| Number of Layers |
|
1-10 layers |
For orders above 10 layers,please view the below "Standard PCB" or contact our sales rep. |
| Material |
|
FR-4,Aluminum |
For Flex, Rigid-flex, Metal-based (Aluminum etc.,), HDI, Halogen-free, High Tg, etc.,please view the below "Standard PCB" or contact sales rep. |
| Maximum PCB Size(Dimension) |
|
500*1100mm (min 5*6mm) |
Any sizes beyond this dimension, please view the below "Standard PCB" or contact sales rep. |
| 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. 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 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 view the below "Standard PCB" or 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. |
| 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 Holes |
|
0.6mm |
Design Half-Holes greater than 0.6mm to ensure better connection between boards. |
| Surface Finishing |
|
HASL 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 Mask |
|
Green ,Red, Yellow, Blue, White ,Black |
No extra charge (Green, Red, Yellow, Blue)
|
| Silkscreen |
|
White, Black, None |
No 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. |
| Others |
|
Fly Probe Testing (Free) and A.O.I. testing(free), ISO 9001:2008 ,UL Certificate |
No extra charge. |
