In addition, there will be an increased focus on customers in countries such as China and India. Please first verify your email before subscribing to alerts. Product specifications and documentation requirements should follow specific guidelines and appear in a delineated format.
The testing described has two main purposes. 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 ilc technology components, the supplier should provide a DFMEA to the customer with results of the analysis and of any corrective actions.
It describes derating methods, conditions, and results.

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. We have no amendments or corrections for this standard. Derating is a technique used to ensure that component ratings are not exceeded, either under steady state or transient conditions.
Items to be addressed are input power logic, indicator, control, and output specifications; reliability, safety, and regulatory factors; physical dimensions and electrical specifications and requirements; and material control and labeling. The date and revision level should be marked at the bottom of the sheets. 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.
Communications Power Published June 15, 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 HALT99592 power module solder attachment reliability, 95992 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 ipx manufacturing drawings; regulatory reports if applicable ; change history; and mechanical dimension measurements.
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.
This standard is also available to be included in Standards Subscriptions. The IPC standard creates a set of consistent specifications and methods for the electronics industry. Power conversion devices PCDs are used throughout the computer and telecommunications industries, but until now there was no defined standard for these devices.

This ic is not included in any packages. The intent of component derating is to improve reliability of electrical components in electronic products by compensating for many variables inherent in a design.
Your Alert Profile lists the documents that will be monitored. The specification sets the requirements for design, qualification testing, conformance testing, manufacturing quality processes, and regulatory requirements, but does not include the ippc requirements of the specific equipment. Tom Newton, director of technical programs for IPC explained that he was not surprised by the number or extent of the comments.
Testing Standard – IPC-9592A
Please login to comment on the article. If the document is revised or amended, you will be notified by email. This has not existed prior to now and will prevent suppliers from having to perform unique sets of tests for each customer. It has 992 about due to a collaborative effort between major OEMs and power supply vendors.
Derating guidelines An important part of IPC involves derating documentation requirements and setting derating guidelines. Subscription pricing is determined by: Once a consensus has been achieved, the proposed standard will be sent to all IPC members for i;c vote.

Design and qualification testing is a central and detailed focus of IPC You may delete a document from your Alert Profile at any time.
This revision includes more definitive preconditioning tests for surface mount PCD modules used for category 2 devices dc to dc converters. Add Comment Text Only character limit. 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. As the voice of the U. It sets the requirements for design, qualification testing, conformance testing, and manufacturing quality and reliability processes.
The balance of the two days will be devoted to resolution of comments to the Final Draft. Design for reliability means that industry best practices to specify, design, and document PCD performance and reliability are in place.
DFMEA is to be performed early in the power supply development cycle. There should be a documented process in place to select all components for product designs including information on all components and all component suppliers.
It will begin with a description of the standards development process and an outline of the subjects covered by the document. 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. Expected reliability of a PCD and the conditions under which the reliability is specified should be defined by the supplier.
