With the large variety of specification required in creating your Printed circuit boards, PCB Global’s Computer Aided manufacturing (CAM) Engineering department will invariably have a few Engineering Questions (EQ’s) to confirm. One example of a typical EQ relating to Stub Track is shown below:

Stub Track

EQ from CAM:

Stub track that leads to nowhere and has no hole as a through connection.


Small copper stubs that end with a dead end no connection are generally not a problem to fabricate, however, we need to ensure that no via or other connection has been omitted.


With confirmation from our customer this stub track was deleted resulting in a clean pad finish and the net was terminated at the via.
