IPC/WHMA-A-620C - Requirements & Acceptance For Cable & Wire Harness Assembly

 

IPC/WHMA-A-620C 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 also available for hands-on assembly of a wiring harness with a mix of crimped terminations.

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