Precise Muti-layered PCB Designation
l Six-layered BGA module PCB: Board thickness 1.0mm
Precise Six-layered PCB has a rigorous and compact layout, also it requires data differential circuits, equal sized signal circuits and impedance control. Hence, difficulty of circuit etching process is high.
Minimum Via diameter: 0.2mm
Minimum line width/space: 3.5mil.
