PCB Capabilities

ITEM Capability Details Notes
Layer count 1~10 layers The number of copper layers in the board. At present, ZXHPCB only accepts 1~10 layers of through-hole plates (buried blind-hole plates are not accepted)
Multilayer PCB Controlled Impedance 4 layer、6 layer、8 layer、10 layer Multilayer PCB support impedance design
Material FR-4 FR-4
The whole process Max. Dimension 122cm*55cm Both sides can't be >55cm at the same time (one side can be 122.9cm, the other side would have to be <55cm)
Soldermask Type Photosensitive ink(green,Blue,Red,Yellow,White,Black,Matte Black) Photopolymer inks are the most used type nowadays, and heat-set oils are generally used in low-grade single-sided cardboard.
Finished Outer Layer Copper  1oz~3oz(35um~105um)
The default thickness of the outer layer of copper foil on regular circuit boards is 1oz, up to 3oz.
Finished Inner Layer Copper 0.5oz(17um)
Default conventional circuit board inner layer copper foil line thickness is 0.5oz
Board Thickness 0.4~3.0mm 0.4/0.6/0.8/1.0/1.2/1.6/2.0/2.4/3.0 mm
Finished Board Thickness Tolerance Plate thickness ≧1.0mm, plate thickness tolerance ±10%.
Plate thickness <1.0mm, plate thickness tolerance ±0.1mm
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).
Multiple Printed Panel No gap splicing: 0 gap splicing
Gap splicing: 1.6mm gap splicing
The gap of the spliced boards should not be less than 1.6mm, otherwise it is more difficult to routing.
Multiple Printed Panel,V-cut Shipments Distance between wiring and solder pad to board edge: ≥ 0.4mm The line must be > 0.4mm spaced away from the edge, otherwise the V-cut will hurt the line and the pads
Single piece shipments Distance between wiring and solder pad to board edge: ≥ 0.2mm Single piece shipments need to have ≥0.2mm spacing, otherwise the lines and pads inside the board may be involved.
Drilled hole Drill/Hole Size(mechanical drilling) 0.2~6.3mm Min. drill size is 0.2mm, Max. drill size is 6.3mm, if greater than 6.3mm factory to be dealt with separately, mechanical drill specifications for the 0.05mm for the first order, such as 0.25, 0.3mm
Hole Size Tolerance(Mechanical Drilling) ±0.075mm Drilled holes with a tolerance of +/-0.075mm.
Eg. For the 0.6mm hole, the finished hole size between 0.52mm to 0.68mm is acceptable.
Minimum Borehole ID and OD Min.ID:0.2mm
Multilayer PCB:Min.ID:0.2mm,Max.OD:0.45mm
Double Layer PCB:Min.ID:0.2mm,Max.OD:0.45mm
Min Hole Size For Half-Hole Process ≥0.65mm Half-hole process is a special process, the min. hole size shall not <0.65mm,<0.65mm can not do the effect of half-hole
Through Hole Single Sideannular Ring 5mil
Circuit Trace Width Single&Double Layer PCB,multilayer PCB are 3.5mil.
Trace Spacing Single&Double Layer PCB,multilayer PCB are 4mil.
Pad Edge To Wire Edge Spacing 6mil
Min Character Width Conductor Width 4mil Character Height 27.5mil
Solder mask opening 0.05mm If need solder mask bridge, it should be more than 4MIL.
Not to soldermask bridge as the inspection and shipment standards.
Dimension Tolerance ±0.15mm Board profile tolerance ±0.15mm
Min. Strips 3mm
NOTE Pads Manufacturer Copper Layup Method Hatching
Outline Please use Outline to design if there are many non-plated (NPTH) holes.
