Perform functional testing and validation for downhole tool electronics (heat/thermal test, ADC test, RSS monitor analysis, HI-POT test, and performance verification).
Troubleshoot high-current issues, short/open circuits, low-power boards, and intermittent failures to component level.
Conduct diagnostics using multimeter, oscilloscope, power analyzer, signal generator, and specialized test systems.
Replace and rework defective components (ICs, MOSFETs, regulators, op-amps, capacitors, resistors) in compliance with ESD and IPC standards.
Manage and clear aging WIP by prioritizing units, driving retest/repair actions, and closing cases to meet turnaround targets.
Perform M6 investigation for customer repair boards, including fault isolation, root-cause analysis, repair execution, and post-repair validation.
Prepare SOR/E4 technical reports and investigation summaries, communicating findings and actions to engineers and supervisors.
Support process/test improvements to reduce debug time and improve reliability performance.
Documented test results meticulously, preparing detailed reports for management review.
Collaborated with engineering teams to develop testing protocols for new products.
Monitored testing processes, adjusting parameters to optimise performance outcomes.
