Q: How to Get a Quotation for PCB ?
A: Please send your PCB gerber files or files like “.pcb”, ”.pcbdoc”, “.lay”, “.lay6”, “.brd”,”.dip” to service@zfpcba.com
with your order quantity, shipping country and indication of related technical requirements as well as any special requirement if you have.
If you do not have the file in the correct format, you can send all the details related to the products.
Q: How to Get a Quotation for PCBA (Assembly PCB) ?
A: Please send BOM(Bill of Material/Components) and above mentioned PCB files. It’s better if you could supply finished production photos and full requirement detail images.
Q: How to Get a Quotation for SMT Stencil ?
A: Please send above mentioned PCB files. We are able to make stencil files directly according to your PCB layout files.
Q: What is PCB Gerber file?
A:The PCB Gerber format is an open 2D binary vector image file format. It is the standard file used by printed circuit board (PCB) industry software to describe the printed circuit board images: copper layers, solder mask, legend, etc. PCB Gerber files should be inside a .rar or.zip archive with standard file extensions:
Extension                                Layer
pcb name.GTL                        Top Layer Copper
pcb name.GTS                        Top Solder mask
pcb name.GTO                       Top Silkscreen
pcb name.GBL                        Bottom Layer Copper
pcb name.GBS                        Bottom Solder mask:
pcb name.GBO                       Bottom Silkscreen:
pcb name.TXT                        Drills
pcb name.GML/GKO           Board Outline
4 layer board also need
pcb name.GL2                     Inner Layer2
pcb name.GL3                     Inner Layer3
Notes: PCB Gerber file must be RS-274X format. Drill file(pcb name.TXT) should be Excellon format.
Q:What’s the BOM?
A: BOM is a Bill of Materials that list the components required to build your project.  BOM’s include part number, brand, reference designator , quantity, and description of parts that need to be assembled. 
Q: What will need for PCB clone service ?
A: Please send us the printed circuit board concerned,and also the sharp photos of its front side and the back side.
Q:How long does it take for PCB and assembly quote?
A: Normally 24 hours as soon as receive internal engineer evaluate confirmation.
Q:What’s the minimum order quantity (MOQ) requirement?
A: No, we do not have MOQ requirement, we can support your projects starting from prototypes to mass productions.
Q: What’s the shipping way ?
A: We could choose express normal 3-5day quick delivery.(DHL, Fedex, UPS, EMS etc.) Also choose Air or Sea for mass order delivery. Also you can specify a shipping way.
