FR-4 PCB Capabilities
No. Item Manufacturing Capabilities Illustration
1 Material FR-4 (Fiberglass) For Rogers, Taconic, ARLON and other HDI boards, please contact PCBGOGO for details.
2 Number of Layers 1 Layer, 2 Layers, 4 Layers, 6 Layer, 8 Layers, 10 Layers
3 TG Grade TG130~140, TG150~160, TG170~180
4 Max PCB Size 1 layer & 2 layers: 1200*300mm or 600*500mm
Multi-layers: 600*500mm
5 Min PCB Size 5mm*5mm
6 Board Size Tolerance(Outline) ±0.2mm(CNC routing)
±0.5mm(V-scoring)
7 Surface Finish HASL with lead, HASL lead free, Immersion gold(ENIG), OSP, Hard gold, ENEPIG, Immersion silver (Ag), None
8 Board Thickness 1 Layer/2 Layers: 0.2~2.4mm
4 Layers: 0.4~2.4mm
6 Layers: 0.8~2.4mm
8 Layers: 1.0~2.4mm
10 Layers: 1.2~2.4mm

Note: Customized PCB thickness and Layer stackup are acceptable.
9 Board Thickness Tolerance Thickness≥1.0mm: ±10%
Thickness<1.0mm: ±0.1mm

Note: Normally “+ Tolerance” will occur due to PCB processing steps such as electroless copper, solder mask and other types of finish on the surface.
10 Outer Layer Copper Thickness 1oz/2oz/3oz
(35μm/70μm/105μm)

Note:
2oz
PCB thickness≥1.2mm,
Via size≥0.25mm,
Min Track/Spacing≥0.15mm

3oz
PCB thickness≥2.0mm,
Via size≥0.3mm,
Min Track/Spacing≥0.2mm
11 Inner Layer Copper Thickness 1oz/1.5oz
(35μm/50μm)
12 Outer layer Min track/spacing ≥3mil
13 Inner layer Min track/spacing ≥4mil
14 Annular Ring Size ≥0.13mm
15 Grid Line track/spacing ≥0.2mm
16 Coil board Line track/spacing ≥0.2mm
17 BGA pad size ≥0.25mm
18 BGA Distance ≥0.12mm
19 Board Outlines Track to Outline: ≥0.3mm
Trace to V-cut line: ≥0.4mm
20 Finished Hole Size Tolerance ±0.08mm
21 Finished Hole Diameter(CNC) 0.2mm~6.3mm
1. PCB Thickness=2.0mm, Min hole size is 0.3mm
2. PCB Thickness=2.4mm, Min hole size is 0.4mm
3. Copper Thickness=2OZ, Min hole size is 0.25mm
4. Copper Thickness=3OZ, Min hole size is 0.3mm
22 TH Via Distance Same nets: 0.15mm
Different net: 0.25mm
23 Plated Slot Size ≥0.5mm

Note:
L:W=2.5: 1 (Should be 2.5:1 or higher. If it is less than this, the holes may be misaligned.) If you can't draw a long hole in your design, you can draw a continuous round hole and it will be regarded as a long hole. Also, it is okay to draw the oblong hole in Profile Layer instead of Drilling Layer.
24 Castellated Holes ≥0.6mm
25 Non-Plated Holes ≥0.8mm
26 NPTH to Copper Line ≥0.2mm
27 Soldermask Green, Red, Yellow, White, Black, Blue, Purple, Matte Green,Matte Black,None
28 Soldermask Thickness 20~30um
29 Soldermask Bridge Green: ≥0.1mm
Others: ≥0.15mm
30 Soldermask to soldering pad distance ≥0.05mm
31 Silkscreen White, Black, Yellow, None
32 Minimum Character Width(Legend) ≥0.15mm

Note: Characters of less than 0.15mm wide will be too narrow to be identifiable.
33 Minimum Character Height (Legend) ≥0.75mm

Note: Characters of less than 0.8mm high will be too small to be recognizable.
34 Character Width to Height Ratio (Legend) 1: 5 (In PCB silkscreen legends processing, 1:5 is the most suitable ratio)
35 Silkscreen to Soldering Pad Distance ≥0.1mm
36 V-cut Line ≥70mm

Note:
PCB thickness≥0.6mm
Details refer to right side picture


37 V-cut Line Distance ≥3.5mm
38 Distance betwen Board to Board ≥0.8mm
39 Stamp-hole Width ≥2.0mm

Note: PCB size and thickness are subject to review by ITIS.
40 Tab-route Width ≥1.6mm

Note: PCB size and thickness are subject to review by ITIS.
41 Edge Rail ≥3.5mm

Note: If choosing panel by ITIS, we will add 5mm edge rails on both sides by default.
42 Gold Finger Bevelling Angle: 30~45°
