|1-24 copper layers PCB prototypes
|Controlled Impedance PCB
|No extra charge and only accept our default layer stack-up
|FR-4 board material
|For Single & Double Layer, the maximum dimension is 400x500mm; For Multi Layer PCB, the maximum dimension is 300x300mm.
|Dimension Tolerance (Outline)
|±0.2mm for CNC routing, and ±0.2mm for V-scoring
|Liquid Photo-Imageable Solder Mask is the most common mask type. No extra fee for different color of solder mask.
| Thickness Tolerance
|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 (Thickness<1.0m m)
|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).
|Finished Outer Layer Copper
|Finished outer layer copper weight is 1oz or 2oz
|Finished Inner Layer Copper
|Finished inner layer copper weight is 0.5 oz only
|For Single & Double Layer PCB, the minimum trace width is 5 mil; For Multi Layer PCB, the minimum trace width is 3.5mil.
|For Single & Double Layer PCB, the minimum spacing is 5 mil; For Multi Layer PCB, the minimum spacing is 3.5mil.
|Min. Via hole size
|For Single & Double Layer PCB, the minimum via hole size is 0.3mm; For Multi Layer PCB, the minimum via hole size is 0.2mm.
|Min. Via diameter
|For Single & Double Layer PCB, the minimum Via diameter is 0.6mm; For Multi Layer PCB, the minimum via diameter is 0.45mm.
|Via To Trace
|Minimum distance between via(plated holes) and trace is 5mil.
|Drill Hole Size
|Min. drill size is 0.2mm, Max. drill size is 6.3mm.
|Hole Size Tolerance
|E.g. For the 0.6mm hole, the finished hole size between 0.52mm to 0.68mm is acceptable.
|Annular ring surrounded by traces should be equal to or larger than 3mil
|Min. Character Width
|Characters width less than 6mil(0.153mm) will be unidentifiable.
|Min. Character Height
|Characters height less than 32mil will be unidentifiable.
|Trace to Outline
| Ship as individual board(Routing): Trace to Outline ≥0.2mm;
Ship as panel with V- scoring: Trace to V-cut line ≥0.4mm
|Penalization without space
|Penalization with space
|Make sure the space between boards should be ≥2mm, otherwise it will be hard to process for routing.
|Min. Edge Rails
|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
|Keep out Layer/Mechanical Layer
|Only choose one from Keep out 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.
