Below is a detailed overview of our manufacturing capabilities:
| Items | Manufacturing Capabilities | Remarks |
|---|---|---|
Number of Layers | 1-10 layers | For orders above 10 layers, contact our sales team. |
Material | FR-4, Aluminum | For Rigid, Rigid-Flex, Flex, Metal-based, Halogen-free, HDI, High Tg, etc., contact us. |
Maximum PCB Size | 500 x 1100 mm (min 5 x 6 mm) | For sizes beyond this, contact our sales team. |
Board Size Tolerance | ±0.2 mm / ±0.5 mm | ±0.2 mm for CNC routing, and ±0.5mm for V-scoring. |
Board Thickness | 0.2 to 2.4 mm (0.2 mm increments) | For thickness outside this range, contact us. |
Tolerance of Board Thickness | ±10% (t ≥ 1.0 mm) / ±0.1 mm (t < 1.0 mm) | Tolerance accounts for processes like electroless copper plating and solder mask application. |
Min Trace | 0.1 mm (4 mil) | We recommend designing traces above 0.15 mm (6 mil) to reduce costs. |
Min Spacing | 0.1 mm (4 mil) | We recommend designing spacing above 0.15 mm (6 mil) to reduce costs. |
Outer Layer Copper Thickness | 1 oz (35 μm), 2 oz (70 μm), 3 oz (105 μm) | Contact us for copper weights above 3 oz. |
Inner Layer Copper Thickness | 1 oz (35 μm), 1.5 oz (50 μm) | Contact us for copper weights above 1.5 oz. |
Drill Sizes (CNC) | 0.2-6.3 mm | Extra charges apply for holes smaller than 0.3 mm or larger than 6.3 mm. |
Min Width of Annular Ring | 0.15 mm (6 mil) | For pads with vias in the middle, Min width for Annular Ring is 0.15 mm (6 mil). |
Finished Hole Diameter | 0.2-6.2 mm | Finished hole diameter is smaller than the drill size due to copper plating. |
Finished Hole Size Tolerance(CNC) | ±0.08 mm | For example, if the drill size is 0.6 mm, the finished hole diameters ranging from 0.52 mm to 0.68 mm are acceptable. |
Solder Mask | LPI (Liquid Photo-Imageable) | Thermosetting ink is used for cost-effective paper-based boards. |
Legend Minimum Character Width | 0.15 mm | Characters narrower than 0.15 mm may not be identifiable. |
Legend Minimum Character Height | 0.8 mm | Characters shorter than 0.8 mm may not be recognizable. |
Legend Width-to-Height Ratio | 1:5 | This ratio ensures optimal silkscreen processing. |
Minimum Diameter of Plated Half Holes | 0.6 mm | Ensures better board-to-board connections. |
Surface Finishes | HASL (lead/lead-free), OSP, Immersion Gold | Contact us for other finishes. |
Solder Mask Colors | Green, Red, Yellow, Blue, Black, White | No extra charge for Green, Red, Yellow, and Blue. |
Silkscreen Colors | Black, White, None | No extra charge for silkscreen. |
Panelization | Tab-routing, perforation holes (Stamp Holes), V-scoring | Leave 1.6 mm clearance for break-routing; zero spacing for V-scoring. |
Testing and Certifications | Fly Probe Testing (Free), A.O.I. Testing (Free), ISO 9001:2015, IATF 16949, UL Certificate | No extra charges for testing. |

The most widely used material is FR4, a glass-reinforced epoxy. Other options include metal core PCBs (aluminum/copper) for heat management, polyimide for flexibility, and ceramic PCBs for high-frequency applications.
Layers are etched, stacked, and laminated under heat and pressure. Plated vias are then created to establish electrical connections between layers.
Quality is ensured through optical and X-ray inspection, flying probe testing for electrical continuity, and in-circuit testing (ICT) to verify functionality.
Impedance control ensures signal integrity, minimizes interference, and prevents signal loss, making it crucial for high-speed digital and RF circuits.
X-ray inspection detects hidden defects in solder joints, BGA components, and multilayer connections, ensuring reliability and performance.
