|Number of Layers||1-10 layers||For orders above 10 layers, please contact our sales rep.|
|For Flex, Rigid-flex, Metal-based (Aluminum etc.,), HDI, Halogen-free, High Tg, etc., please contact sales rep.|
|Maximum PCB Size(Dimension)||500x1100 mm||Any 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 Thickness||0.4-2.4mm||0.4, 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 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/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)||0.2-6.3mm||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.|
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 Holes||0.6mm||Design Half-Holes greater than 0.6mm to ensure better connection between boards.|
|Surface Finishing||HASL with lead
HASL lead free
|The most popular three types of PCB surface finish. Please contact us for other finishes.|
|Solder Mask||Green ,Red, Yellow, Blue, White ,Black||
No extra charge (Green, Red, Yellow, Blue)
|Silkscreen||White, Black, None||
No extra charge.
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), ISO 9001:2008 ,UL Certificate||
No extra charge.
