How to: shear
How to: Shear This manual advises what to consider and how to perform an optimal shear test. The guide touches topics on shear tool design, tool quality, tool alignment, and […]
Why test bonds?
Why test bonds? Electrical and thermal bonds are such an integral part of electronic and semiconductor construction that they may often be taken for granted. Modern electronic assembly methods employ […]
Lid torque
Lid torque The purpose of this test is to determine the shear strength of the seal of glass-frit-sealed microelectronic packages. This is a destructive test.
SMD component shear
SMD component shear While 100 μm is currently a commonly used line width for printed circuit boards in the near future, this is expected to become as low as 20 […]
Passivation layer shear
Passivation layer shear As gold ball bonding geometries reduce, so does the height of the ball bond. The thickness of the passivation layer, though, remains the same. This creates a […]
Cavity shear
Cavity shear Cavity Shear tools have a semi-cylindrical recess (cavity) that distributes the shear load on a ball over a much larger surface area. This reduces ball deformation and increases […]
Total ball shear/zone shear
Total ball shear/zone shear Total Ball Shear (TBS) or zone shear tests all or many rows of balls in one operation, producing more bond or pad failures. Using a wide-shear […]
Ribbon shear
Ribbon shear Ribbon shear test and wire pull tests are used to assess the quality of bonded aluminum or copper wire and ribbons. The ribbon shear test is comparable to […]
Copper tab/conductor shear
Wedge shear
Wedge shear Wedge shear test and wire pull tests are used to assess the quality of bonded aluminum or copper wire and ribbons. The wedge shear test is comparable to […]
