Interfacial Adhesion Failure in Semiconductor Packages

Modified single cantilever adhesion test for EMC/PSR interface in thin semiconductor packages

Interfacial propulsion by directional adhesion

The rough integument of water-walking arthropods is well known to be responsible for their water-repellency [1, 2, 3, 4]; however, water-repellent surfaces generally experience reduced traction at an air-water interface [5, 6, 7, 8]. A conundrum then arises as to how such creatures generate significant propulsive forces while retaining their water-repellency. We here demonstrate through a serie...

Improving Interfacial Adhesion in Pla/wood Biocomposites

The Impact of Interfacial Adhesion on the Strain- To-failure of Montmorillonite/epoxy Nanocomposites

In polymer nanocomposites, many researchers suspect that the weak interface between the host matrix and nanoparticles is responsible for the often observed reduction in the strain-to-failure relative to the pristine host matrix [1]. In 2004, a new test methodology [2] was proposed for observing the onset of clay-matrix debonding in transparent clay based nanocomposites, with the debonding proce...

Molecular tailoring of interfacial failure.

Self-assembled monolayers (SAMs) provide an enabling platform for molecular tailoring of the chemical and physical properties of an interface. In this work, we systematically vary SAM end-group functionality and quantify the corresponding effect on interfacial failure between a transfer printed gold (Au) film and a fused silica substrate. SAMs with four different end groups are investigated: 11...
