1-6 copper layers PCB prototypes
FR-4 board material
Maximum dimension is 400x500mm
Dimension Tolerance (Outline)
±0.2mm for CNC routing, and ±0.2mm for V-scoring
Thickness Tolerance ( T≥1.0mm)
e.g. For the 1.6mm board thickness, the finished board thickness ranges from 1.44mm（T－1.6×10%）to 1.76mm（T＋1.6×10%)
Thickness Tolerance ( T<1.0mm)
e.g. For the 0.8mm board thickness, the finished board thickness ranges from 0.7mm（T-0.1）to 0.9mm（T+0.1).
Minimum trace width is 6 mil. More than 6mil is recommended to save cost
Minimum spacing is 6 mil. More than 6mil is recommended to save cost
Finished Outlayer Copper
1 oz/2 oz (35um/75um)
Finished outlayer copper weight is 1oz or 2oz
Finished Innerlayer Copper
0.5 oz (17um)
Finished innerlayer copper weight is 0.5 oz only
Drill Hole Size
Min. drill size is 0.3mm, Max. drill size is 6.3mm. Any holes greater than 6.3mm will charge extra fee
Annular ring surrounded by traces should be equal to or larger than 6mil(0.153mm)
Hole Size Tolerance
e.g. For the 0.6mm hole, the finished hole size between 0.52mm to 0.68mm is acceptable.
Liquid Photo-Imageable Solder Mask is the most common mask type.
Min. Character Width
Characters width less than 6mil(0.153mm) will be unidentifiable.
Min. Character Height
Characters height less than 1mm will be unidentifiable.
Trace to Outline
Rounting: Trace to Outline≥0.3mm; V-scoring: Trace to V-cut line≥0.4mm
Panelization without space
For V-scoring panelization, set the space between boards to be 0mm
Panelization with space
For Rounting panelization,set the space between boards to be ≥2mm.
Copper Hatching with Pads
We will apply Copper Hatching if your PCBs designed with Pads.
Slot Drawing with Pads
Please use Outline to design if there are many non-plated (NPTH) holes.
Protel/dxp Solder Layer
Do not mistake the Paste Layer as Solder Layer.
Protel/dxp Outline Layer
Keepout Layer/Mechanical Layer
Only choose one from Keepout Layer or Mechanical Layer as outline.
Min. Half Hole Diameter
Half hole is a special technology, so half hole diameter should be greater than 0.6mm.
