    The study focused on exploring the impact of micro-textured surfaces on the wetting behaviour of Sn-0.7Cu solder. Dimple and pillar micro-textures, each with a diameter of 100 μm, were fabricated on the copper substrate using a photolithography technique. The Sn-0.7Cu solder was melted onto the micro-textured copper substrate during the soldering process. The spreading time, spreading area, and spreading rate of the solder on the copper substrate were investigated. The copper substrates with dimple textures exhibited a prolonged spreading time of 51 seconds, a smaller spreading area of 60.54 mm², and a slower spreading rate of 1.44 mm²/s than the pillar-textured copper substrates. However, the presence of micro-textures resulted in a reduced spreading area, indicative of enhanced solderability. This improvement is attributed to the textured substrate promoting higher copper diffusion during the soldering process. The controlled application of micro-textures holds promise for optimising wetting behaviour and solderability in electronic assembly processes, presenting avenues for further exploration and application in the realm of materials science and electronic manufacturing.

    Since the discovery of exceptional properties of graphene, a lot of researchers focused on the discovery of another nobel two-dimensional (2D) materials. Recently, an elegant exfoliation approaches was proposed as a method to synthesis a new family of transitional 2D metal carbide or nitrades of MXene from a layered MAX phase. A layered MAX phase of Ti3AlC2 was synthesized through pressureless sintering (PLS) the initial powder of 3TiH2/1.1Al/2C without preliminary dehydrogenation under argon atmosphere at 1350°C. An elegant exfoliation approach was used to eliminates Al from its precursor to form a layered-structure of Ti3C2. In this study, thermal conductivity of MAX phase and MXene were studied using absolute axial heat flow method to measure the abilities sample to conduct heat and the data was collected using Picolog 1216 Data Logger. Electrical conductivity of these two materials was also compared by using two-point probe, due to its simplicity. Radiation properties of 2D MXene Ti3C2 was studied by using an established radon monitor, placed in closed, fabricated container. Morphological and structural properties of this 2D material were also studied using an established FESEM and XRD apparatus. SEM images shows two types of morphology which is a layer of Ti3C2 and the agglomerates Al2O3 with graphite. XRD pattern reveals three phases in this material which is a rhombohedral Al2O3, rhombohedral graphite and rhombohedral Ti3C2 phases, respectively. Thermal and electrical conductivity of MXene were proven higher than MAX phase. Radon concentration for this material for five consecutive days explains the radiation level of this material which is under the suggestion value from US Environmental Protection Agency (EPA). From this finding, it is can conveniently say that the MXene material can be promising material for electronic application.
