Multi-factory Compatible Drill Table

2/07/2013 0 Comments

This is the drill table built into CircuitHub issued templates and the "drill(..)" API command. Drawing your holes this way ensures compatibility with the broadest set of factories and, therefore, provides cost savings. You can callout any arbitrary size in a CircuitHub template, but you should limit yourself to this list, unless your needs can't be explicitly met by it. Anything bigger than the largest drill bit listed can be sized exactly as you desire, since most facilities will switch to routing instead of plunging above that diameter.
If you need a hole in this range Consider drawing it this size Tolerance With this diameter pad and this diameter inner clearance
