10 Fundamentals for Quality Data Outputs

10 Fundamentals for Quality Data Outputs

 

Here are 10 simple guidelines to keep in mind to avoid delays due to data issues when placing your order.

 

#1 – Do not scale your data. All data provided must be scale 1/1 (100 %).

#2 – Make sure that your data DO NOT contain zero apertures (size =0.00 mm or inches).

#3 – Use the same offset for all your Gerber layers and the Excellon drill data. Preferably use no offset at all.

 

#4 – Use the same units (mm or inch) in your Gerber & Excellon output files as in your CAD PCB design software to eliminate conversion or rounding errors.

#5 – Use the same resolution (grid) for your Gerber & Excellon data to allow a perfect match.

#6 – Make sure that your data is supplied as seen from top to bottom through the PCB. DO NOT mirror (or reflect) any data layer – image or drill. Viewing a PCB from top to bottom through the board is the universal practice in the PCB industry.

#7 – Put some small text (board identification, company name, etc…) in the copper layers.

#8 – In your Gerber files use flashed pads wherever possible.

#9 – In your CAD PCB design software try to create an aperture list for Gerber output which only shows the apertures that are used in the design.

#10 – It is a good practice to include the board outline on all layers. This will enable CAM operators to effortlessly identify any alignment disparities. Also include the board outline in a separate Gerber mechanical plan.
