What is a Build-up board?

A build-up board is a printed circuit board that has many layers laminated. By using a build-up board, it is possible to use a high-density board with a small area, so you can create multi-functional products even with small devices. A build-up board is made up of multiple layers of conductors and insulators, and laser drilling and wiring are performed to penetrate the layers, making it possible to obtain a complex board with a small area.
