The definition of multilayer PCB is a PCB that is made with three or more conductive copper foil layers. These appear as several layers of double-sided circuit boards, laminated and glued together with layers of heat-protective insulation between them. The entire construction is arranged so that two layers are placed on the surface sides of the PCB to connect to the environment. All electrical connections between the layers are achieved with vias such as plating through holes, blind and buried vias. Application of this method then leads to the generation of highly complex PCBs of varying sizes.

What Is a PCB Prototype?
A PCB prototype is essentially an early sample of a product, built with the purpose of testing the design idea to see if it works. While most prototypes are made simply to test basic user functionality, PCB prototypes have the added need to be somewhat, if not entirely, functional. This is because PCB prototypes are made to test the total functionality of the design.
What is functional testing?
Functional testing: What works in theory doesn’t always work in practice. Accurate PCB boards will help assess the theoretical values of the board to see if they show up in the practical values. This allows any differences in value to be checked, updated and potentially reevaluated.
What is a DRC tool?
Design-rule-check (DRC): While DRC tools are extremely helpful to catch glaring problems in a design , they have limitations. As an example, DRCs can verify that a return path to ground exists, but may not determine the best trace geometry, size and length to get the best results from that path.
