Sequential Lamination

Many designs require more than a single lamination cycle. Some are two boards made separately and then bonded together to form the final board. Another is a board with all but one layer, with the final layer bonded after filling the vias of the first. Many newer designs need sequential layers bonded one by one to provide for stacked or staggered microvias.

For many materials, this causes over cure and degradation of the laminate material. This is not a problem with the 85N or 85HP products. These products have been used with six laminations and more without any sacrifice to the material performance.
