Summary: This article presents a straightforward and low-cost method that combines stereolithography (SLA) and selective electroless metallization (EM) for the fabrication of 3D parts with complex shapes and end-use multifunctionalities. A novel photocurable composite based on acrylate resin loaded with nickel (Ni) particles is developed for high-resolution SLA printing with self-catalytic properties. The metallized SLA cured samples exhibit good electrical and magnetic properties and improved robustness compared to their non-loaded counterparts. Selective metallization of 3D printed parts is achieved through multi-material SLA printing with strong adhesion at the interface, providing a cost-effective approach for rapid prototyping of functional free-form features on 3D structures.

Summary: This study investigates the effect of Au layer thickness on the surface morphology, Ni distribution and wettability of Sn-3.0Ag-0.5Cu solder on heated Cu pads with ENIG finish. It is found that Ni diffuses from the Ni layer to the Au surface, reacting with the ambience to form Ni oxides, which inhibit the interfacial reaction and result in barren zones. The size of the barren zones decreases with increasing Au layer thickness.

Summary: This study used bipolar membrane electrodialysis (BMED) to effectively remove and recover Ni2+, NH4+, total phosphorus (TP), and NO3- from electroless nickel-plating (ENP) wastewater. The results showed that current density significantly influenced ion removal and recovery efficiency, energy consumption, and ion migration velocity. BMED system equipped with more wastewater compartments improved the recovery efficiency and reduced specific energy consumption. The recovered products were of satisfactory purity and similar physicochemical properties compared to commercial counterparts.

Summary: This study presents the selective separation of nickel and gold ions from real rinse wastewater using the HFSLM technique, with organophosphorus extractant mixtures showing a synergistic effect on target Ni2+ ions but an antagonistic effect on non-target [Au(CN)(2)](-) ions. HCl was found to be the most suitable stripping agent, with high extraction and stripping percentages achieved for Ni2+ ions compared to non-target [Au(CN)(2)](-) ions.

Summary: The thermo-compression bonding properties of Cu/SnAg pillar bumps on electroless palladium immersion gold (EPIG) were evaluated in this study. It was found that the surface roughness of the EPIG was higher compared to the ENEPIG surface finish, resulting in higher filler trapping. Additionally, the contact resistance increased with the thermal cycle time, with a higher increase observed in the EPIG sample compared to the ENEPIG sample.

Summary: The use of polymerized high internal phase emulsions (polyHIPEs) as templates for electroless nickel plating enables the production of ultra-porous metallic lattice structures with consistent wall thickness. These structures have desirable properties and can be used in various applications. This study optimized the electroless nickel plating process on polyHIPEs and examined different atmospheres during the heating process to remove the polyHIPE template. The findings showed that distinct compounds were formed under different atmospheres, and the porous structure of polyHIPEs was retained in certain conditions.
