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. | |

Via size≥0.3mm, Min Track/Spacing≥0.2mm 4oz via size>=0.3mm min track/spacing>=0.3mm 5oz via size>=0.3mm min track/spacing>=0.35mm | |
11 | Inner Layer Copper Thickness | 1oz/2oz/3oz (35μm/70μm/105um) | |
12 | Outer layer Min track/spacing | ≥3mil | |

20 | Finished Hole Size Tolerance | ±0.08mm | |
21 | Finished Hole Diameter(CNC) | 0.15mm~6.3mm
2. PCB Thickness=2.4mm, Min hole size is 0.3mm 3. Copper Thickness=2OZ, Min hole size is 0.25mm 4. Copper Thickness=3OZ, Min hole size is 0.3m | |
22 | TH Via Distance | Same nets: 0.15mm Different net: 0.25m | |
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 | ≥0.5mm | |
25 | Non-Plated Holes | ≥0.2mm | |
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: ≥0.15m | |
30 | Soldermask to soldering pad distance | ≥0.05mm | |
31 | Silkscreen | White, Black, Yellow, None | |
32 | Minimum Character Width(Legend) | ≥0.13mm
Note: Characters of less than 0.13mm wide will be too narrow to be identifiable | |
33 | Minimum Character Height (Legend) | ≥0.7mm
Note: Characters of less than 0.7mm high will be too small to be recognizable | |
34 | Character Width to Height Ratio (Legend) | 1: 6 (In PCB silkscreen legends processing, 1:6 is the most suitable ratio) | |
35 | Silkscreen to Soldering Pad Distance | ≥0.1mm | |
36 | V-cut Line | ≥70mm
Note: PCB thickness≥0.5mm 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 JH PCBA. | |
