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. This document standardizes the requirements for power conversion devices PCDs for the computer and telecommunications industries.
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.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
New power conversion standard provides direction – Electronic Products
Subscription pricing is determined by: The date and revision level should be marked at the bottom of the sheets. Please first verify your email before subscribing to alerts. 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 power conversion devices including but not limited to the computer and telecommunications industries. Add Comment Text Only character limit. 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.
Design for reliability means that industry best practices to specify, design, and document PCD performance and reliability are in place. You may delete a document from your Alert Profile at any time. Communications Power Published June 15, Derating is a technique used to ensure that component ratings are not exceeded, either under steady state or transient conditions.
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. It is intended to set the requirements for design, qualification testing, conformance testing, manufacturing quality processes and regulatory requirements for power conversion devices.
IPC-9592 Critics Challenged to Get Involved
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.
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 ipf for all components; PCB artwork; component drawings, including magnetic; manufacturing drawings; 9529 reports if 959 ; change history; and mechanical dimension measurements.
This standard is also available to be included in Standards Subscriptions. 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.
HALT / HASS Standard – IPC A | ARL
The intent of component derating is to improve reliability of i;c components in electronic products by compensating for many variables inherent in a design. The 99592 will begin at 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.
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.
Tom Newton, director of technical programs for IPC explained that he was not surprised by the number or extent of the comments. 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. You can download and open this file to ipf own computer but DRM prevents 9529 this file on another computer, including a networked server.
It sets the requirements for design, qualification testing, conformance testing, and manufacturing quality and reliability processes.
Design and qualification testing is a central and detailed focus of IPC As the voice of the U. It will begin with a description of the standards development process and an outline of the subjects covered by the document.
Dc output power supplies to be embedded in equipment, whether the input power is ac or dc. Already Subscribed to this document. 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.
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.
The balance of the two days will be devoted to resolution of comments to the Final Draft.
Testing Standard – IPC-9592A
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. It describes derating methods, conditions, and results. 95992 defines the factors that should be incorporated into the component selection process.
