Companies interested in reviewing the draft document and participating in the meeting can access the document and meeting registration form by visiting http: It has come about due to a collaborative effort between major OEMs and power supply vendors. First, design verification testing and electromagnetic susceptibility testing, including electromagnetic interference EMI and electrostatic discharge ESD testing, are intended to provide assurance that the device will function according to its specification.

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.
DFMEA is to be performed early in the power supply development cycle. Dc output power supplies to be embedded in equipment, whether the input power is ac or dc. The IPC standard creates a set of consistent specifications and methods for the electronics industry. It will begin with a description of the standards development process and an outline of the subjects covered by the document.
Power conversion devices PCDs are used throughout the computer and telecommunications industries, but until now there was no defined standard for these devices.
Communications Power Published June 15, Design for reliability means that industry kpc practices to specify, design, and document PCD performance and reliability are in place.
This has not existed prior to now and will prevent suppliers from having to perform unique pic of tests for each customer. Copies of IPC can be purchased through www. 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. Design and qualification testing is opc central and detailed focus of IPC Already Subscribed to this document.
The meeting will begin at Derating is a technique used to ensure that component ratings are not exceeded, either under steady state or transient conditions. Product 952 and documentation requirements should follow specific guidelines and appear in a delineated format. 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.

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 ipcc its operation.
Testing Standard – IPC-9592A
It is intended to set the requirements for design, qualification testing, conformance testing, manufacturing quality processes and regulatory requirements for power conversion devices. To provide a reliable power conversion product, the standard document sets forth a method of component derating to use in all electrical designs. As the voice of the U. IPC defines the factors that should be incorporated into the component selection process. opc
New power conversion standard provides direction – Electronic Products
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 95592 progress opc before the original standard was in print. Subscription pricing is determined by: If the document is revised or amended, you will be notified by email. 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.
This nearly page document attempts to standardize the performance parameters for power conversion devices including but not limited to the computer and telecommunications industries.
The balance of the two days will be devoted to resolution of comments to the Final Draft. 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.
IPC-9592 Critics Challenged to Get Involved
When there is a custom PCD pic on new topologies or architectures with no previous design failure modes and effects analysis DFMEAor in cases where there are new technology components, the supplier should provide a DFMEA to the customer with results of the analysis and of any corrective actions.
This document standardizes the requirements for power lpc devices PCDs for the computer and telecommunications industries. This standard is also available to be included in Standards Kpc. The intent of component derating is to improve reliability of electrical components in electronic products by compensating for many variables inherent in a design.
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. Please first verify your email before subscribing to alerts.
An important part of IPC involves derating documentation requirements and setting derating guidelines. It sets the requirements for design, qualification testing, conformance testing, and manufacturing quality and reliability processes. The level of documentation will differ between custom and standard PCDs, as agreed by the user and the supplier; with custom PCDs typically requiring significantly greater detail ex.
The datasheet should provide complete specifications of form, fit, and function, including electrical specifications lpc whether it is a Class 1, general or standard PCD, or Class 2, enhanced or dedicated service PCD. There should be a documented process in place to select all components for product designs including information on all components and all component suppliers.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The testing described has two main purposes. 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. Tom Newton, director of technical programs for IPC explained that he was not surprised by the number or extent of the comments. Ipf revision includes more definitive preconditioning tests for surface mount PCD modules used for category 2 devices dc to dc converters.

ipx We can only lpc 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. This standard is not included in any packages. The date and revision level should be marked at the bottom of the sheets. Expected reliability of a PCD and the conditions under which the reliability is specified should be defined by the supplier.
