- Analyze power delivery, thermal dynamics, and electrical signal integrity across multilayer PCBs.
- Troubleshoot performance issues with CPU, GPU, RAM, and chipset communication.
- Failure Analysis:
- Determine root causes motherboard failures, such as hardware defects, environmental damage, design flaws, or manufacturing issues.
- Perform post-mortem analysis using tools like X-ray inspection, electron microscopy, or infrared thermography.
- Component-Level Repairs:
- Identify and repair or replace defective components like capacitors, transistors, microcontrollers, or BGA (ball grid array)-mounted chips.
- Rework layered wiring, repair PCB traces, and perform micro-soldering work using advanced equipment.
- Testing and Validation:
- Execute rigorous testing of repaired motherboards under various operating conditions, including thermal stress, load testing, and PSU variations.
- Ensure adherence to quality benchmarks during testing and monitor for early fault indicators.
- Collaboration with Design Teams:
- Provide insights and feedback to R&D, quality assurance, and manufacturing teams for future iterations of the motherboard design.
- Collaborate with cross-functional teams to identify and minimize hardware vulnerabilities and enhance product performance.
- Document and Report:
- Generate detailed reports on identified issues, root cause analysis, and the corrective steps implemented.
- Maintain thorough records of common repair issues and propose design improvements to improve reliability.
- Research and Development:
- Participate in testing new designs and building prototypes.
- Suggest changes to enhance motherboard architecture based on analysis of prior failures.
- Customer Support:
- Offer technical support to clients or end-users, ensuring a clear understanding of failure causes and the rationale for repairs. When required, work assignments can change based on project needs like inspection, solder, testing, and data input.
- Other duties as assigned.
Key Skills and Expertise
- Technical Skills:
- In-depth understanding of PCB design, electronics, and microprocessor architecture.
- Proficiency in circuit debugging methodologies for analog, digital, and mixed-signal circuits.

- Diagnostic Tools:
- Experience with diagnostic tools like logic analyzers, digital oscilloscopes, vector network analyzers, X-ray/thermal inspection tools, and simulation software (e.g., OrCAD, Altium Designer).
- Use of simulation software to validate electrical designs and predict points of failure.
- Soldering and Rework:
- Expertise in rebelling, reflow soldering, and soldering/desoldering small SMD components and chips such as ICs, FPGAs, or diodes.
- Troubleshooting Expertise:
- Ability to troubleshoot issues across multi-layer PCBs including damaged traces, cold solder joints, or short circuits.
- Strong analytical skills for interpreting diagnostic test outputs.
- Failure Mode Effect Analysis (FMEA):
- Ability to carry out FMEA processes to prevent recurring issues and improve reliability during the motherboard production cycle.
- Collaboration and Communication:
- Strong communication skills to interact with internal design teams, manufacturing engineers, and customers.
- Proficiency in preparing technical failure reports and presenting findings clearly.
Examples of Tools and Equipment Used
- For Diagnosis:
