Minimum drill hole diameter 0.15mm Mechanical drilling: minimum drill hole diameter 0.15 mm,Laser drilling: minimum drill hole diameter 0.1MM,If conditions permit, it is recommended that the minimum hole be designed to 0.3mm or more.Drilling tolerance: +0.075 mm
Minimum Linewidth Line Spacing ≥3/3mil ≥3/3mil (0.076mm) 4/4mil(finished copper thickness 1oz), 5/5mil (finished copper thickness 2oz), 8/8mil (finished copper thickness 3oz). Conditions permit recommendation to increase wire width and wire spacing.
Minimum Network Width Line Spacing ≥6mil/8mil ≥6mil/8mil (0.15/0.20mm) 6/8mil(finished copper thickness 1oz), 8/10mil (finished copper thickness 2oz), 10/12mil (finished copper thickness 3oz)
Minimum etched font width ≥8mil (0.20mm) More than 8mil (0.20mm) 8mil (finished copper thickness 1oz), 10mil (finished copper thickness 2oz), 12mil (finished copper thickness 3oz)
Minimum BGA, Bonding Pad ≥6mil (0.15mm) For example, the thickness of board is 1.6 mm, and the thickness of physical plate is 1.44 mm (T-1.6*10%) to 1.76 mm (T+1.6*10%).
Complete outer copper thickness 35-140 μm 35-140 um refers to the thickness of copper foil in the outer layer of finished circuit board
Complete inner copper thickness 17-70um 17-70um refers to the widths of two copper sheets in a circuit.
Signal line to outline spacing ≥10mil (0.25mm) Way of delivery :CNC,The distance between signal line and PCB outline space should be more than 0.25 mm.Way of delivery :V-CUT,The distance between route and V-CUT center line space should be more than 0.35 mm.When special pad and outline touch, customers are required to accept copper exposure on the side of the pad.
