Hesse & Knipps (Deep Access) and Palomar wedge bonders require a slightly different shank style (Main body) than other wedge bonder Manufacturers. Two shanks are available, the “double flat” and also the “S-1” option. The “double flat” has 2 flats compared to the normal wedge single flat. The “S-1” option has one flat, plus a channel on the back of the wedge to feed the wire. Below is a representation of the two different styles, or you can download our datasheets listed below for review.
