| 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) |
pAny 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" ill 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 |
 |
oz/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) |
 |
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 |
Green, Red, Yellow, Blue, White, Black, Purple, Matte black, Matte green |
| Silkscreen |
 |
White, Black, None |
White, Black, Yellow, Blue, Grey |
| 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. |
