Board Thicknessboard thickness0.2-2.4mm0.2,0.4, 0.6, 0.8, 1.0, 1.2, 1.6, 2.0, 2.4mm. Please view the below "Standard PCB" or contact us if your board exceeds these.
Board Thickness Tolerance(t≥1.0mm) -±10%Normally “+ Tolerance” will occur due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface.
Board Thickness Tolerance(t<1.0mm) -±0.1mm
Min TraceMin Trace Min Spacing0.1mm/4milMin manufacturable trace is 4mil(0.1mm), strongly suggest to design trace above 6mil(0.15mm) to save cost.
Min SpacingMin manufacturable spacing is 4mil(0.1mm), strongly suggest to design spacing above 6mil(0.15mm) to save cost.
Outer Layer Copper ThicknessOuter Layer Copper Thickness1oz/2oz/3oz(35μm/70μm/105μm)Also known as copper weight. 35μm=1oz, 70μm=2oz, 105μm=3oz. Please view the below "Standard PCB" or contact us if you need copper weight greater than 3oz.
Inner Layer Copper ThicknessInner Layer Copper Thickness1oz/1.5oz(35μm/50μm)Inner copper weight as per customer’s request for 4 and 6 layers (Multi-layer laminated structure). Please contact us if you need copper weight greater than 1.5oz.
Drill Sizes (CNC)drill Sizes (CNC)0.2-6.3mmMin drill size is 0.2mm, max drill is 6.3mm. Any holes greater than 6.3mm or smaller than 0.3mm will be subject to extra charges.
Min Width of Annular RingMin Width of Annular Ring0.15mm(6mil)For pads with vias in the middle, Min width for Annular Ring is 0.15mm(6mil).
Finished Hole Diameter (CNC)Finished Hole Diameter (CNC)0.2mm-6.2mmThe finished hole diameter will be smaller than size of drill bits because of copper plating in the hole barrels
Finished Hole Size Tolerance(CNC)-±0.08mmFor example, if the drill size is 0.6mm, the finished hole diameter ranges from 0.52mm to 0.68mm will be considered acceptable.
Solder Mask PCB Solder MaskLPILiquid Photo-Imageable is the mostly adopted. Thermosetting Ink is used in the inexpensive paper-based boards.
Minimum Character Width(Legend)PCB Silkscreen0.15mmCharacters of less than 0.15mm wide will be too narrow to be identifiable.
Minimum Character Height (Legend)-0.8mmCharacters of less than 0.8mm high will be too small to be recognizable.
Character Width to Height Ratio (Legend)-1:5In PCB silkscreen legends processing, 1:5 is the most suitable ratio
Minimum Diameter of Plated Half Holes-0.6mmDesign Half-Holes greater than 0.6mm to ensure better connection between boards.
Surface FinishingSurface FinishingHASL with lead
HASL lead free
Immersion gold,OSP
The most popular three types of PCB surface finish. Please view the below "Standard PCB" or contact us for other finishes.
Solder MaskSolder MaskGreen ,Red, Yellow, Blue, White ,Black
