Key Responsibilities

• Lead SMT process development, optimization, and qualification for SOM and complex PCBA assemblies.
• Plan, execute, and interpret Design of Experiments (DOE) to establish robust process windows.
• Drive NPI builds from prototype to mass production, ensuring full process readiness and documentation compliance.
• Define, verify, and control critical process parameters such as stencil design, paste selection, and reflow profile optimization.
• Perform and analyze Shadow Moiré testing to assess package warpage and thermal deformation impact on assembly yield.
• Coordinate with design, material, and quality teams to troubleshoot and implement process improvements.
• Conduct DFM/DFT reviews, void reduction trials, and co-planarity control for advanced packaging.
• Maintain accurate PFMEA, Control Plan, Process Flow, and Work Instruction documentation.
• Evaluate and qualify materials, solder pastes, fluxes, and SMT equipment in accordance with IPC/JEDEC standards.
• Ensure all assigned activities are completed independently, responsibly, and within project timelines.

Requirements

• Bachelor’s Degree in Electronics, Manufacturing, or Mechanical Engineering (or equivalent).
• Minimum 2 years hands-on experience in SMT / PCBA / SOM process development or NPI engineering.
• In-depth knowledge of SMT process fundamentals: reflow profiling, stencil design, solder paste rheology, and AOI/SPC control.
• Experience in Shadow Moiré warpage analysis and interpreting thermal co-planarity results.
• Skilled in DOE, SPC, CPK, and structured problem-solving methodologies (DMAIC, 5-Why, Fishbone).
• Familiar with IPC-A-610, J-STD-001, and JEDEC standards.
• Excellent analytical, documentation, and communication skills.
• Independent, proactive, and responsible in executing engineering tasks with minimal supervision.
