Failuresfrom die shear testing include: 1) failure to meet the specified die shear strength requirements; 2) a separation that occurs at less than 1.25X the minimum die shear strength and evidence of less than 50% adhesion of the die attach material; and 3)a separation that occurs at less ...
This study evaluates adhesion between the flip-chip underfill and the passivation utilizing a die shear methodology. The test vehicle utilized for this study is a 100-mil square peripherally bumped die provided by Flipchip Technologies. The die are identical with the exception of the three ...

Layer-by-layer shear Microstructure Mechanical properties 1. Introduction 6005A aluminum alloy is a type of medium-strength aluminum alloy belonging to Al–Mg–Si system of wrought alloys. It has high plasticity, good welding properties and corrosion resistance as well as excellent hot extrusion prop...
In sum, to perform package assembly, die bonding on the lead frame is one of the essential processes. The existing test method, referred to as a die-shear test, verifies the strength of the die-attach to the lead frame. It is a destructive test and measures the force that is needed to...
