| 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. |
| Copper Thickness (Inner Copper) | 18~70um(i.e.0.5Oz~2Oz) | 1 oz＝35um |

Drilling & Hole
| Category | Capability | Details |
| Drilling Size | 0.2--6.5mm | For vias larger than 6.5mm, multiple drilling or milling is recommended |
| PTH Deviation | ±3mil | |
| NPTH Deviation | ±2mil | |
| Hole Position Deviation | ±3mil | |
| Hole Wall Roughness（Max） | 1.5mil | |
| Min Slot Width | 0.6mm | For HASL, the min. finished slot width is 0.45mm，for other surface finish, it is 0.5mm. |
| Board Thickness/Via Diameter | ≤6：1 | 7:1≤value≤8:1, add one more day for fabrication |
| PTH Deviation (Width) | ±4mil | |
| PTH Deviation (Length) | ±5mil | |
| NPTH Deviation (Width) | ±3mil | |

| 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) | 0.2--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

| Silkscreen Color: (TAIYO) | Green ,Red, Blue, White ,Black | No extra charge (Green, Black, White) |
| Solder Mask | Photosensitive ink | Photosensitive ink is mostly adopted. Plastisol is used in the inexpensive paper-based boards. |
| 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

| Surface Finish | HASL, Immersion gold / sliver / tin, OSP, Hard Gold plating, Soft gold plating, NiPdAu | HASL is not acceptable for 0.4mm board. |
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. |
| Other | V cut, Metal edging, Resin plug hole, Gold finger bevel | |
| Certificate | ISO9001、ISO14001、UL、QC080000、IATF16949 CQC、ISO 13485(As Required) |
