Testing Standard – IPC-9592A

It will begin with a description of the standards development process and an outline of the subjects covered by the document. There was such urgency for the document that it was released as soon as the core features of it were in place, with work on a revision in progress even before the original standard was in print. There is a need for clearer requirements with respect to moisture sensitivity and corrosion and the higher temperatures associated with lead-free manufacturing need to be addressed.

Such documentation may include the theory of operation; applicable schematics; qualification test plan; reports for electromagnetic compatibility EMCsample qualification tests, design verification testing DVThighly accelerated life testing HALTSMT power module solder attachment reliability, and derating; reliability data and calculation; design checklist; failure mode and effect analysis FMEA for custom products; bill of materials BOM ; approved supplier list for all components; PCB artwork; component drawings, including magnetic; manufacturing drawings; regulatory reports if applicable ; change history; and mechanical dimension measurements.

Derating is a technique used to ensure that component ratings are not exceeded, either under steady state or transient conditions. Design and qualification testing is a central and detailed focus of IPC Second, environmental stress testing, including HALT, is intended to provide a measure of assurance not proof that the device is robust enough to operate in its intended environment without damage or degradation that would affect its operation.

Product specifications and documentation requirements should follow specific guidelines and appear in a delineated format. Tom Newton, director of technical programs for IPC explained that he was not surprised by the number or extent of the comments. Companies interested in reviewing the draft document and participating in the meeting can access the document and meeting registration form by visiting http: Communications Power Published June 15, This nearly page document attempts to standardize the performance parameters for power conversion devices including but not limited to the computer and telecommunications industries.

We have no amendments or corrections for this standard. The resulting document provides a cohesive direction for best practices in design and test of power products and clearly establishes a uniform set of qualification and manufacturing test requirements.

These specifications apply to suppliers of PCDs and provide guidelines for the end user to ensure adequate specs for use of these PCDs in their products.

In addition, the PCD supplier needs to implement a documented, capable material control system for all incoming, in-process, and outgoing materials and make available documentation of a material control plan.

The IPC standard creates a set of consistent specifications and methods for the electronics industry. The specification sets the requirements for design, qualification testing, conformance testing, manufacturing quality processes, and regulatory requirements, but does not include the functional requirements of the specific equipment.

Please first verify your email before subscribing to alerts. The testing described has two main purposes. Expected reliability of a PCD and the conditions under which the reliability is specified should be defined by the supplier. This standard is also available to be included in Standards Subscriptions.

It has come about due to a collaborative effort between major OEMs and power supply vendors. Design for reliability means that industry best practices to specify, design, and document PCD performance and reliability are in place. Revision A also expands the coverage of moisture sensitivity levels MSLs for PCDs and addresses corrosion of PCDs in various commercial, manufacturing and uncontrolled external environments.

This document standardizes the requirements for power conversion devices PCDs for the computer and telecommunications industries. Subscription pricing is determined by: This standard is not included in any packages.

Power Supply ESS: A case study evaluating IPC A recommendations – Electronic Products

The supplier must provide the user with pertinent documentation in a reasonable time frame, before the evaluation of engineering first article samples, and with appropriate nondisclosure agreement protection executed. An important part of IPC involves derating documentation requirements and setting derating guidelines. The datasheet should provide complete specifications of form, fit, and function, including electrical specifications and whether it is a Class 1, general or standard PCD, or Class 2, enhanced or dedicated service PCD.

The intent of component derating is to improve reliability of electrical components in electronic products by compensating for many variables inherent in a design. Already Subscribed to this document.

IPC-9592 Critics Challenged to Get Involved

Add Comment Text Only character limit. The current language on HALT is not enough to give suppliers clear guidance that would ensure meeting customer requirements, so more guidance and examples will be included with respect to HALT testing.

The purpose of IPC is to create a set of consistent specifications and methods to assure suitability, quality, safety and reliability of PCDs for the electronics industry.

Proper component derating will lower failure rates through reduced stresses; reduce the impact of material, manufacturing, and operational variability; and enable continued circuit operation with long term part parameter shifts. Please login to comment on the article.

We can only hope that if a technologist or company has an issue with how the document is written, they will engage in the process and make a contribution by carefully reviewing the document and participating in the June meeting.

It describes derating methods, conditions, and results. The PCD purpose The purpose of IPC is to create a set of consistent specifications and methods to assure suitability, quality, safety and reliability of PCDs for the electronics industry.
