Minimum Data/Information Requirements to Place Order

Scope: The purpose of this document is to describe the minimum data and information required by Epec Engineering to generate the tooling.

General: The minimum required data and information set can be broken down into two categories: “Board Data” and “Fabrication Instructions”.

1. Board Data:

Board data can consist of the traditional data package which must include the following:

  • Gerber Data in the following formats:
    • 274D including separate aperture list with all apertures defined.
    • 274X
  • Drill Data in the following formats:
    • Excellon 1
    • Excellon 2

Also acceptable is ODB++ data. ODB++ will be supplied as a single file, usually with the extension of .tgz. ODB++ contains all the required board and drill information.

Note: Any other data formats need to be reviewed and approved by Epec Engineering before the order can be placed.

2. Fabrication instructions:

The fabrication instructions should contain all relevant information required to tool and build the part including:

  • Hole sizes with tolerances, and plating information
  • Board outline detail with all required dimensions and tolerances
  • Hole or feature to edge dimensions
  • Board thickness with tolerances, and measurement criteria
  • Surface finish information
  • Soldermask requirements
  • Silkscreen requirements
  • Technical contact information
  • Any additional requirements (i.e. impedance, controlled dielectrics, carbon ink, etc.)

The fabrication instructions may be found:

  • Fabrication Drawing:
    • Adobe Acrobat (.pdf)
    • Gerber
    • HPGL
    • AutoCAD (.dwg or .dxf)
    • Graphic file (.jpg, .gif, .tif, etc…)
    • ODB++
  • Notes, readme files, and/or customer specification
