- Control furnace temperature, heating profiles, alloy additions, homogenization, holding, and casting parameters.
- Operate OES (Optical Emission Spectrometer) and interpret chemical composition results.
- Develop and control melting and master-alloy addition processes for SAC305, SAC0307, and other solder alloys.
- Control Tin (Sn) melting and alloying processes, including impurity control and dross management.
- Investigate and correct off-specification batches, composition variation, segregation, and contamination.
- Identify and resolve casting defects such as porosity, shrinkage, dross entrapment, and cracking.
- Maintain QC checklists, batch records, traceability documents, and Certificate of Analysis (CoA).
- Monitor impurity elements including Pb, Bi, Sb, Zn, Fe, Al, As, and Cd.
- Support alloy development, process trials, and continuous improvement.
- Coordinate with raw-material and master-alloy suppliers regarding material quality.




- Train furnace operators on melting, casting, SOPs, and safety procedures.
- Maintain records related to melting point/DSC, microstructure, and mechanical testing.
- Ensure compliance with applicable quality and environmental standards.
