Tests Performed in Drill Checks

Several drill checks analysis tests can be run. For each test performed, results might be reported to the result categories available for that test. In the result category descriptions in this document, the test name is indicated in parentheses after the category name.

Hole Size — Provides a list of all PTHs, NPTHs, and vias, as well as NPTHs that need pilot drills.

Hole Separation — Reports duplicate holes, touching holes and close holes.

Missing Holes — Reports missing drills for non-SMD pads.

Thermal Connection — Reports the absence of thermals for through-hole pin drills and calculates the total copper area of thermal connections through all negative power and grand and mixed layers.

PCB Aspect Ratio — Reports the relationship between board thickness and drilled hole diameters for the smallest through hole and vias (standard, blind and buried) in the tested drill layer.
