Core Responsibilities

Primary Functions

Interpret and follow detailed instructions from complex blueprints, wiring diagrams, schematics, and engineering assembly procedures to build wire harnesses.
Perform intricate wire preparation tasks, including precise cutting to length, stripping of insulation, and tinning of wire ends using both hand tools and automated equipment.
Route, group, and secure wires and cables into intricate formations on harness layout boards, ensuring compliance with specified layouts and standards.
Execute precise crimping of terminals, pins, and contacts onto various wire gauges using manual hand crimpers, pneumatic tools, and semi-automated crimping presses.
Apply hand soldering and de-soldering techniques to attach wires to connectors, circuit boards, and other components, adhering to IPC or equivalent quality standards.
Install and secure protective coverings such as heat shrink tubing, convoluted tubing (loom), braided sleeving, and PVC tape to protect and bundle wires.
Assemble and install a variety of connectors, backshells, clamps, and other hardware onto the harness, ensuring proper orientation and torque.
Conduct first-piece and in-process visual inspections on assemblies to verify conformance to specifications and identify any potential defects or errors.
Perform basic electrical continuity, insulation resistance, and component placement checks using multimeters, DMMs, and custom go/no-go test fixtures.
Operate various wire processing machinery, including automatic wire cutters, strippers, twisters, and labeling machines, with a focus on safety and precision.
Utilize precision measuring instruments like calipers, rulers, and pin gauges to verify wire lengths, component placement, and overall assembly dimensions.
Identify, tag, and segregate non-conforming parts or assemblies, and clearly communicate any build or material issues to team leads or supervisors.
Apply identification markers, labels, and tags to wires and harnesses according to blueprint specifications for traceability and installation purposes.
Pot, mold, or encapsulate connectors and splices using specified compounds to provide strain relief and environmental protection.

Secondary Functions

Maintain accurate and detailed production records, including work order documentation, traveler sheets, and logs for material traceability and labor reporting.
Adhere strictly to all company safety guidelines, including the proper use of personal protective equipment (PPE) and maintaining a safe work environment.
Contribute to maintaining a clean and organized workstation and production area by following 5S principles (Sort, Set in Order, Shine, Standardize, Sustain).
Assist in the training and mentoring of newer or less experienced operators on standard assembly processes and quality requirements.
Collaborate with manufacturing engineers and quality technicians to troubleshoot assembly problems, provide feedback on documentation, and support root cause analysis.
Manage component and consumable inventory at the workstation, proactively communicating potential shortages to material handlers or supervisors to avoid production delays.
Participate actively in continuous improvement (Kaizen) events and lean manufacturing initiatives aimed at enhancing production efficiency, quality, and safety.
