Advanced sequential lamination technology allows printed circuit board (PCB) manufacturing to be made up of different subsets of boards and layers

 A subset of PCB is a multi-layered printed circuit board that is presented in an almost complete PCB process. Sequential lamination is a multi-layer PCB technology. Sub-parts (or sub-composites) that have been laminated to additional copper or other sub-parts. Sequential laminated printed circuit boards (PCBs) go through at least two laminate cycles and can go through more, The resulting structure is then submitted to the required additional PCB treatment steps, such as drilling, plating, etching and surface treatment.

If an application requires multiple press-fit and laminate cycles, it is called sequential build-up or SBU technology.

This construction method is the pillar of high density interconnection (HDI) products and has been used in many forms. This technology as a whole has been very successful, and today it is essential for mobile communications and computer chip packaging, as well as many other uses. Many of these products are small, light and thin.
