Dimensional Stability | 3 August, 2017

DCS testing has detected exotherming in samples of stock FR4 laminate material. The exotherming subsequently disappears from the heat flow plots when DSC testing is repeated a second time on the same samples. Can this non/ under-cured material cause localized warping or other dimensional instability issues in our finished PCBs?
