Just a simple question:

the smallest anular ring on component hole is specified as 0.4mm/16mil.
Is this the value of (F-G) or of (F-G)/2?

Thanks in advance
Danilo

Hi Danilo,

that means: 0.2mm around for component holes.
Example: 0.8mm component hole - add copper around 0.4mm, so you need a pad of 1.2mm
