About the role:

The Wire Bond Process Development Staff Engineer is responsible for leading the design, development, and industrialization of advanced wire bonding processes for semiconductor packages. This role involves working with cross-functional teams to ensure robust, cost-effective, and scalable solutions that support New Product Introductions (NPIs), technology innovation, and high-volume manufacturing.

What you will do:

• Lead process development and qualification of wire bonding for packages such as QFN, DFN, BGA, HVQFN, SIP, and power devices.
• Drive innovation in fine-pitch, low-loop, multi-tier bonding, and Cu, Ag, Au wire bonding technologies.
• Define bonding parameters, wire/capillary specs, loop profiles, and pad layout guidelines for optimal performance and reliability.
• Conduct Design of Experiments (DOE) and failure analysis to fine-tune bonding processes for electrical, mechanical, and thermal robustness.
• Evaluate and select bonding equipment and tools (e.g., K&S, ASM, Hesse) to support new technology and process scaling.
• Lead material characterization, such as wire-paddle interface, IMC formation, oxidation, and corrosion behavior.
• Collaborate with Package Design, NPI, Reliability, and Operations teams to ensure process and product alignment.
• Solve complex yield and quality issues, providing in-depth root cause analysis and implementing long-term corrective actions.
• Develop documentation and standards including process flows, control plans, FMEAs, and technical specifications.
• Support technology transfer and provide leadership in process ramp-up at internal sites or OSAT partners.

What you will need:

• Bachelor’s or Master’s Degree in Electronics, Materials Science, Mechanical Engineering, or a related field.
• Minimum 8+ years of experience in semiconductor assembly process development, specifically wire bonding.
• Strong hands-on experience with wire bonding tools, materials, and defect analysis.
• Solid understanding of bonding failure modes, such as NSOL, heel crack, pad lift, wire sweep, and corrosion.
• Proficient in statistical tools (JMP, Minitab), SPC, and problem-solving methodologies (8D, DMAIC).
• Strong technical writing, communication, and cross-functional collaboration skills.
