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±0.1mmNormally take positive tolerance due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface.
(t<1.0mm)
Min Trace4mil(0.1mm)Minimum trace width is 4mil, strongly suggest to design trace above 6mil (0.15mm) to save cost.
Min Spacing4mil(0.1mm)Minimum trace spacing is 4mil, strongly suggest to design trace above 6mil (0.15mm) to save cost.
Copper Thickness(35um/75um)1 oz=35um,2 oz=70um
Finished Inner1 oz (35um)Thickness of inner copper foil is 1 oz.

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

Drilling & Hole

CategoryCapabilityDetails
Drilling Size0.25--6.5mmFor 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 Width0.6mmFor HASL, the min. finished slot width is 0.45mm,for other surface finish, it is 0.5mm.
Board Thickness/Via Diameter≤6:17:1≤value≤8:1, add one more day for fabrication
PTH Deviation (Width)±4mil
PTH Deviation (Length)±5mil
NPTH Deviation (Width)±3mil
NPTH Deviation (Length)±4mil
Hole Wall Copper Thickness (Thinnest)≥0.71mil
Hole Wall Copper Thickness (Average)≥0.8mil
Via Space (Same Net)≥8mil
Via Space (Different Net)≥17mil
Min Space for Component Vias in Different Net≥24mil
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--6.5mmDue 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)±0.075mmE.g. For the 0.6mm hole, the finished hole size between 0.525mm to 0.675mm is acceptable.

Solder Mask

CategoryCapabilityDetails
Solder Mask: (TAIYO)Green ,Red, Yellow, Blue, White ,BlackNo extra charge (Green, White)
Silkscreen Color: (TAIYO)Green ,Red, Yellow, Blue, White ,BlackNo extra charge (Green, Black, White)
Solder MaskPhotosensitive inkPhotosensitive ink is mostly adopted. Plastisol is used in the inexpensive paper-based boards.

Min Character Width (Legend)≥0.15mmCharacters width less than 0.15mm will be unidentifiable.
Min Character Height (Legend)≥0.8mmCharacters height less than 0.8mm will be unidentifiable.
Character Width to Height Ratio (Legend)01:05:001:5 is the most suitable ratio for production.

Surface Treatment

CategoryCapabilityDetails
Surface FinishHASL, immersion gold, OSPHASL is not acceptable for 0.4mm board.

Special Technique

CategoryCapabilityDetails
Half Hole DiameterMinimum 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 Bridge0.1mmPlease make a note, if there is solder mask bridge requirement. The price may rise.
Panelization without Spacing0mmShip as Panelized boards and the spacing between boards is 0mm.
Panelization with Spacing1.6mmMake sure the spacing between boards should be ≥1.6mm, otherwise it will be hard to process routing.
