• Component Placement
• Reflow Soldering
• Automated Optical Inspection (AOI)
• Solder Paste Inspection (SPI)
• Selective Soldering
• Conformal Coating (where required)
• Drive process improvements focused on quality, capacity, automation, and cost reduction.
• Implement Lean Manufacturing, Six Sigma, and Design for Manufacturing/Assembly (DFM/DFA) principles.

New Product Introduction (NPI)

• Provide manufacturing expertise during design reviews and product development.
• Partner with Design Engineering, Applications Engineering, and Operations teams to ensure manufacturability.
• Develop process validation plans and qualification criteria for new products.
• Support prototype builds, pilot runs, and production ramp activities.

Global Operations Collaboration

• Partner closely with AIS's Taiwan assembly operations to establish common process standards and best practices.
• Drive cross-site process harmonization and knowledge transfer.
• Participate in global manufacturing reviews and continuous improvement initiatives.
• Support benchmarking and replication of successful process improvements across AIS assembly locations.

Equipment & Technology Leadership

• Define equipment requirements and process technology roadmaps.
• Support selection, installation, qualification, and optimization of SMT manufacturing equipment.
• Collaborate with Maintenance and Equipment Engineering teams to maximize uptime and process capability.
• Evaluate emerging SMT technologies and automation opportunities.

Quality & Compliance

• Ensure compliance with IPC standards and customer-specific manufacturing requirements.
• Support customer audits, internal audits, and corrective action activities.
• Lead PFMEA, Control Plan, and process validation activities.
• Drive a culture of operational excellence and continuous quality improvement.

Leadership & Mentoring

• Provide technical leadership to manufacturing engineers, technicians, and production personnel.
• Develop standardized work instructions, process documentation, and training materials.
• Mentor junior engineers and help build AIS's long-term manufacturing capabilities.
