Abstract Gold metallization of 3D printed polymer structures was conducted by a supercritical carbon dioxide (sc-CO 2 ) assisted electroless plating process. Precursor the Pd catalyst utilized in this study palladium bis-hexafluoroacetylacetonate for high solubility sc-CO . A Ni–P layer first formed on catalyzed structure as sacrificial sequential gold deposition. Electrical resistance metalliz...

Micron-sized gold plates were prepared by reducing chloroauric acid with lemongrass extract. Their two-photon luminescence (TPL) and second harmonic generation (SHG) were investigated. The results show that the TPL and SHG intensity of gold plates is dependent on the wavelength and polarization of excitation laser. The TPL intensity of gold plates decreases with the increase of the excitation w...

As the laminate substrate industry moves from Hot Air Solder Level (HASL) finishes, alternate plating finishes are being proposed such as immersion gold/electroless nickel, electroless palladium and electroless silver. This paper presents results of an evaluation of the thermosonic gold ball wire bondability of electroless palladium. Two palladium thicknesses, with and without a nickel underlay...

Abstract A goal of advanced packaging design performance is to reduce power and achieve better control heat electromagnetic interference. Materials efficient include the use gold (Au) wire, copper (Cu) alloy, gold/silver (Au/Ag) plating, solder, low-k epoxy dry-film polymers, silicones polyimides. Material purity verification contamination during production process a prerequisite ensure high yi...

Activated carbons are extremely versatile adsorbents for major industrial significance, especially for metal ions recovery from wastewaters. In this study, the activated carbon prepared from the hard shell of apricot stones, an agricultural solid, which was used for the gold recovery from gold-plating wastewater is investigated. Activated carbon was produced by chemical activation with phosphor...

As shown in article number 2002133 by Rong-Ming Ho and co-workers, gold nanohelices for chiral plasmonic polymer films can be fabricated using self-assembled block copolymers as templates templated electroless plating. The nanohelix serve absorber scatterer the polymeric manipulating circular-polarized light based on its chirality. This bottom-up approach suggests a facile method fabrication of...
