14 Layer FR4 Rigid PCB

At Rigiflex, we take pride in designing and manufacturing specialized FR4 rigid PCBs. FR4 is a flame retardant, glass reinforced, epoxy laminate sheet. It is known to possess immense mechanical strength, and works extremely well as an electric insulator. FR4 laminates are often referred to as copper-clad laminates as thin layers of copper foils are laminated to the FR4 epoxy panel. At Rigiflex, we produce 14 layer rigid PCBs with copper thickness ranging between 1/H and H/1OZ. The board thickness of this kind of PCB is 2.0mm.The minimum hole size and the minimum line width spacing are both 3 mil. Besides FR4, we also use 14L and TG170 as base materials.
