WebIPC-4101B Reference Chart. The table below is taken from IPC-4101B Specification for Base Materials for Rigid and Multilayer Printed Boards. The U.S. Department of Defense has adopted this specification. upon cancellation of MIL-S-13949. Although the specification itself includes additional information, the table below will help identify ... WebDelamination has occurred primarily on boards made from phenolic laminates, which are used for lead-free and high temp PCBs. While these materials have great thermal properties (Tg > 170C° and Td > 340C°, and conforming to IPC 4101/126/129), they are extremely weak in the fundamental areas of moisture absorption and copper to laminate adhesion.
