1-8 layer

1-8 copper layers PCB (Don't support Blind/Buried Vias)

Controlled Impedance PCB

4 and 6 layer

No extra charge and only accept our default layer stack-up

Material

FR-4

ALUMINIUM and FR-4

Max Size

60*50cm

Max size is 60*50cm

Solder Mask

LPI

green/blue/red/yellow/black, etc.

Finished Outer Layer Copper

1oz~2oz(35um~70um)

Finished outer layer copper is 1-2oz

Dimension Tolerance (Outline)

±0.15mm

Dimension tolerance(outline) is 0.15mm

Thickness

0.4~2.4mm

0.4/0.6/0.8/1.0/1.2/1.6/2.0/2.4mm

Thickness Tolerance (T≥1.0mm)

±10%

eg: For the 1.6mm board thickness, the finished board thickess ranges from 1.44mm(T-1.6*10%) to 1.76mm(T-1.6*10%)

Thickness Tolerance (T<1.0mm)

±0.1mm

0.7mm (T-0.1)~0.9mm (T+0.1)

Drill Holes Size

0.25~6.3mm

Min drill size is 0.2mm, Max drill size is 6.3mm

Hole Size Tolerance

±0.08mm

eg: For the 0.6mm hole, the finished hole size between 0.52mm to 0.68mm is acceptable

Min. Trace

3.5mil

For single&Double layer PCB,the minimum trace width is 5mil,For multi layer PCB, The minimum trace width is 3.5mil

Min. Spacing

4mil

For single&Double layer PCB,the minimum spacing is 5mil,For multi layer PCB, The minimum spacing is 4mil

Min. Via diameter

Min Inner Diameter(Hole):0.25mm,Min outer diameter:0.5mm

For multilayer pcb, min inner diameter(hole)0.25mm.min outer diameter:0.5mm For double layer PCB, min inner diameter :0.3mm, min
outer diameter :0.6mm

Pad to trace

6mil

Minimum distance betwen and trace is 6mil

MIn. Character Width and heigh

Min character width:4mil, Min character height:27.5mil

Character width less than 4mil(0.153mm)will be unidentifiable,Characters height less than 32mill be unidentiable

Trace to outline(Ship as individual board with Rounting)

≥0.2mm

Ship as individual board(Rounting):Trace to outline ≥0.2mm; Ship as panel with V-scoring: Trace to outline ≥0.4mm;

Trace to outline(Ship as panel with V-scoring)

≥0.4mm

Ship as panel with V-scoring: Trace to outline ≥0.4mm;

Min Strip

3mm

Panelization with space

1.6mm

Make sure the space between boards should be≥1.6mm,otherwise it will be hard to process for rounting

Min.Half Hole Diameter

0.8mm

Half hole is a special technology, so half hole diamter should be bigger than 0.6mm

Solder mask opening

0.05mm

If need solder mask bridge , it should be more than 4mil.

NOTE1:Copper hatching with software Pads

Hatching

We will supply Copper Hatching if your PCB designed with software Pads,Pls refer to the picture.

NOTE2:Slots designed with software Pads)

Outline

Please use outline to design if there are many non-plated(NPTH)holes
