FAQ

What are the available holes sizes?

14 mils to 150 mils - 1 mil increments

150 mils to 200 mils - 5 mil increments

above 200 mils - holes would be routed out

We only use drills in imperial units. Files submitted in metric units (mm)  would be converted to imperial units (mils) and rounded up to the next mil.

I am used to designing in metric units while the website is specified in imperial units. Is there a conversion chart I can refer to ?

When requesting an online quote, the quote form can handle mm units as well as inches for dimensions.

How do I specify internal cutouts/milling in my design?

All internal cutouts/slots/milling should be specified on the same layer is the board outline. The the minimum routable slot size is 32 mils. During order time, please state this requirement in the "Special Request" section so that our CAM engineers is aware of it. This is not something we encounter often - so there are chances we may overlook it. Make sure it's known to us.
