IPC Standards Committee Reports: Supplier Declaration, Electronic Documentation, Flex Circuits, Conflict Minerals

These standards committee reports from IPC’s Fall Standards Development  Committee Meetings have been compiled to help keep you up to date on IPC  standards committee activities. This is the third and final report in the series.

Supplier Declaration

The 2-18 Supplier Declaration Subcommittee discussed the need to revise IPC-1751A, General Requirements for Declaration Process Management. The revision will facilitate the harmonization of the IPC-175x family of standards with the IEC 62474 materials declaration standard. The subcommittee will restructure the 175x family of standards to allow the laboratory declaration standard (IPC-1753) and conflict minerals standard (IPC-1755) to be part of the IPC-175x family of standards.

The second amendment to IPC-1752A, Materials Declaration Management passed unanimously. The amendment helps to ensure a seamless transition toward harmonization with the IEC 62474 materials declaration standard. The 2-18b Materials Declaration Task Group, responsible for IPC-1752A, also discussed implementing a requirement for solution providers to undergo a yearly review to ensure the latest released standards, schemas and IPC lists of substance categories and exemptions are followed.

The 2-18f Declaration of Shipping, Pack and Packing Materials Task Group discussed amending IPC-1758, Declaration Requirements for Shipping, Pack and Packing Materials, to include a field for declaring recycled content of packaging material. The task group will propose an amendment after IPC-1751A, General Requirements for Declaration Process Management, is revised.

The 2-18h Conflict Minerals Data Exchange Task Group responded to comments received on the Proposed Standard for Ballot on IPC-1755, Conflict Minerals Data Exchange, which did not pass the first round of balloting. The committee agreed on important changes, as suggested by committee members, to help ensure the standard passes the next circulation. Publication of a final standard is expected by January 2014.

The 2-18j Lab Report Declaration Task Group celebrated the approval of IPC-1753, Laboratory Report Declaration. The standard allows laboratory data to be seamlessly exchanged between supply chain partners.

Electronic Documentation Technology

The 2-40 Electronic Documentation Technology Committee has turned its attention to providing electronic formats for both printed board and assembly standards using IPC-2581B schema concepts. The committee has started work on Revision A of IPC-2614, Sectional Requirements for Board Fabrication Documentation. During the meeting, the committee proposed amendments to the standard as well as incorporating suggested modifications to the image standards for schematics and logic diagrams (IPC-2612 and IPC-2612-1).

The 2-41 Product Data Description Subcommittee reviewed the data model for laminate construction and converted a portion of it into the XML schema identified in IPC-2581. The group determined the requirements for laminate description and the details needed to define specific laminate properties, such as dielectric constant, glass transition temperature, glass weave, and thermal processing properties. These will be documented in a new standard, IPC-2614-1.

Flexible Circuits

The D-12a UL 746F and UL 796F Task Group was re-activated in August 2013 at the request of UL. The organization is revising the UL 796F flexible printed wiring standard. The group commented upon the prioritized listing of topics proposed for change.

The D-13 Flexible Circuits Base Materials Subcommittee addressed the latest resolved comments on Amendment 1 to IPC-4202A, Flexible Base Dielectrics for Use in Flexible Printed Circuitry. The final draft of this amendment will be sent out for comments for resolution prior to ballot. The subcommittee is also revising IPC-FC-234, PSA Assembly Guidelines for Single- & Double-Sided Flexible Printed Circuits. This document covers the use of pressure sensitive adhesives (PSA) in assembly.

Conflict Minerals

The E-30 Conflict Minerals Due Diligence Committee reviewed sample draft text that was prepared in response to comments agreed upon during the February 2013 meeting at IPC APEX EXPO. Committee members will complete a re-draft this fall and circulate it for comments in early 2014 with the intention of reviewing comments during the committee’s next meeting in March 2014.
