The surface energy of solid surfaces and surface tension of liquids are important parameters in the IC package assembly process. Wettability analyses have been completed for various materials used in the assembly process of flip chip packages, including underfills, substrates, fluxes, and lead free solders. We will highlight some of these results in this paper. We will focus our discussion on substrate surface energy analysis. A brief discussion of different surface energy methods and the liquid selection criteria will be given. The advantage and limitation of the surface energy calculation methods will be discussed. The data from several case studies will be presented. Our results show that contact angle and surface energy measurements are very useful for quality control and product development where interfacial properties are important.

We report the photocontrollable micelle–cluster transition of an ABC-type triblock copolymer in an ionic liquid (IL). Polystyrene-b-poly(ethylene oxide)-b-poly(4-phenylazobenzyl acrylamide-r-N-isopropylacrylamide) (PSt-b-PEO-b-P(AzoBnAm-r-NIPAm)) was synthesised, where PSt is IL-phobic, PEO is IL-philic, and P(AzoBnAm-r-NIPAm) is photo- and thermoresponsive in the IL. At high temperatures, the triblock copolymer forms micelles with PSt cores; furthermore, at low temperatures, micelles self-assemble into clusters induced by the aggregation of P(AzoBnAm-r-NIPAm). Under UV irradiation, the micelles form clusters at lower temperatures than that in the dark because of the change in the solubility of P(AzoBnAm-r-NIPAm) induced by photoisomerisation of the azobenzene groups, indicating that this triblock copolymer has a photocontrollable micelle–cluster transition temperature.
