Tolerances / Minimums Inner Layer Clearances - minimum of 0.010" Copper to Edge of Printed Circuit Board - minimum of 0.010" ( outer layers ) and 0.014" for inner layers. Add 5 mils if scoring is required. Pad Size / Annular Ring Pad size should be at least 0.010" greater than hole size / .005" added to radius of hole size. Hole Size +/- 0.005" standard +/- 0.002 available for press fit connector applications – must specify Board Thickness Minimum thickness 2 layer: 0.005" Minimum thickness for 4 layer: 0.020" Minimum thickness for 6 layer: 0.031" Minimum thickness for 8 layer: 0.047" Minimum thickness for 10 layer: 0.062" Tolerance on board thickness +/- 10% Inner layer ( core ) Thickness – same as single core laminates Board Outline ( Rout ) +/- 0.010 standard +/- 0.005 available upon request – must specify Slot Width – Applies to .062" thick boards Minimum 0.031" width standard Smaller widths available upon request with some restrictions – call Tab Rout Spacing Please allow .125" spacing between individuals boards if you provide the panelization. Silkscreen ( Legend ) Standard minimum line width – 0.005" Upon request - 0.003"
