Our Capabilities

Items Manufacturing Capabilities Remarks
Number of Layers 1-40 layers Please contact us if you have a complex design and requirement.
Material FR-4 (TG135, TG150, TG170)
Maximum PCB Size (Dimension) 1000*1000mm Please contact us if your board is bigger than 600mm
Board Size Tolerance (Outline) ±0.2mm/±0.5mm ±0.2mm for CNC routing, and ±0.5mm for V-scoring.
Board Thickness 0.2-2.4mm 0.2,0.4, 0.6, 0.8, 1.0, 1.2, 1.6, 2.0, 2.4mm.
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 Trace 0.1mm/4mil Min 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 Thickness 1oz/2oz/3oz (35μm/70μm/105μm) Also known as copper weight. 35μm=1oz, 70μm=2oz, 105μm=3oz. Please contact us if you need copper weight greater than 3oz.
Inner Layer Copper Thickness 1oz/2oz/3oz (35μm/70μm/105μm) Inner copper weight as per customer’s request for 4 and 6 layers(Multi-layer laminated structure). Please contact us if you need inner copper weight greater than 2oz.
Drill Hole Diameter 0.2-6.3mm Min 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 Ring 0.15mm (6mil) For pads with vias in the middle, Min width for Annular Ring is 0.15mm (6mil).
Finished Hole Diameter (CNC) 0.2mm-6.2mm The finished hole diameter will be smaller than size of drill bits because of copper plating in the hole barrels
Finished Hole Size Tolerance (CNC) ±0.08mm For 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 LPI Liquid Photo-Imageable is the mostly adopted. Thermosetting Ink is used in the inexpensive paper-based boards.
Minimum Character Width (Legend) 0.15mm Characters of less than 0.15mm wide will be too narrow to be identifiable.
Minimum Character Height (Legend) 0.8mm Characters of less than 0.8mm high will be too small to be recognizable.
Character Width to Height Ratio (Legend) 1:5 In PCB silkscreen legends processing, 1:5 is the most suitable ratio
Minimum Diameter of Plated Half-cut Holes 0.6mm Design Half-cut Holes greater than 0.6mm to ensure better connection between boards.
Surface Finishing HASL with lead, HASL lead free, Immersion gold, OSP
Solder Mask Green, Red, Yellow, Blue, White, Black
Silkscreen White, Black
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.
Others Fly Probe Testing (Free) and A.O.I. testing(free),UL Certificate
