Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially

X7R >Z5U,Y5V Greater means less likely to crack or in other words NP0 is better than X7R for crack resistance. Don't think that there is a set formula. There isn't! I cracked ceramic resonators at 0.050" from the board edge with CAB M2 and M3 dep

Background on the PCB: Thickness: .032" Material: Standard Fr4 V-score: Leaves .016" (approx .008" cuts on either side) We are having some issues on these boards where the edges are delaminating all the way to the copper during de-panel. Now, we are
