IPC 620

 

IPC/WHMA-A-620 is the first industry consensus standard for cable and wire harness fabrication and installation. Classes of products are defined and include criteria for Target, Acceptable, Process Indicator and Defect conditions. These criteria are supported by over 500 full-colour illustrations. It is a theory only course designed to provide students with the ability to understand and utilise the accept / reject criteria for a variety of subjects.

Students who successfully achieve 70% or greater in the exams will receive a recognised IPC certificate which is valid for two years. Certification demonstrates commitment to customer requirements and greatly facilitates certification to ISO-9001 or other quality assurance initiatives.

 There is 1 mandatory module and 7 optional modules. The optional modules can be chosen depending on company requirements and can be added in if necessary during the 2 year certification period, although the certification on all modules expires at the same time (2 years after the date at which the mandatory modules were completed).

The following section provides a breakdown of the content of each of the modules. A multiple choice exam needs to be successfully completed at the end of each module to allow inspection of these subjects.
