From a technical point of view, multi circuit boards have several
advantages in design, such as small size, lightweight construction, high
quality, high durability, high flexibility, etc.
FR-4 is a common material for printed circuit boards (PCBs). A thin
layer of copper foil is usually laminated to one or both sides of the
FR-4 glass epoxy panel. FR-4 PCB Board is both a name and a standard
grade.
