This 4-day (including hands-on exercises) “IPC/WHMA-A-620, Requirements and Acceptance for Cable and Wire Harness Assemblies” CIS Certification training class is designed for users to learn and to understand the basics of cable and wire harness fabrication and installation.  It is developed based on the approved comprehensive and technically accurate “IPC/WHMA-A-620A, Requirements and Acceptance for Cable and Wire Harness Assemblies” industry consensus standard.

 IPC/WHMA-A-620 describes acceptability criteria for crimped, mechanically secured and soldered interconnection and the corresponding lacing/restraining criteria associated with cable and harness assemblies.  Classes of products are defined and include criteria for Target, Acceptable, Process Indicator and Defect conditions to support the collection of visual quality acceptability requirements for each class.

Certification demonstrates commitment to customer requirements and greatly facilitates certification to ISO Certification or other quality assurance initiatives. By having earned this portable credential, you'll receive immediate recognition, legitimacy and value throughout the electronics industry.

Students who successfully complete this class will receive the IPC/WHMA-A-620 CIS (Certified IPC Application Specialist) certification, which is valid for two (2) years.  Our IPC/WHMA-A-620 CIS Re-Certification class is a 2-day extensive review of the “IPC/WHMA-A-620, Requirements and Acceptance for Cable and Wire Harness Assemblies” specifications and is designed for students who are required to renew their certification prior to expiration.  Students will participate in an overview and discussion of the “IPC/WHMA-A-620, Requirements and Acceptance for Cable and Wire Harness Assemblies” standard.  When there are revisions and/or amendments to this standard, students will discuss the applicable changes.

Our small, warm classroom size offers a nice, casual, relaxing and comfortable setting and is conducive to your learning.  Our goal is to make your learning experience a worthwhile, enlightening and enjoyable one!  All required training tools, equipment, accessories and materials will be provided to you, for your effective learning.   You simply show up and ready to learn & enjoy! 

Our normal class schedule is 8:00 am to 5:00 pm daily, although we’re flexible and will be happy to accommodate your special schedule circumstance as best as we possibly can, to ensure your timely training need & requirement.  Also, we offer both on-site and off-site classes to our students, including customized training.  You may participate in our standard classes, which are offered to the general public, that are held off-site at our facility.  And for group training, if you wish, for your convenience, we will be happy to conduct the class on-site at your facility.    

Although the IPC classes are industry-standard certification courses, our instructor understands that your work is important to you and that you want the right training which

meets your specific requirements; hence in addition to IPC’s standard class curriculum, we also offer the flexibility to include additional customized training to address your precise training needs, as necessary.  Simply advise us.  We want to provide you with the best, value-added training available, that is advantageous to you and to your business organization, and we're excitedly looking forward to being of service to you!

Should my organization consider IPC training & certification for our associates?

If your organization is involved in electronics manufacturing, you should definitely consider IPC training & certification for personnel who are involved in the production of circuit boards and assemblies. 

Electronics assembly normally involves a great amount of labor-intensive work, such as hand soldering and repair & rework techniques.  Even today, much of an assembly’s quality & reliability depends on the ability and consistency of the skilled operators.  

In 1995, IPC responded to requests for an official industry-standard training & certification program for electronic assembly acceptance, while the U.S. Department of Defense (DoD) certification programs were being cancelled.  With so many operators and technicians in facilities around the world, skills, knowledge, as well as experiences, vary vastly, IPC realized that a healthy electronics manufacturing industry was reliant upon standardized training, uniform procedures, and guidelines for everyone involved in lieu of unique, different ways of doing things. 

The IPC programs also greatly facilitate ISO certification, which has become important in international trading.   ISO quality programs require documented training programs, which are successfully fulfilled by the IPC industry-developed training classes.  Today, the IPC training and certification program contributes to the high quality and reliability of electronics assemblies everywhere, including the avionics & aerospace, automotive, and medical electronics industries. 

Many companies have implemented the IPC training and certification program with excellent results, and share the following common beliefs, values, and appreciations for its impressive impact (ref. IPC Review, Oct/Nov 2007 Issue).

“Education and training are critical elements for the success of any organization, particularly in fundamental skills such as hand soldering, electronics assembly, and inspection.   Participation in IPC programs has been crucial for providing standardized, industry-accepted skills as efficiently & effectively as possible.  Our customers expect our operators to be certified to IPC standards and that our product is assembled to the quality levels defined by IPC standards.  Our success with defect prevention and elimination, process control, methodology, and technology leadership is closely aligned with the success of our IPC training & certification implementation.”         

“Participation in the IPC training & certification program allows our company to ensure that practical, beneficial, and standardized training is included in industry-used programs.  Through the use of these programs, consistent training is established that allows employees the versatility to move from one product type to another.  Using industry-accepted programs also assures our customers of the skills and knowledge of our employees.  Quality-build product is accomplished when you empower employees with the knowledge and verification of your customers’ specified requirements.”

“IPC training & certification is vital to our business.  When we approach a new customer, the fact that our people have been trained to IPC-A-610 is a big selling point.  It gives the customer confidence in our ability to provide quality product to the industry’s highest standards.  A key advantage to IPC training is that it involves all of the technicians at once; they all learn together at the same time.  This enhances their ability to work together, collaborate, and support one another’s skills levels.”
