Base Material
FR-4 is the most commonly used material for PCBs. One sided aluminum boards have traces on one side and bare aluminium on the other. They are good for heat dissipation. For multi-layer aluminium PCBs please use the Advanced service. Flexible Printed Circuit boards (FPC) are much thinner than FR-4 and can be bent to some extent. Learn More

PCB Assembly

FREE Express shipping for PCBA

After assembly, each PCBA will undergo visual inspection to gauge assembly quality, e.g. solder joints and component placement. You will receive a report detailing the results of the inspection. This service comes free with all PCBA assembled in Fusion.

Please log in/create an account before uploading your file.

Functional testing is a paid service that verifies that the assembled device functions as intended as per the design. You will be asked to supply additional documents on how the PCBA is expected to perform. More information.

The contents of the file must be as shown.

  • We only recognize commas to distinguish the designator.
  • The designator should be ≤ Qty.
  • MPN is the Manufactured Part Number, NOT Digikey or Mouser Part Numer.
  • Do not include components in the BOM that you do not need us to solder onto the boards.
