![]() This is valuable when the the design objects are very small, and is particularly valuable for drilled pads and vias, because mis-alignment between the drill center and the pad/via center can result in the drill hole removing much of the copper connecting the track to the pad/via. Teardrops are often added to a routed PCB design to create stronger track-to-pad, track-to-via and track-to-track connections. This allows each teardrop shape to be created from a single region object, which can have then straight or curved edges.Teardrops can also be added to the junction of 2 tracks, at both a T-junction and a neckdown junction. In Altium Designer 14.3, teardrops were changed, they are now created from Region objects instead of Track or Arc objects.
