Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This revision includes more definitive preconditioning tests for surface mount PCD modules used for category 2 devices dc to dc converters.
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. This nearly page document attempts to standardize the performance parameters for ilc conversion devices including but not limited to the computer and telecommunications industries. 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.
IPC-9592 Critics Challenged to Get Involved
Copies of IPC can be purchased through www. 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 ipd applicable ; change history; and mechanical dimension measurements.
The IPC standard creates a set of consistent specifications and methods for the electronics industry.
It has come about due to a collaborative effort between major OEMs and power supply vendors. 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.
To provide a reliable power conversion product, the standard document sets forth a method of component derating to use in all electrical designs. Dc output power supplies to be embedded in equipment, whether the input power is ac or dc. Design and qualification testing is a central and detailed focus of IPC 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.
You may delete a document from your Alert Profile at any time. DFMEA activities are designed with three aims: This standard is also available to be included in Standards Subscriptions.
The intent of component derating is to improve reliability of electrical components in electronic products by compensating for many variables inherent in a design.

Derating ipd An important part of IPC involves derating documentation requirements and setting derating guidelines. 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. Proper component derating will lower failure rates through reduced stresses; reduce the 95992 of material, manufacturing, and operational variability; and enable continued circuit operation with long term part parameter shifts.
This has not existed prior to now and will prevent suppliers from having to perform unique sets of tests for each customer.
There should be a documented process in place to select all components for kpc designs including information on all components and all component suppliers. Expected reliability of a PCD and the conditions under which the reliability is specified should be defined by the supplier.

Add Comment Text Only character limit. Power conversion devices PCDs are used throughout the computer and telecommunications industries, but until now there was no defined standard for these devices. Already Subscribed to this document.
It will begin with a description of the standards development process and an outline of the subjects covered by the document. Your Alert Profile lists the documents that will be monitored.
Testing Standard – IPC-9592A
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. DFMEA is to be performed early in the power supply development cycle. When there is a custom PCD design 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 standard is not included in any packages.
We have no amendments or corrections for this standard. An important part of IPC involves derating documentation requirements and setting derating guidelines. The date and revision level should be marked at the bottom of the sheets. The testing described has two main purposes.
There was such urgency for the 9952 that it was released as iipc as the core features of it were in place, with work on a revision in progress even before the original standard was in print. Communications Power Published June 15, It sets the requirements for design, qualification testing, conformance testing, and manufacturing quality and reliability processes.
