Purchase Notice

Actual conditions are subject to confirmation with customer service.

Regarding Returns and Exchanges
As PCBs are custom products, returns are not supported. For quality issues, please contact customer service for a refund or replacement, but we do not bear any losses or costs beyond the product value. Delays in delivery due to force majeure factors such as power outages or water supply interruptions will not be compensated.
Regarding Orders
If there are any issues or special instructions, please communicate directly with customer service for confirmation. Do not leave messages, as we will not be responsible for any missed messages. Before and after payment, please confirm the process, quantity, and layers with customer service. Problems that arise after production or shipment will not be eligible for refunds. Since this product requires a high level of expertise, if the purchasing personnel are not knowledgeable, please confirm with your engineer or customer service. We will not be responsible for any issues caused by the customer's lack of understanding.
Delivery Time Calculation
Orders placed before 17:00 are considered as placed on the same day; orders placed after 17:00 are considered as placed the next day. "24-hour delivery" refers to one day, not 24 hours. The delivery time provided by customer service and on the page does not include Sundays or holidays.

Frequently Asked Questions

Q1: What types of printed circuit boards (PCBs) can you manufacture?

We manufacture a wide range of PCBs, including high-density multilayer boards (1-68 layers), impedance boards, high-frequency boards, high TG thick copper foil boards, 5G high-speed boards, buried blind via boards, aluminum-based boards, hybrid dielectric boards, HDI, rigid-flex boards, and other specialty customized solutions.

Q2: What is the typical lead time for PCB samples and mass production?

Lead times depend on the layer count. For 2-layer PCBs, the shortest sample lead time is 24 hours, with standard delivery in 3 days, and mass production in 6-7 days. For multilayer PCBs (4-18+ layers), samples range from 36 hours to 7 days, and mass production takes between 8 and 18 days.

Q3: Which design file formats do you accept for engineering reviews?

We accept standard industry formats, including RS-274-X and RS-274-D (Gerber formats), CAD, DXP, Protel 99 SE, PADS, and GC-CAM files.

Q4: What quality standards and certifications do your processes follow?

Our manufacturing processes strictly conform to quality management systems certified by UL, ISO9001:2015, ISO14001:2015, CQC, and IATF16949:2016. Shipping acceptance criteria follow customer requirements and IPC standards.

Q5: Can I return or exchange custom-made PCB orders?

Because PCBs are custom-manufactured products, standard returns and exchanges are not supported. For quality-related issues, please contact customer service immediately for a refund or replacement support. Compensation does not cover losses beyond the product value.

Q6: What shipping options are available for orders?

We provide several shipping options based on customer preference: Air express delivery (UPS, DHL, TNT, CTS, and FEDEX), railway freight, seaborne shipping, or any other customer-designated shipping carrier.
