PCB Fabrication
1. What is the producible copper thickness range for your PCB boards? +
We support a finished copper thickness range from 1/2oz (18µm) minimum to 30oz (1050µm) maximum, for both inner and outer layers of heavy copper PCBs.
2. What is the maximum number of PCB layers you can manufacture? +
We can manufacture PCBs with up to 32 layers, meeting the needs of high-complexity industrial and electronic designs.
3. What is the maximum PCB panel size you can produce? +
The maximum producible PCB panel size is 610mm x 610mm.
4. What is the producible finished board thickness range and tolerance? +
- Minimum finished board thickness: 0.15mm for 1-2 layer PCBs, 0.38mm for 4-layer PCBs
- Board thickness tolerance: ±0.1mm for board thickness <1.0mm; ±10% of board thickness for board thickness ≥1.0mm
- Note: The final finished board thickness includes copper thickness.
5. What is the minimum drill hole size you can produce? +
The minimum producible mechanical drill hole size is 0.1mm for standard PCB designs.
6. What PCB laminate brands do you commonly use? +
We use industry-leading PCB laminate brands including Shengyi, KB, ITEQ, and GDM, ensuring stable material quality and performance.
7. What is Tg value in PCB materials, and what Tg values can you produce? +
Tg (Glass Transition Temperature) is the temperature at which the PCB laminate transitions from a rigid glassy state to a flexible rubbery state, a key parameter for high-temperature applications.
We commonly produce boards with Tg130, Tg150, and Tg≥170, and can support high-Tg boards up to Tg260 for special high-temperature requirements.

8. What is the flame retardant rating of your PCB boards? +
Our standard FR4 PCB boards meet the UL94 V-0 flame retardant rating, the highest standard for commercial PCB materials.
9. What is solder mask, and what solder mask colors are available? +
Solder mask is a protective layer applied to the PCB surface to prevent solder bridging on non-pad areas, protect copper traces from oxidation, and provide electrical insulation.
Available solder mask colors: Green, Blue, Black, Red, White, Yellow, Purple.
Available solder mask colors: Green, Blue, Black, Red, White, Yellow, Purple.
10. What silk screen (legend) colors are available? +
Available silk screen (legend) colors: Green, Blue, Black, Red, White, Yellow, Purple, with white being the most commonly used for standard PCB designs.
11. What is the difference between single-ended impedance and differential impedance? +
- Single-ended impedance: Impedance control for a single transmission line, referenced to a ground plane, typically used for single-ended signal transmission.
- Differential impedance: Impedance control for a pair of complementary transmission lines, referenced to each other, typically used for high-speed differential signal transmission (e.g., USB, HDMI, Ethernet) to improve noise immunity and signal integrity.
12. What design file formats do you support for PCB manufacturing? +
We support standard PCB design file formats including Gerber RS-274X, ODB++, and native CAD files from Altium Designer, KiCad, and other mainstream EDA software. We can also generate Gerber files from your original design drawings upon request.
13. Do you have your own PCB manufacturing factory, or are you an OEM? +
We own and operate our own PCB manufacturing factory with full in-house production capabilities from PCB fabrication to assembly, ensuring full control over production quality, lead time, and cost. We also provide OEM services for customized PCB and PCBA projects.
14. What is your PCB manufacturing quality control process? +
We implement a full-process quality control system including incoming material inspection, in-process inspection for each production step, AOI (Automated Optical Inspection), electrical testing, and final visual inspection before shipment. All production processes comply with IPC international standards.
15. Can you produce PCBs meeting IPC Class 3 standards? What is the price difference from IPC Class 2? +
Yes, we can manufacture PCBs fully compliant with IPC Class 3 standards for high-reliability aerospace, medical, and industrial applications.
The price for IPC Class 3 PCBs is typically 15%-30% higher than IPC Class 2, due to stricter production tolerances, more rigorous inspection processes, and lower production yield.

16. Can you provide PCB mechanical structure layer design services? +
Yes, our engineering team can provide PCB mechanical structure layer design services, including board outline design, mounting hole layout, keep-out area definition, and 3D model matching for your enclosure design.
17. What payment methods do you support? Do you offer monthly credit terms? +
We support multiple payment methods including T/T bank transfer, PayPal, Western Union, and credit card payments.
Monthly credit terms are available for long-term cooperative customers with stable order volume, subject to credit review and approval.

18. Can you provide a detailed production schedule for my PCB order? +
Yes, we provide a detailed step-by-step production schedule for every order, including expected completion time for each production process, inspection stages, and final shipment date. We also provide real-time production progress updates upon request.
