Drill & Annular rings

 ProtiAnts

1. Drill diameter

  • All drill diameter from 0.4mm (0.2mm by series production) in steps of 0,1mm are available.
  • Plated-through holes are drilled approx. 0.1mm larger than the final diameter specified (the final diameter is achieved by the plating). 
  • If this increase is considered in the design, this should be specified in the order.
  • For component holes, annular rings have to be made larger. 
  • You have to output separete Drilling program for PTH and another one for Non-PTH.
  • Holes with a final diameter from 6.00mm are milled.

 

 

2. Annular rings

  1. Annular rings by plated holes:
  • To ensure a surrounding annular ring around the holes, the following parameters in the layout should be observed.

 

  1. Annular rings by non-plated holes:
