About Degassing Hole

FormerMember
FormerMember over 5 years ago

I use "Degassing" function in APD. It provides the options "Even Layers" and "Odd Layers". 

My first question is that is there any additional setting to choose the specific layer? 

The second question is that  is there any way to select a range to place degassing hoe? I don't want to place holes at the whole layer.

Thanks!

    i usually use a layer called "route keepout" for degassing holes.

    by placing degassing holes (circled shapes) on the route keepout manually, you can control the location of the holes easily.

    Hi masamasa, thanks for the information. I'll consider placing degassing holes on the route keepout layer as you mentioned.
