Approach To This Document IPC/WHMA-A can be used as a stand-alone document for purchasing products; however it does not specify frequency of. IPS/WHMA-A is an individual level certification based on a standard published by IPC titled “Requirements and Acceptance for Cable and Wire Harness. IPC/WHMA-A Requirements and Acceptance for Cable and Wire Harness Assemblies.

Class 2 – Dedicated Service Electronic Products Includes products where continued performance and extended life is required, and for which uninterrupted service is desired but not critical. They also increase the chance of an intermittent or latent defect in the form of a short. Edit your existing full ipc/hwma-a-620a course PowerPoint files to replace the existing training slides in each included module as appropriate. The A describes requirements for assemblies based on visual criteria.
Additional languages are continuously being added. Am I caught in a double bind where these required test voltages are considered destructive and render the assembly unusable for service? Updates to Training Materials for Amendments These files are being made available to update existing training PowerPoints in each of the ipc/whms-a-620a courses with the changes in the Amendments for each course.
The costs of the testing should not increase when the voltage needs to be reduced. None of the information on this page is a substitute for having a copy of the A Rev B standard.
If you have a reason to believe that testing will degrade your pic/whma-a-620a, then you may want to perform some confirming tests and make use of a provision of the test section that requires ipc/whmx-a-620a tests on good assemblies to not degrade reliability.
Includes products where continued performance or performance-on-demand is critical, equipment downtime cannot be tolerated, end-use environment may be uncommonly harsh, and the equipment must function when required, such as life support systems and other critical systems.
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.
You may specify how cookies are being stored in your browser settings, but doing so may hinder site functionality. It also sets expectations between customers and suppliers for the level of quality expected.
The following words were added, Rev A: Instructor certification and re-certification training is conducted primarily at IPC Authorized Training Centers but may be conducted by the training center at company facilities. Even ipc/wgma-a-620a for industrial and commercial applications is usually tested in the manufacturing process. Certified Ipc/whma-a-6620a Trainers will participate in a week-long program that ipc/wham-a-620a 29 instructional hours.
By having earned this portable credential, you’ll receive immediate recognition, legitimacy and value throughout the electronics industry.
They are patterned after tests such as MIL-STD and other requirements that have existed for over 50 years and used on assemblies with much lower working voltages.
Class 3 – High Performance Electronic Products Includes products where continued performance or performance-on-demand is critical, equipment downtime cannot be tolerated, end-use environment may be uncommonly harsh, and the equipment must function when required, such as life support systems and other critical systems.
The following paragraph was ipc/wham-a-620a. To use the files:. Program Benefits Certification demonstrates commitment to customer requirements and greatly facilitates certification to ISO Certification or other quality assurance initiatives. When tested, the voltage used is in the thousands of volts.
Ipcwhma-a-620a are some sound reasons why this is not considered a risk: Certification is not revision specific. An optional eight-hour hands-on course is available.

These files are being made available to update existing training PowerPoints in each of the indicated courses with the changes in the Amendments for each course. Use of this standard requires agreement on the classes to which the product belongs. To shorten production test time without degrading the test, the IR test time ends as soon as the minimum resistance value is reached.

If you become aware of research that supports the fear of degrading insulation in wiring or connectors with the short-term application of high-voltage, we would deeply appreciate knowing of it. Username Password Remember Me Forgot your password? Verify the correct alignment on another blank sheet Print the verified version on the certificate. The following downloads apply to revision B of the Space addendum. Revision C materials are not yet available. Because of multiple parameters outside of IPC’s control: Ipcw/hma-a-620a have insulated wires or connectors with a specified maximum working voltage that is lower than those required in the A test specification.
Translated training materials for this program are available.
Detailed pictures communicate acceptable and unacceptable features of an assembly. Conductive connector shells and unused contact positions shall be included where a risk of a short exists. The A requirements specify that electrical tests should operate at such levels as not to degrade the electrical properties.
This seems backwards since the closer the spacing, the lower the voltage a connector is likely to be able to withstand.
IPC/WHMA A WITH HANDS-ON CIT –
In addition, the energy levels are very low test current is measured in mA and performed under room temperature conditions. Test time is very short and does not relate to the “working voltage” specifications. Shouldn’t they both be minimum times? Includes products suitable for applications where the major requirement is the function of the completed assembly. Class 1 – General Electronic Products Includes products suitable for applications where the major requirement is the function of the completed assembly.
Will these test voltages damage them? Click on the link for the desired course. This question most often arises from those doing work under military contracts where interpretations for different requirements may conflict. Printing a test copy on a blank piece of paper first.
Conductive connector shells and unused contact positions shall [N1D2D3] be included iipc/whma-a-620a a risk of a short exists. Edit your existing full training course PowerPoint files to ipc/dhma-a-620a or replace the existing training slides as appropriate. The Ipc/hwma-a-620a Section uses three product classes, as defined in section 1.
