Job description

• Responsible for performing component-level troubleshooting, root-cause failure analysis, and high-precision soldering repairs on defective PCBAs.
• Collaborates closely with engineering and quality teams to log failure data, address production fallout, and drive continuous improvement in manufacturing yield.

Key Responsibilities

• Perform component-level troubleshooting on defective PCBAs and functional test failures generated from the production floor .
• Interpret electrical schematics, circuit diagrams, layout files, and engineering documents to isolate root causes of circuit abnormalities or component failures.
• Utilize diagnostic instruments such as digital oscilloscopes, multimeters, DC power supplies, logic analyzers, and specialized test software to trace signals and verify board behavior.
• Perform high-precision manual soldering, desoldering, and component replacement (including SMT parts, IC chips, passives, and connectors) in compliance with IPC standards.
• Maintain and update the production line failure logging system; systematically record defect codes, failed components, root causes, and repair actions taken.
• Collaborate closely with Test Engineers and Quality Engineers to provide real-time feedback on recurring defects, component issues, or design anomalies to drive continuous yield improvement.
• Partner with the Test Technician to use verified reference units ("Golden Boards") to isolate whether a failure stems from the product itself or an anomaly in the testing fixture.
• Provide active technical assistance to line operators and testing teams to address sudden spikes in product fallout or test sequence failures.
• Maintain a clean, organized, and safe ESD-safe environment at the debugging workstation; strictly adhere to company environmental and safety guidelines.

Qualifications Required

• Certificate/Diploma in Engineering (Electronics, Mechatronics, or related field).
• 2+ years of experience in PCBA Debugging.
• Familiarity with automation equipment and PCB testing processes.

Preferred Skills

• Strong proficiency in component-level PCBA troubleshooting, signal tracing, and IPC-compliant SMT soldering/rework.
• Ability to read and interpret complex schematics, PCBA layouts, and technical drawings effortlessly.
• Experience using failure logging databases to capture root causes and track failure trends.
• Familiarity with PCBA manufacturing, SMT lines, and functional testing environments.

Personal Qualities

• Detail-oriented with strong problem-solving skills.
• Ability to work under tight deadlines.
• Team player with proactive communication.
