| Max. PTH (Round Hole) | 8mm | |
| Max. PTH (Round Slot Holes) | 6*10mm | |
| 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

| 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) | 01:05:00 | 1:5 is the most suitable ratio for production. |
Surface Treatment

Special Technique
| Category | Capability | Details |
| 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. |
| 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. |
