Dear JLCPCB customers,
JLCPCB will be closed from Jan 30th to Feb 11th(GMT+8) to celebrate the Chinese New Year. To avoid unnecessary delays to your project, please kindly schedule your orders ahead of time.
Here's the detail of our holiday schedule>>.
Please select your shipping destination & currency & Price may differ based on your Shipping destination.
1-6 copper layers PCB prototypes
FR-4 board material
Maximum dimension is 400x500mm
±0.2mm for CNC routing, and ±0.2mm for V-scoring
Liquid Photo-Imageable Solder Mask is the most common mask type.
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%)
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
1 oz/2 oz (35um/75um)
Finished outer layer copper weight is 1oz or 2oz
Finished Inner Layer Copper
0.5 oz (17um)
Finished inner layer copper weight is 0.5 oz only
For Single&Double Layer PCB, the minimum trace width is 5 mil;
For Single&Double Layer PCB, the minimum spacing is 5 mil;
Min. Via hole size
For Single&Double Layer PCB, the minimum via hole size is 0.3mm;
Min. Via diameter
For Single&Double Layer PCB, the minimum Via diameter is 0.6mm;
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. Any holes greater than 6.3mm will charge extra fee
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(Rounting):
Ship as panel with V-scoring:
Panelization without space
Panelization with space
Make sure the space between boards should be ≥2mm, otherwise it will be hard to process for rounting.
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
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.
Soldermask Bridge/Blind and buried vias are not available now
