1-2 layers: 0.4-2.4mm 4 layers: 0.8-2.4mm 6 layers: 1.2-2.4mm |
Thickness Tolerance ( t≥1.0mm) |
± 10% |
Normally take positive tolerance due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface. |
Thickness Tolerance ( t<1.0mm) |
±0.1mm |
Normally take positive tolerance due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface. |
Min Trace |
4mil(0.1mm) |
Minimum trace width is 4mil, strongly suggest to design trace above 6mil (0.15mm) to save cost. |
Min Spacing |
4mil(0.1mm) |
Minimum trace spacing is 4mil, strongly suggest to design trace above 6mil (0.15mm) to save cost. |
Finished Outer Copper Thickness |
1 oz/ 2oz (35um/75um) |
Thickness of outer copper foil is 1oz or 2oz 1 oz=35um,2 oz=70um |
Finished Inner Copper Thickness |

Annular Ring |
≥0.153mm(6mil) |
It doesn’t limit the size of the single side of the annular ring if there is enough space. Or annular ring surrounded by traces should be equal to or larger than 6mil. |
Finished Hole Diameter (CNC) |
0.25--6.5mm |
Due to the copper attached to the inner wall of the hole, the diameter of the finished hole is generally smaller than designed. |
Hole Size Tolerance (CNC) |
±0.075mm |
e.g. For the 0.6mm hole, the finished hole size between 0.525mm to 0.675mm is acceptable. |
Solder Mask |
Photosensitive ink |
Photosensitive ink is mostly adopted. Plastisol is used in the inexpensive paper-based boards.
|
Min Character Width (Legend) |
≥0.15mm |
Characters width less than 0.15mm will be unidentifiable. |
Min Character Height (Legend) |
≥0.8mm |
Characters height less than 0.8mm will be unidentifiable. |
Character Width to Height Ratio (Legend) |
1:5 |
1:5 is the most suitable ratio for production. |
Distance between Trace and Outline |
≥0.3mm(12mil) |
Ship as individual boards: Distance between Trace and Outline ≥0.3mm
Ship as Panelized boards with V-cut: Distance between Trace and V-cut line ≥0.4mm |
Panelization without Spacing |
0mm |
Ship as Panelized boards and the spacing between boards is 0mm. |
Panelization with Spacing |
1.6mm |
Make sure the spacing between boards should be ≥1.6mm, otherwise it will be hard to process routing. |
Half Hole Diameter |
Minimum Half hole Diameter: 1mm, No more than 10 holes. |
Half hole is a special technology, so half hole diameter should be greater than 1mm. |
Solder Mask Bridge |
0.1mm |
Please make a note, if there is solder mask bridge requirement. The price may rise. |
