How Stantek Manufactures Complex Wire Harnesses

  

 Stantek follows a controlled manufacturing process to produce complex wire harness assemblies according to customer drawings, specifications, bills of materials, and documented production requirements. Each stage focuses on accurate component integration, controlled assembly, electrical verification, and production traceability. 

• Step 1 – Project Review & Specification Interpretation

Stantek reviews customer drawings, specifications, bills of materials, routing requirements, and application documentation to establish the manufacturing requirements and support accurate interconnect integration of the complex wire harness assembly.

• Step 2 – Material & Component Verification

Required wires, connectors, terminals, shielding materials, protective sleeving, and other components are verified against customer specifications and bills of materials. Material and component traceability is maintained throughout production.

• Step 3 – Routing & Configuration

Wire routing, conductor configuration, component placement, signal management, shielding, and harness layout are performed according to customer-supplied drawings and specifications to support accurate assembly and system integration.

• Step 4 – Controlled Harness Assembly

Controlled wire processing, crimping, soldering, connector installation, strain relief, multi-level shielding, overmolding, and other specialized assembly operations are performed according to documented manufacturing requirements.

• Step 5 – Electrical Inspection & Testing

Electrical verification may include 100% continuity inspection, insulation resistance, impedance, functional testing, and signal integrity verification where required by customer specifications to confirm electrical integrity and performance.

• Step 6 – Mechanical & Environmental Verification

Where required, mechanical and environmental verification may include pull-force testing, dimensional inspection, thermal cycling, vibration testing, sealing verification, and other customer-specified requirements.

• Step 7 – Documentation & Traceability

Inspection records, test results, labeling, color-coding, revision information, material traceability, and production documentation are maintained to support consistent quality and complete manufacturing traceability.

• Step 8 – Final Quality Verification

Final inspection and quality verification are performed to confirm the completed complex wire harness meets applicable customer drawings, specifications, workmanship requirements, and documented acceptance criteria before shipment.
