Cap layers (metal layers 2 & 5) can then be laminated, drilled, plated, and circuitized, followed by an oven exposure to advance the cap layers’ nematic melt points. WebbIt's quite important to control components and amount of additives and the failure of component control leads to bad copper filling of blind vias or empty cave, as is shown in Figure 3. The resolution to the failure of empty cave caused by this reason lies in the control in terms of additive components and additive amount, including: a. std testing freedom
