Files Requirements

Please combine the following files into a single ZIP file. Upload the file from the Quote Summary Page or email it to Make sure you put your order number in the subject field. Eg.: "Files for order AE######".

1. Bill Of Materials (BOM)
We can accept your BOM in a number of formats but we recommend that you use PCB Assembly Express BOM when building your BOM. Please be sure to set the 'Type' field to to the correct value and use DNS (do not stuff) for any components we will not be placing. Your BOM should include:

  • Quantity of each part
  • Reference designator
  • Part number (Digi-Key, Mouser, Newark part numbers are okay)
  • Part description
  • Package description (QFN32, SOIC, 0805, etc. package is very helpful but not required).
  • Type (SMT, Thru-Hole, Fine-pitch, BGA, etc.).
2. Gerbers
Please include all gerber files. At a minimum we need top and bottom silkscreen, copper and the solder paste layers.

3. Centroid
It should include component locations, rotations and reference designators.

Review your Order & Send us your parts

  1. Print out the PCB Assembly Express label sheet. There is a link to it on your My Account Page and in the confirmation email you received. This label has our address and your order number pre-printed, as well as all the component labels.
  2. If there are locations on your printed circuit boards that you do not want populated please make sure they are all marked DNS (Do Not Stuff) in the 'Type' field of the BOM.
  3. If you have changed anything since you submitted your files please send your updated files to
  4. If there are special instructions for this build please include all the details including assembly drawings or images where applicable.
  5. If there are electronics components or circuit boards coming from other locations please let us know each of the locations.
  6. Ship the package(s) to us using the pre-printed shipping labels.
If there are parts from more than one order in the package be sure to segregate and clearly label them with the appropriate order numbers. If parts or boards are being drop-shipped from another company, make sure they put your PCB Assembly Express order number on the packing slip.

If possible, keep your parts in the anti-static packaging and moisture-proof packaging that they came in (don't tape the parts strips to anything).

Make sure all of your parts are clearly labeled and that the labels match what you put in the BOM that you emailed to us. Using the supplied parts labels helps to ensure we get the right parts in the right places.

Our Assembly Process

There are a number of tasks that we must complete after you place your kitted PCB assembly order. These tasks include:

  1. Confirm the necessary files and order details.
  2. Order and receive the SMT paste stencil if necessary.
  3. Program our machines from the BOM and Centroid file, before the materials arrive.
  4. Materials are received in. Materials are audited before your job is run.
  5. If all materials are in before noon, the assembly clock starts that day. If after noon, the clock starts the next day.
  6. A SMT stencil and stencil printer are used to mechanically apply the paste.
  7. An automatic pick and place machine place the SMT components.
  8. A SMT reflow oven is used to reflow the solder onto the SMT components.
  9. BGA components are X-rayed to verify placement accuracy and to detect any solder bridges.
  10. Thru-hole parts are inserted by hand. They may also be wave soldered depending on the board layout.
  11. A final quality check is performed.
  12. The finished PC board assemblies and all extra materials are shipped back to you.
