|---|---|---|---|
| Drill Diameter |
1-layer: 0.3 – 6.3 mm
2-layer: 0.15 – 6.3 mm Multilayer: 0.15 – 6.3 mm |
Holes with diameter ≥ 6.3 mm are CNC routed from a smaller drilled hole.
Min. drill diameter for 2- or more-layer PCBs is 0.15 mm (more costly) Min. drill diameter for aluminum-core PCBs is 0.65 mm Min. drill diameter for copper-core PCBs is 1.0 mm |
|
| Hole size Tolerance (Plated) |
Through-holes: +0.13 / -0.08 mm
Press-fit holes: ±0.05 mm (multilayer EMI boards only – mention the specific holes in PCB Remark) |
e.g. for the 0.6mm hole size, the finished hole size between 0.52mm to 0.73mm is acceptable.
|
|
| Hole size Tolerance (Non-Plated) |
±0.2mm
|
e.g. for the 1.00mm Non-Plated hole, the finished hole size between 0.80mm to 1.20mm is acceptable.
|
|
| Average Hole Plating Thickness |
18μm

| Blind/Buried Vias |
Not supported
|
Currently we don't support Blind/Buried Vias, only make through holes.
|
|
| Min. Via hole size/diameter |
0.15mm / 0.25mm
|
1-layer (NPTH only): 0.3 mm hole size / 0.5 mm via diameter
2-layer: 0.15mm hole size / 0.25mm via diameter Multilayer: 0.15 mm hole size / 0.25 mm via diameter ① Via diameter should be 0.1mm(0.15mm preferred) larger than Via hole size. ② Preferred Min. Via hole size: 0.2mm |
|
| Min. Non-plated holes |
0.50mm
|
Please draw NPTHs in the mechanical layer or keep out layer.
|
|
| Min. Plated Slots |
0.5mm
|
The minimum plated slot width is 0.5mm, which is drawn with a pad.
|
|
| Min. Non-Plated Slots |
1.0mm
|
The minimum Non-Plated Slot Width is 1.0mm, please draw the slot outline in the mechanical layer(GM1 or GKO)
|
|
| Via Hole-to-Hole Spacing |
0.2mm
|
|
|
| Pad Hole-to-Hole Spacing |
0.45mm
|
|
|
| Min. Castellated Holes |
0.60mm
|
Castellated holes are metalized half-holes on PCB edges, commonly used on daughter boards to be soldered onto carrier PCBs.
① Hole diameter (Ø): ≥ 0.6 mm ② Hole to board edge (L): ≥ 1 mm ③ Hole to hole (D): ≥ 0.6 mm ④ Min. PCB size: 10 × 10 mm ⑤ Min. PCB thickness: 0.6 mm |
|
| Plated Edges |
10 x 10mm
|
Plated edges are copper-plated and ENIG treated, HASL is not supported.
① Min. PCB size: 10 × 10 mm ② Min. PCB thickness: 0.6 mm ③ At least 3 breaks (more for larger PCBs) in the edge plating are required for support tab connections |
|
| Rectangular Holes / Slots |
Not supported
|
Rectangular holes and slots without rounded corners are not supported.
