***It is extremely important that all jobs should include a "Aperture List (*.APR) File" in text format.

Mandatory files needed per board assignment:

When adding in hidden/blind vias, these can only be between certain layers. Please see the Hidden/Blind Vias section for more information.

We accept data in the following formats:

            ODB++  PREFERRED DATA ACCEPTED
           
GerberX (RS 274-X) PREFERRED DATA ACCEPTED
           
Gerber
            HP-GL
            Excellon
            Sieb & Meier
            DXF
            DPF (Barco)
 

Recommended file names and extensions for those who are not familiar with conventional nomenclatures.        

Single sided PCB:

                             *.top (top layer)

*.ncd (NC Drill file, plated)

*.brd (board outline)

 

                        Optional files for single layer:

                                      *.tsk (text top layer)

*.tmk (top solder mask)

*.slt (slot outline)

*.bot (bottom layer)

*.bmk (bottom solder mask)

*.bsk (bottom text layer)

 

 

            Double (two layer) Sided PCB: 

                             *.top (top layer)

*.bot (bottom layer)

*.ncd (NC Drill file, plated)

*.brd (board outline)

 

                        Optional files for double layer:

                                      *.tsk (text top layer)

*.tmk (top solder mask)
