Number of Layers1-40 layersNA
Maximum PCB Size(Dimension)500x1100 mmAny sizes beyond this dimension, please contact us.
Board Size Tolerance(Outline)±0.2mm/±0.5mm±0.2mm for CNC routing, and ±0.5mm for V-scoring.
Board Thickness0.4-2.4mm0.4, 0.6, 0.8, 1.0, 1.2, 1.6, 2.0, 2.4mm. Please 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 Trace0.1mm/4milMin manufacturable trace is 4mil(0.1mm), strongly suggest to design trace above 6mil(0.15mm) to save cost.
Min Spacing Min manufacturable spacing is 4mil(0.1mm), strongly suggest to design spacing above 6mil(0.15mm) to save cost.
Outer Layer Copper Thickness1oz/2oz/3oz/4OZ or heavierWe make heavy copper PCB, as heavy as 30oz!
Inner Layer Copper Thickness 1oz/1.5oz(35μm/50μm)Inner copper weight as per customer's request for 4 and 6 layers. Please contact us if you need copper weight greater than 1.5oz.
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 Ring0.15mm(6mil)For pads with vias in the middle, Min width for Annular Ring is 0.15mm(6mil).
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.
Minimum Character Width(Legend) 0.15mmCharacters 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 Finishing Lead free HAL,Gold/Silver Immersion,Hard Gold,OSPNA
Solder MaskGreen, Blue, Red, White, Black, Matt black, Yellow, Purple, PinkGreen, Blue, Red, White, Black is standard offer, and other color need extra charge
Silkscreen White, Black, NoneNo extra charge.
Panelization V-scoring,Tab-routing,Tab-routing with Perforation (Stamp Holes)Leave min clearance of 1.6mm between boards for break-routing. For V-score panelization, set the space between boards to be zero.
