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. Web9 jul. 2024 · CTE – Z axis (Co-efficient of thermal expansion): This is a measure of how much the base material will expand when heated. Measured as PPM/degree C (both before and after Tg) and also in % over a temperature range. Typical Low CTE High Tg PCB Material EM-827 827B.
