Maximum PCB Size
(Dimension)

1300*600mm

For any sizes beyond this dimension, please view the below "Standard PCB" or contact sales re

Board Size Tolerance
(Outline)

±0.15mm

+/-0.13mm

±0.15mm for CNC routing, and ±0.2mm for V-scoring.

Board Thickness

0.6-2.0mm

0.4-3.0mm

0.6-3mm， Please contact us if your board exceeds these.

Board Thickness
Tolerance(t≥1.0mm)

±10%

+/-8%

Normally “+ Tolerance” will occur due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface.

Board Thickness
Tolerance(t<1.0mm)

±0.1mm

+/-0.08mm

Min Trace

0.2mm

0.15mm

Min manufacturable trace is 5.9mil(0.15mm), strongly suggest designing trace above 8mil(0.2mm) to save cost.

Min Spacing

0.2mm

0.15mm

Min manufacturable spacing is 5.9mil(0.15mm), strongly suggest designing spacing above 8mil(0.2mm) to save cost.

Outer Layer Copper Thickness

1/2-3oz

1/2-6oz

Also known as copper weight. 35μm=1oz.70um=2oz，105um=3oz。 Please contact us if you need copper weight greater than 6oz.

Inner Layer Copper Thickness

1/2-3oz

1/2-6oz

Please contact us if you need copper weight greater than 6oz.

Drill Sizes (CNC)

1.0-6.0mm

0.8-6.5mm

Min drill size is 0.8mm, max drill is 6.0mm. Any holes greater than 6.0mm or smaller than 0.3mm will be subject to extra charges.

Min Width of Annular Ring

0.3mm

0.2mm

For pads with vias in the middle, Min width for Annular Ring is 0.1mm(4mil).

Finished Hole Diameter (CNC)

1.0mm

0.8mm

The finished hole diameter will be smaller than size of drill bits because of copper plating in the hole barrels

Finished Hole Size Tolerance(CNC)

±0.1 mm

+/-0.075mm

min±0.075mm
For example, if the drill size is 0.6mm, the finished hole diameter ranges from 0.525mm to 0.675mm will be considered acceptable.

Solder Mask(type)

LPI

UV

Liquid Photo-Imageable is mostly adopted. Thermosetting Ink is used in inexpensive paper-based boards.

Minimum Character Width(Legend)

0.2mm

0.15mm

Characters of less than 0.15mm wide will be too narrow to be identifiable.

Minimum Character Height (Legend)

0.8

0.8

Characters of less than 0.8mm high will be too small to be recognizable.

Character Width to Height Ratio (Legend)

4:1

5.3:1

In PCB silkscreen legends processing, 1:5.3 is the most suitable  ratio

Minimum Diameter of Plated Half Holes

0.5

Design Half-Holes greater than 0.5mm to ensure a better connection between boards.

Surface Finishing

HASL（1-40um）
HASL LF（1-40um）
Immersion Au (1-5u"),
OSP(0.12um minimum)
Immersion Tin(1um minimum)
Immersion Ag(0.12um minimum)
Hard gold (2-80u")
Flash gold(1-5u")
ENG+OSP
etc.

The most popular three types of PCB surface finish.

Solder Mask(color)

White, Black, yellow，green，blue,
grey, red, purple, and matt color

Silkscreen(color)

White, Black, yellow，green，blue
grey,red,purple

Panelization

V-scoring, Tab-routing, Tab-routing with Perforation (Stamp Holes)

Leave min clearance of 1.0mm between boards for break-routing. For V-score penalization, set the space between boards to zero.
