1) Thickness: 0.1mm-5mm

2) Minimum linewidth：0.075mm/3mil

3) Minimum gap：0.065/2.8mil

4) Minimum aperture inradium：0.15mm

5) Minimum aperture external diameter：0.45mm

6) Minimum BGA: 0.2mm

7) Layer：4 layers through hole non-impedance 

All multilayer boards are printed with 36t screen, the resistance welding oil is 50 tons thicker than the traditional 43t, which provides reliability guarantee for the bga and more precise fine lines.
