IPC/WHMA-A-620D
Requirements and Acceptance for Cable and Wire Harness Assemblies

IPC/WHMA-A-620D is a compendium of requirements for assembly of cable and harness assemblies. This 4-day lecture certification class provides a review of requirements for assembly of Class 1, 2, and 3 products. It is modularized to provide flexibility in user requirements. A CIS exam is included for each module.

An optional, 1-day lab is available for hands-on assembly of a wiring harness with a mix of crimped terminations.

Upon completing the course, the CIS receives an IPC-620D certificate identifying each module successfully completed. The certificate is valid for 24 months. Recertification includes review of the IPC-620D document and written exams.

IPC-620D modules are summarized as follows:

Module 1 - Introduction to CIS P & P, General/Applicable Documents, Assemblies and Wires (Mandatory)

Module 2 - Lecture - Crimp Terminations and Insulation Displacement Connection (Optional)

Includes a review of design features of Stamped and Formed Open and Closed Barrel terminations, machined contacts, flat cable and discrete wire terminations.

Module 3 - Lecture - Soldered Terminations (Optional)

Addresses materials, cleanliness, lead prep and solder requirements for common terminals.

Module 4 - Lecture - Connectorization, Over-Molding and Potting (Optional)

Reviews hardware mounting, strain relief, sleeving, and damage to connector hardware.

Module 5 - Lecture - Splices (Optional)

Specifies assembly, solder criteria, and splicing detail for common splices.

Module 6 - Lecture - Marking, Labelling, Securing (Optional)

Summarizes marking/labelling and lacing requirements for coaxial and biaxial cable assemblies.

Module 7 - Lecture - Coaxial and Biaxial Cable Assemblies (Optional)

Stripping, crimping and soldering of axial and biaxial shielded wire.

Module 8 - Lecture - Solderless Wrap (Optional)

Specifies criteria for turn/turn spacing, end tails and raised turns for solderless wrap.

A 10-30 Question Open Book Exam follows each class lecture. The Minimum passing grade is 70 for each. Hands-On Modules are optional.
