Role Summary

Ecopmin Technologies' Solder Division is looking for a Metallurgical Engineer to own alloy formulation, melting process control, composition verification, and quality assurance for our lead-free solder product range, including SAC305, SAC0307, and related Sn-Ag-Cu alloys, across bar, wire, and paste formats.

The role will ensure that every batch meets IPC J-STD-006 / ISO 9453 composition and impurity specifications before release to customers.

Key Responsibilities
- Develop and control alloy melting, master-alloy addition, and homogenization processes for SAC305, SAC0307, and other solder alloys.
- Set and monitor furnace temperature profiles at each stage, including melting, alloying, homogenization, and casting.
- Operate and interpret results from OES (Optical Emission Spectrometer) for composition verification.
- Investigate and correct off-spec batches, including composition drift, segregation, and impurity contamination.
- Conduct root-cause analysis for casting defects such as porosity, shrinkage cavities, dross entrapment, and cracking.




- Establish and maintain QC checklists, batch travelers, and Certificate of Analysis (CoA) documentation.
- Monitor and control impurity elements including Pb, Bi, Sb, Zn, Fe, Al, As, and Cd as per IPC J-STD-006B limits.
- Optimize alloy yield by minimizing dross loss, metal wastage, and rework.
- Support recent alloy development and trials for customer-specific grades.
- Coordinate with raw material and master-alloy suppliers regarding incoming material quality.
- Train furnace operators on melting/casting SOPs and safety procedures.
- Maintain melting point (DSC), microstructure, and mechanical property test records.
- Ensure compliance with RoHS, IPC J-STD-006, and ISO 9001 quality systems.

Required Skills & Competencies
- Strong understanding of binary and ternary alloy phase diagrams, specifically the Sn-Ag-Cu system.
- Hands-on experience with induction or resistance melting furnaces.
- Proficiency in OES/
