Wire Bond / Ball Shear Application Note

Ball bonding is the process in which pads are connected onto a die and leadframe (or substrate) using very fine diameter wire. The basic steps of ball bonding include the formation of: the first bond (normally on the chip), the wire loop, and the second bond (normally on the substrate). The wire-bonding cycle is shown in Figure 1. P.8 Figure 1.

Relatively speaking, this is the strongest strength feat in the entire Pilaf saga and possibly the Dragon Ball era that doesn't involve the Oozaru. It even sticks out among Dragon Ball as a whole, given the range. However, we must take into context that this is a squeezing force, which operates in different ways than lifting or striking strength.

Big Forearms, Crushing Grip - T NATION

Bodybuilders are often only concerned with forearm size, which requires an entirely different approach from grip strength. For a stronger grip, choose passive crushing, active crushing, pinch gripping, and thick bar work. For bigger forearms, choose wrist curling, static holds, and extensor work, all with moderate loads for higher reps.
