Q1. What is needed for PCB/PCBA quotation?

A:PCB : Quantity, Gerber file and Technical requirements (material,board thickness,, copper thickness,surface finish treatment...)
PCBA: PCB information, BOM, (Testing documents...)

Q2. What file formats are accepted for bare board PCB fabrication?

A:Gerber formats RS274X and RS274D are preferred. The Gerber RS274D format will require a separate aperture list for each file.Depending on the complexity, we may also accept design files in ODB++ and DWG file formats.

Q3. Are my files safe?

A:Your files are held in complete safety and security.We protect the intellectual property for our customers in the whole process..All documents from customers are never shared with any third parties.

Q4. MOQ?


Q5.Shipping cost?

A:The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.

Q6.Can I have multiple orders shipped in one pachage?

A:Yes. Shipping multiple orders in one package will reduce your shipping costs. When placing your order through a sales rep,they'll automatically do their best to combine shipments when possible.

Q7. How do I track my order.

A: Your sales representative will provide tracking once your order has shipped.

Q8. How do I count the lead time?

A: The lead time schedule is as follows:

3 Day Lead Time   4 Day Lead Time   5 Day Lead Time
Order Date Ship Date   Order Date Ship Date   Order Date Ship Date
Monday Thursday   Monday Friday   Monday Next Monday
Tuesday Friday   Tuesday Next Monday   Tuesday Next Tuesday
Wednesday Next Monday   Wednesday Next Tuesday   Wednesday Next Wednesday
Thursday Next Tuesday   Thursday Next Wednesday   Thursday Next Thursday

Below is our standard lead time matrix which we can offer in normal circumstances. Please contact our team to confirm if we can meet your lead time.

Order Type Size (sq/m) Best Lead Time (WDS) Standard Lead Time (WDS)
NPI/Prototype 0 – 1 1, 3, 5, 7 15
HMLV (High Mix Low Volume) 1 – 15 5, 7, 10 15
Production – Small 15 – 100 5, 7, 10 15 – 20
Production – Medium 100 – 300 7, 10 18 – 25
Production – High >300 15 25 – 30


All lead times are in manufacturing working days (WDS) and do not consider freight. Actual lead times might vary based on the availability of raw material and the specifications of the part. Due to the production cycle times, not all technologies can achieve the presented WDS.
