POE PCB Manufacturing FAQ
1. Are my PCB Design Files safe when submitting them to you for manufacturing?
We respect customer's copyright and will never manufacture PCBs for someone else with your files unless we receive written
permission from you, nor we'll share these files with any other 3rd parties. At your request, we can sign an NDA for extra security.
2. Do you handle Prototype PCBs or Small Volume PCB production orders?
Yes, we can manufacture PCBs in any volume. MOQ =1pcs
3. What is your minimum order quantity?
One piece, or one PCB Panel
1. Can we negotiate on my price?
Even though our pricing is very low, you can still discuss price with us to meet your target in cost reduction, as demanded by the
2. What are the Factors Affecting PCB Cost?
1. The quantity and size of the PCB;
2. The Number of Layers;
3. Effective Panelization - Some board sizes and shapes can offer up to 80% Usable Panel Area, with very few "dead spaces", while others some down to 50%. This would affect your price;
4. Number of holes the boards is drilled on sophisticated NC drilling machines. These machines are quite expensive and the machine time is expensive too, so less holes means less machine time for drilling and lower cost;
5. Number of Hole Sizes - the slowest operation in drilling is the tool exchange. Usually the boards are drilled at very high RPM values, up to 60-80.000 rpm. To change the tool, the machine has to stop the spindle, so we must wait until the tool stops rotating. Once the drill action has stopped, the machine must move to the drilling rack, replace the old tool, get new tool, move back to board drill position, drive the spindle again, and wait for the RPM value to reach the set point for the new tool. Each tool change takes approximately the same time as drilling 100-200 holes. Try to minimize the number of drill tools as much as possible. It is best to standardize any holes with diameter differences of only a few mils, if the change will pass your required tolerances;
6. PCB Laminate Material - when you intend to manufacture your board in volume, the right choice for the board laminate can save a lot of money. For instance despite the superior characteristics of FR-4, all consumer electronics today still is manufactured on old paper FR-2 laminates as they cost two times less expensive than FR-4;
7. Trace Width / Part Spacing requirements – these characteristics are in close relation to the manufacturing yield. For instance, if your traces are wide enough (>20mils) the board can be manufactured with etch resist single silkscreen printing operation instead of dry film lamination, exposure, developing;
8. Special board requirements, Controlled Impedances, Via in Pad, Blind / Buried Vias, Microvias, etc. – again, these
requirements affect the manufacturing yield;
4. Can I order my board with PCB Silkscreen on top and bottom?
Yes, we offer full silkscreen as one of our Standard Cost PCB Options, at no additional charge.
5. May I have overlapping drills on my board?
1. What is your standard laminate thickness?
Our standard laminate thickness is 1.6 mm (0.063");
2. What other Laminate Thickness Options do I have?
0.3mm, 0.4mm 0.6mm 0.8mm 1.0mm 1.2mm 2.0mm 2,4mm ,3.0mm 3.2mm 4mm, 6mm;
3. Can you manufacture on High Frequency PCB Materials, such as Rogers, etc?
Yes, we can;
4. Can you tell me more about your laminates physical properties?
Yes, we can;
1. What copper thickness option do I have?
We can offer 0.5 oz, 1.0 oz, 1.5 oz, 2.0 oz, 2.5 oz, 3.0 oz, and Heavy Copper PCB options at 3.5 oz, 4.0 oz, 4.5 oz, and 5.0 oz;
1. What kind of file format can you accept?
We can process Gerber RS-274X and ODB++ files;
2. Can you manufacture my board from this: BMP, GIF, TIFF, JPG picture?
No, as these formats do not translate to our PCB Fabrication machinery;
1. What Solder Mask do you use for production?
We use green Liquid Photo Imageable (LPI) Solder mask for our PCB production;
2. Does solder mask increase your prices?
No, the solder mask is standard option for our prototypes, so all boards are produced with solder mask and this doesn't increase
3. What Solder Mask Colors are available for my PCBs?
Green, black, blue, red, yellow and white solder masks;
PCB SURFACE FINISH
1. What surface finish can I have?
HASL, Immersion Gold, Immersion Tin, Immersion Silver, OSP, Hard Gold, and Soft Gold, and more;
1. What Design Files Are Necessary for PCB Manufacturing & Assembly?
POE is focused on Turnkey services. For a turnkey order, we will require a bill of materials (BOM), and of course your board
designs in either Gerber or ODB++ format. In addition,Fabrication or assembly drawings, or any special instructions specific to
the project. If your design is not fully completed, we do provide preliminary quotes based on early gerber files. We have
provided further details on generating these files below;
A drill file contains the location and size of all drill holes. There may be multiple files if blind/ buried vias are required. Please be
sure to include all drill files to ensure none of your requirements are missed;
Mechanical files should also be included with your file set. For example, the board outline file is used for verifying the dimension
of the board. You may also want to include any cut-outs or internal routing on this layer;
We also accept ODB++ file in lieu of Gerber files. These files are typically generated in an archive and include all
fabrication files together.
"Pick and Place" or “XY Coordinate” file: contains information about where each component is placed on the board, such as the x-y position, rotation, layer, reference designator and the value/package.
Bill of Materials (BOM)
The BOM is a list of all the parts that will be populated on the board. These also include the parts that are DNI. See our SAMPLE;
If your board contains any special requirements such as impedance control, gold fingers, blind/buried via, unique stack up/
thickness, etc., please include a document outlining your requirements. These requirements are commonly listed in “ReadMe”
text files or “PDF” files.
An assembly drawing is helpful when there is not enough space for all reference designators on the board. A document
containing the assembly information of your board is most commonly sent as a “PDF” file.
If you are still working to finalize your design, we can typically generate a preliminary quote based on early Gerber files, or a
detailed description. When you have finalized your design, we will review any updated files and modify your quote accordingly.
If you need any additional information regarding data requirements, please email firstname.lastname@example.org and one of our
specialists will get in touch with you.
2. Who will be responsible for the customs duty at my country?
As POE fabricate your PCBs in our facilities in Shenzhen China, we ship internationally to your country. As the customs policy in
different countries may differ, some customs authorities in some countries may levy customs duty on imported PCBs. If this
happens, it is your responsibility to pay. In many countries, the duty may be waived or exempted.
3. Do you sign NDA ?
