What is a Multilayer PCB?
A multilayer PCB consists of four or more conductive copper layers stacked and bonded together with insulating material. These layers are interconnected using plated vias, enabling highly complex circuit routing within a compact footprint. Multilayer PCBs are essential for modern electronics requiring high speed, signal integrity, and space optimization.
