FAQ : 

Q1: How can you guarantee quality while your price is so low?
--- Location: Our marketing office located in Shenzhen, but mass production factory moved to JiangXi province (near by SZ) which has lower electricity, water and labor. And factory are self-built, no house rent.

--- Yes we can offer sample,  but you have to pay first, once you do mass production from us, the sample fee will pay back to your account!  I believe we can do long term business!

Q4: Can you manufacture my PCBs from a picture file? ---No, we cannot accept BMP, GIF, TIFF, or JPG pictures as the manufacturing file as these formats are not good for PCB manufacturing. But you can use these files to request a quotation. If you do not have gerber file, you can send us sample to copy it.

Q5: Do you have pcb in stock?
--- No. Our pcb board are custom-made product, all produced depends on clients gerber file.

--- No, we cannot accept BMP, GIF, TIFF, or JPG pictures as the manufacturing file as these formats are not good for PCB manufacturing. But you can use these files to request a quotation. Or send us sample to copy.

Q8: What do you require in order to produce an assembly quotation?
--- Bill of materials (BOM) detailing the components to be fitted to the PCB with the manufacturers parts numbers and the components suppliers' parts number (e.g. Digi-key, Mouser, RS ). PCBA sample photos if possible. By allowing us to see the product pictures it will help us to give you the quotation faster. In addition to the above, we would need details of approximate order quantity.

Q9: Will my PCB files be checked? ---Yes. Your data will be checked with our design rule check. If we find any technical issues or have any enquires we will contact you. This is quite common for prototype orders. Please keep an eye on your email in the first 12 hours after placing your order.

Q10: Can I order a PCB with a non-rectangular shape? ---Yes, you can, we accept any PCB shape. Note that a rectangular outline (the minimum rectangular shape which can cover the entire PCB) will be used to calculate the board size. The shape should be clearly indicated in at least one of your copper layers. Otherwise you must supply a mechanical plan, separate from the Gerber file, indicating the shape of the PCB. This file has to have a reference to the copper layers, or has to have the same offset as the other layers.

Q11: Does XJY Company bevel gold fingers? ---Yes. A standard 45-degree bevel will be added to your edge connector. At your request, we can also bevel at 15 or 30 degrees upon request. For multi-layer boards please ensure you have adequate back set for the bevels. Please mention this in the order form when placing your order.

Q12: My assembly company need the PCBs as panelized, can you do this for me? ---Yes. We can panelize your circuits upon your request.
