FAQQ1: Do you provide OEM/ODM services for custom PCB and PCBA designs?
A: Yes, we offer full OEM/ODM services tailored to your Gerber files, BOM, and specific requirements.

Q2: What information do you need to provide a quotation?
A: Please send us your Gerber files (or PCB design files), BOM list (for PCBA orders), required quantity, and any special requirements such as surface finish or board thickness. The more details you provide, the faster and more accurate the quote.

Q3: Are my design files and BOM kept confidential?
A: Yes. All files and designs you share with us are kept strictly confidential and are never shared with third parties or used for any other customer's project.

Q4: What is your MOQ?
A: Highly flexible,we accept orders starting from 1 piece for prototypes, up to full mass production runs.

Q5: Do you offer PCB assembly (SMT/THT) services?
A: Yes, we provide complete turn-key solutions including component sourcing, assembly, and functional testing. Components are sourced according to your BOM after order confirmation, through our regular supplier channels.

Q6: How do you ensure product quality?
A: All laminates and raw materials are tested by independent third-party labs (SGS) and certified compliant with RoHS and REACH standards. Our production partners hold ISO 9001:2015 certification, and relevant assembly processes follow UL-recognized material standards. Every batch goes through SPI, AOI, X-Ray inspection, and Functional Testing before shipment — full inspection reports are available upon request.

Q7: How is shipping cost calculated?
A: Shipping cost depends on the destination, weight, and packing size of your order. Let us know your shipping address and we'll provide a freight quote along with your product quotation.Send us your Gerber files and BOM to get a fast quote — our team responds within 24 hours.
