BANNOCKBURN, IL – The latest update to the industry standard for rigid base materials provides clarification into the use of earlier revisions as called out on master drawings or in contracts.

“The incorporation of Amendment 1 into IPC-4101D removes the concerns with using revision D of IPC-4101 for all laminates and related prepregs in the fabrication of bare printed boards,” said Tom Newton, director of materials at IPC. “This amendment also clarifies the use of earlier revisions when required by customer specification or contract.”

IPC-4101D-WAM1, an amendment to IPC-4101D, Specification for Base Materials for Rigid and Multilayer Printed Boards, provides updates for board designers, buyers of board materials, fabricators and OEMs who use and keep boards current with base materials used in PCBs.  The revision covers requirements for laminate or prepreg base materials primarily used for rigid and multilayer PCBs for electrical and electronic circuits.

IPC-4101D-WAM1 contains 64 individual, keyword searchable specification sheets, including a brand new sheet that expands offerings for commercially available laminates and prepregs.
