Flex PCB Capabilities

Number of Layers

0-4L

0-6L

For orders above 6 layers, please contact our sales rep.

Material

Polyimide

PET

For example：Dupont, shengyi, Taiflex, Iteq, etc.

Maximum PCB Size
(Dimension)

480*480mm

1200*480mm

Raw material width is only two types 250/500mm，

penalization should be based on the above two sizes,

for any sizes beyond this dimension, please contact sales.

Board Size Tolerance
(Outline)

±0.10mm for punching

+/-0.05mm fo

r laser cutting

±0.05mm for laser routing, and ±0.1mm for Die punching.

Board Thickness

0.05-0.3mm

0.05-0.75mm

0.05-0.75mm. Please view the below "Standard PCB" or contact us if your board exceeds these.

Board Thickness
Tolerance

±0.05mm

±0.03mm

min±0.03mm

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

Min Trace

3mil

1mil

Min manufacturable trace is 1mil(0.025mm), strongly suggest designing trace above 3mil(0.0.75mm) to save cost.

Min Spacing

3mil

1mil

Min manufacturable spacing is 1mil(0.025mm), strongly suggest designing spacing above 3mil(0.0.75mm) to save cost.

Outer Layer

Copper Thickness

1/3-2oz

1/3-3oz

Also known as copper weight. 35μm=1oz. Please view the below "Standard PCB" or contact us if you need copper weight greater than 3oz.

Inner Layer

Copper Thickness

1/3-2oz

1/3-3oz

Inner copper weight as per customer's request for 4 and 6 layers(Multi-layer laminated structure). Please contact us if you need copper weight greater than 3oz.

Drill Sizes (CNC)

0.2-6.0mm

0.1-6.5mm

Min drill size is 0.1mm, max drill is 6.5mm. Any holes greater than 6.5mm or smaller than 0.3mm will be subject to extra charges.

Min Width of

Annular Ring

0.15mm

0.1mm

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

Finished Hole

Diameter (CNC)

0.05-6.0mm

0.05-6.5mm

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

Finished Hole Size

Tolerance(CNC)

+/-0.076mm

+/-0.05mm

min±0.05mm

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)

coverlay

LPI solder

mask ink

Liquid Photo-Imageable is mostly adopted.

Minimum Character

Width(Legend)

0.2mm

0.127mm

Characters of less than 0.127mm wide will be too narrow to be identifiable.

Minimum Character

Height (Legend)

0.8mm

0.71mm

Characters of less than 0.71mm high will be too small to be recognizable.

Character Width to

Height Ratio (Legend)

4:01

5.6:1

In PCB silkscreen legends processing, 1:5.6 is the most suitable  ratio

Minimum Diameter

of Plated Half Holes

0.5mm

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

Surface Finishing

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 two types of PCB surface finish. Immersion Au (1-5u"), OSP(0.12um minimum)

coverlay(color)

White, Black, yellow

Solder Mask(color)

White, Black, yellow，
green，and matt color

Silkscreen(color)

White, Black, yellow，

green,blue,grey,red,

purple

Panelization(type)

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.
