IPC/WHMA-A-620 — Cable & Wire Harness Acceptability Training

Prime Alloys delivers IPC/WHMA-A-620 training focused on building, inspecting, and accepting cable and wire harness assemblies to consistent, auditable workmanship standards.

This training provides practical, image-based instruction on how to interpret acceptance criteria for soldered, crimped, welded, and mechanically secured wire terminations across Class 1, Class 2, and Class 3 products.

Foundations & Acceptance Criteria

• Purpose, scope, and product classification (Class 1, 2, 3)
• Acceptable conditions, process indicators, and defects
• Inspection methodology, lighting, magnification, and sampling
• Objective evidence, documentation, and disposition decisions

Wire Preparation & Handling

• Proper stripping, strand damage limits, birdcaging, twisting, and insulation damage
• Conductor deformation and preparation requirements
• Contamination control and ESD considerations

Soldered Terminations

• Tinning, solder connection requirements, and common anomalies
• Turrets, straight pins, bifurcated, slotted, pierced, hook, and cup terminals
• Insulation clearance, sleeving, and post-solder damage evaluation

Crimp Terminations

• Open-barrel, closed-barrel, machined contacts, and ferrules
• Conductor crimp, insulation support, bellmouth, brush, and cutoff criteria
• Crimp quality indicators and defect conditions

Splices, Ultrasonic Welding & IDC

• Soldered, crimped, and ultrasonic splices
• Insulation displacement connections (IDC) for flat and discrete cables
• Acceptability of mass termination and discrete wire terminations

Connectorization & Harness Assembly

• Connector mounting, strain relief, wire dress, sleeving, and boots
• Shield termination methods and grounding practices
• Routing, bend radius, securing, lacing, and breakout control

Inspection, Testing & Final Acceptance

• Electrical testing (continuity, shorts, DWV, IR)
• Mechanical testing (pull force, crimp height)
• Marking, labeling, measurement, and final inspection readiness

Who This Training Is For

• Cable and wire harness assemblers
• Inspectors and quality technicians
• Manufacturing, Quality and Process engineers

IPC/WHMA-A-620 Space & Military Addendum (620-S) Training

Prime Alloys delivers specialized training on the IPC/WHMA-A-620 Space and Military Addendum, focused on cable and wire harness assemblies designed to survive extreme vibration, thermal cycling, and mission-critical environments.

This training supplements IPC/WHMA-A-620 Class 3 requirements with space - and defense-specific workmanship, material controls, inspection rigor, and verification practices.

Training Outcome

Participants gain a Certified IPC Specialist (CIS) Certificate after successfully completing the module exams and a consistent, standards-based understanding of IPC/WHMA-A-620 requirements, improved inspection consistency, reduced rework, and increased audit readiness for cable and wire harness assemblies.
