Job Description

Hands-on technician role performing board-level diagnostics, rework, repair, and verification on PCBs, load boards, interface cards, and modules supporting semiconductor test and manufacturing. Scope includes fault isolation, component-level replacement (SMD/BGA/QFN/through-hole), micro-soldering, reflow profiling, X-ray verification, and conformal coating/cleaning. Partners with Test Engineering, FA/Quality, and Production to restore functionality quickly and prevent repeats.

• Triage incoming boards; document failure symptoms, history, and disposition in CMMS/repair tracker.
• Perform component-level fault isolation using schematics, netlists, continuity, and signal tracing.
• Execute soldering/rework: BGA, QFN, LGA, fine-pitch, through-hole; micro-soldering under microscope.
• Set & verify reflow profiles; manage BGA reballing; validate with X-ray/AOI as needed.
• Use DMM, oscilloscope, LCR, bench power, hot air, preheater, rework station, microscope.
• Inspect & clean assemblies; manage flux/cleaners; re-apply conformal coating per spec.
• Handle ESD controls, correct moisture sensitivity (MSL/bake), LOTO on powered jigs/fixtures.
• Update ECO notes, work instructions (WIs), and repair records; ensure full traceability.
• Collaborate on design-for-repairability feedback; highlight weak points (pads, vias, thermals).
• Support load-board/contact hardware care (socket/lid threads, pins, receptacles, pogo pins).

• Diploma/Associate’s in ECE/EE/Mechatronics (or equiv. experience); 2+ years board-level repair in electronics manufacturing/service (preferably test hardware/PCBA).
• Proficiency with soldering stations, hot air, BGA rework systems, microscopes, and metrology.
• Strong ESD, MSL, and safe handling of lead-free and chemicals (flux/cleaners).
• Able to read schematics, BOMs, ECAD outputs (Gerbers, netlists).
