You should always consider the following rule when designing your data: Pad Ø = Finished Ø + 0,35mm
For the nomenclature:
If the annular ring in your layout does not conform to our specification then we will adjust the finished hole size or the pad diameter. As a result of this the price can increase.
Our advice: During the design of your PCB data consider the following rule of thumb: Pad diameter = finished hole diameter + 0.35mm
