WebThe die is subjected to a stress parallel to the substrate. This causes stress at the interface between the die and the die attach material. The force needed to break the bond is the die shear strength. A high die shear strength is >3400 psi (10 kg). Many of our semiconductor adhesives used in electronic assembly exhibit very high die shear ...
