Single or double layer PCB product introduce

Single sided and double sided boards, often called n-pth and pth boards, still represent a significant percentage of the printed circuit boards (also known with the acronym pcbs) produced every year worldwide.

Developing single or two layer PCB reason

Anyway more and more pcbs, independently of their sector of application, are nowadays manufactured using a technology known as multilayer technology.

Multi-layer PCB is develop from single PCB circuit board

The multilayer technology essentially introduces a vertical solution approach to the problem of the conflicting requests for extremely high number of interconnections and reduced sizes in a single printed circuit board.

You should know the theory of multi-layer PCB manufacturing

The interconnections among the active and passive components that are (typically) mounted on the top and bottom of the printed circuit board are realised in some internal layers that are pressed together and that can be then connected the one to the others (through blind and buried vias) and to the superficial (external) layers of the board (drilling through all vias).

The Common of multi-layer PCB and the double layer PCB

Basically, each internal layer of a multilayer printed circuit board is essentially a double sided pcb, but with no solder and finishes, and its manufacturing process requires the same steps of a standard double sided pcb, with the only exceptions mentioned above.
