Wire Pull Hook

WPH-01 WPH-02 WPH-03


Wire Pull testing is an established methodology for testing the mechanical reliability of wire bonding interconnects used for Semiconductors. Load is usually applied at 90° perpendicular to the Device Under Test (DUT).

There are namely 2 methods of testing, Destructive and Non Destructive Testing. Destructive Testing tests the ultimate strength of the wire bond, until the point where the bond fails. Non Destructive Testing (NDT) applies a preload to the bonded interconnect for a certain duration. NDT is usually used for integrity and reliability test for high value devices.
