The invention is a method which deliberately applies exaggerated features (22,32) on the photo-image used to pattern the lead frame for etching. The resulting etched leads (20,25,29) will have a flat to concave shape at the end of the lead tips (23,26,30), which can be used to "self-center" wire bond paths, eliminating the slung wire tendency altogether, provided the wire path crosses the lead tip within the concave shape region. |
