Job Details Job Location: Fort Worth, TX 76177 Position Type: Full Time Education Level: Graduate Degree Travel Percentage: Up to 10% Job Shift: Day Job Category: Manufacturing Mainboard Repair Engineer Location: Fort Worth Alliance, TX Department: Engineering Reports To: Senior Engineering Leader Employment Type: Full-Time Position Summary A Motherboard Repair and Failure Analysis Engineer are highly specialized technical experts responsible for investigating, diagnosing, repairing, and analyzing issues within motherboard circuits and other related hardware. They typically possess a deeper technical understanding compared to a technician and are often involved in higher-level fault analysis, testing, and design feedback to improve product reliability and quality. Key Responsibilities Essential Duties and Responsibilities include the following. Other duties not listed may be assigned. (90%) Advanced Diagnostics: Use complex diagnostic tools and techniques, such as circuit simulation and PCB layout analysis, to pinpoint failures. 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. Knowledge of BIOS/EFI flashing, BGA rework, and firmware interfaces. 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: Multimeters, oscilloscopes, signal analyzers, spectrum analyzers. POST (Power-On Self-Test) cards for BIOS/UEFI troubleshooting. Thermal cameras and X-ray systems for detecting trace breaks or solder voids. For Repair: BGA rework stations for replacing or reflowing chip components. Soldering stations (hot air rework stations, soldering irons). Chip programmers (e.g., to reprogram BIOS or flash chips). For Analysis: Software tools such as MATLAB/Simulink, Proteus, and Altium for circuit and PCB design simulations. Cross-section analysis and environmental stress test equipment. Qualifications Qualifications Educational Background: Bachelor’s degree in Electronics Engineering, Computer Engineering, or equivalent fields. Specialization or training in PCB design and hardware debugging. Certifications (Optional but valuable): IPC 7711/7721 Certification for PCB soldering IPC-A-610 Certification for PCB assembly and workmanship standards. CompTIA A+ Certification (basic PC knowledge). Certified Electronics Technician (CET) Credential. Advanced Certifications in Signal Integrity or Power Integrity analysis. Challenges in the Role Working with advanced multilayer PCBs with intricate traces. Diagnosing intermittent issues, which may require prolonged testing under various conditions to recreate. Keeping skills updated with new technologies like advanced DDR memory, PCIe lanes, and power sequencing systems. Working Conditions Must be able to tolerate moderate to high noise levels in a warehouse environment. Office and outside environmental conditions found in the warehouse, hot in the summer, cold in the winter. Individuals may need to walk for an extensive period of time while working and walking the facilities; to reach over shoulder heights; bend or stoop below the waist; repetitive wrist, hand, or finger movement. Must be able to lift 25 pounds. Benefits Health, dental, and vision insurance. 401(k) with company match. Paid time off and company holidays. Professional development and training opportunities.
