Role Overview
A TCB Design Engineer is responsible for designing, developing, and optimizing the TCB modules subsystem used in Thermo-Compression Bonding (TCB) equipment for advanced semiconductor packaging. This role is critical for ensuring precise, uniform, and rapid thermal control during Chip-to-Wafer or Chip-to-Substrate bonding, directly impacting process reliability, yield, and throughput.
Key Responsibilities
Must-have:
- Design & Development
- Design innovative TCB modules assemblies for Chip-to-Wafer or Chip-to-Substrate bonding.
- Responsible for 3D design and 2D drawings, BOM management, FMEA, error budgeting, Design for Manufacturability and Assembly (DFMA).
- Planning, Scheduling and Costing of Machines Modules.
- Prototyping & Testing
- Oversee fabrication of prototype modules and their integration with TCB platforms.
- Analyze test results, identify design improvements, and troubleshoot failures related to temperature non-uniformity, inefficiency, or material degradation.
- Process & Manufacturing Support
- Collaborate with Electrical, Vision and Software Engineers for the machine integration.
- Collaborate with process team to improve the bonding machine (e.g., bonder heads, stages, temperature/power controls)
- Collaborate with manufacturing engineers to ensure DFMA and safe, robust assembly of module systems.
- Support transfer of new heater designs from R&D to production, including documentation, BOM, and assembly guides.
- Compliance & Documentation
- Document all designs, simulations, and test results according to quality management and IP standards.
- Remain updated on relevant industry standards for environment, health and safety, contamination control, and semiconductor packaging equipment.
Good-to-have:
- Thermal & Mechanical Analysis
- Perform thermal simulations (CFD, FEA) to optimize heating/cooling profiles and minimize thermal gradients across the TCB bondhead/ bondstage.
- Design and validate cooling channels (e.g., for air or liquid) inside the bondhead/ bondstage to achieve rapid cooling and enhance temperature uniformity.
- Ensure safe and stable mounting of the heater assembly for micron-level Z positioning and planarity during operation.
Required Skills and Qualifications
- Bachelor’s or Master’s degree in Materials Science, Mechanical Engineering, Electrical Engineering, or a related field.
- Minimum 2–5 years of hands-on experience in design and development of equipment's or semiconductor packaging or advanced interconnect processes.
- 3D/2D CAD knowledge, with experience in CREO Parametric preferred. Exposure to CREO Windchill PLM system is a plus.
- Experience with TCB or Laser Assisted bonding technologies is highly preferred.
- Familiarity with bonding equipment and analytical tools (X-ray, SAM, OM, etc.)
- Excellent trouble-shooting, risk analysis, FMEA, and statistical analysis (JMP, Minitab).
- Knowledge of bonding process and materials behaviour under thermal/mechanical stress (e.g., CTE mismatch, flux residue, underfill cure).
- Good communication and cross-functional collaboration skills.
- Experience in design and development of Modules like Bond head, Bond Stage, Thin Die Handling, Large Die Handling, Clean Room Class 100 Systems, Plasma Modules, N2 System is a plus. Experience with thermal system/component design (heaters, sensors, thermal interfaces), including hands-on and simulation skills.
- Experience on HBM, COWOS, 2.5D, Fluxless Bonding is a definite plus.
