In assembly drawing, the components reference designators, rotations, component land pads must be specified. All special requirements for component mounting must be specified.  

BOM (Bill of materials)

Assembly aside, in the BOM file all required components reference designators, quantities, manufacturer part numbers and IC markings must be specified. We also need a revision and their change log (history) for documentation.

Additional information

  • PCB data. We prefer Gerber RS-274-X format. Solder paste layer must be included in gerber files. Requirement for PCB should be specified in text file or in gerber files. If electrical, impedance or other test are needed, this must be specified.
  • If programming/testing is needed, please provide detailed procedures for these operations.
  • If IPC-A-610C 3 is needed, this also must be specified. By default, Esemda is using IPC-A-610C class 2 for assembly quality control.
  • If possible, please add photos of fully assembled product or a real sample.
