In this paper, we report a comparison of interfacial reactions of Sn-3.8Ag-0.7Cu (SAC 387) and SAC (0-1.5 Zn) solder pastes on Cu (organic solderability preservative finish) and Au/Ni-P/Cu [electroless Ni immersion gold (ENIG)] substrate metallizatio

Metalized micron scale polymer particles have been utilised in anisotropically conductive adhesives for a number of years and more recent work has investigated their selective deposition to provide interconnects. In this work such particles have succ

We deposit dense, ordered, thin films of Au–dodecanethiol core/shell nanoparticles by the Langmuir–Schafer (LS) printing method, and find that their resistance at ambient temperature responds selectively and sensitively to alkane odours. Response

The optical and electrical properties of dodecanethiol-stabilized nanoparticles (6 nm diameter gold core) have been investigated over a range of film thicknesses and temperatures. The surface plasmon resonance absorbance is found to be dependent on t

Flash pyrolysis–gas chromatography–mass spectrometry (Py–GC–MS) was applied to freeze dried cells of eleven bacterial species. Six species known to synthesise bacteriohopanepolyols (BHPs) were found to produce easily identifiable C27–C35 ho

The distributions of hopanoic acids, ranging from C 30 to C 34 , in the Messel oil shale were characterized in both the free and bound states. The bound acids were released by thermochemolysis in the presence of tetramethylammonium hydroxide (TMAH).

This paper describes the ultrasound assisted dispersal of a low wt./vol.% copper nanopowder mixture and determines the optimum conditions for de-agglomeration. A commercially available powder was added to propan-2-ol and dispersed using a magnetic st

Electroless copper plating of insulating substrates, such as printed circuit boards, typically requires the pre-deposition of a catalyst layer onto the surface to initiate the chemical reactions. Pd/Sn based catalysts are widely used, but carry a hig

The increasing demand for fine pitch flip-chip interconnection has led to significant interest in alternatives to the widely used solder joints. The use of mono-sized metal coated polymer based micro-spheres is emerging as a method to achieve more ro
