualify new materials for thermal, mechanical, and

reliability compatibility.

3.5 Data, MES & Traceability Integration

 Ensure complete and accurate process data collection via equipment interfaces

 Support integration of process data into traceability systems, ensuring:

o Parameter traceability

o Configuration linkage

o Lot / serial integrity

 Analyze defect, yield, and trend data using statistical tools (Minitab, JMP,

Python, Excel).

3.6 Cross-Functional Collaboration & Training

 Work closely with:

o Design (DFM / DFR feedback)

o Quality Engineering

o Production

 Train operators and technicians on:

o Process setup

o Handling

o Troubleshooting

 Actively contribute to Lean / Kaizen / 5S / improvement initiatives.4. Qualifications
