Latest Patents

One of Miyayama's latest patents is for a photosensitive conductive paste. This innovative paste comprises a water- or alkali-soluble acidic-functional-group-containing organic binder, a photosensitive organic component, an organic solvent, and a conductive powder such as iron or copper. Additionally, it includes a mono-ol compound with a boiling point of about 178°C or higher, such as dipropylene glycol monoethyl ether, and/or a diol compound like pentamethylene glycol. This photosensitive conductive paste is noted for its excellent storage stability and consistent development.

Another significant patent involves a process for manufacturing a printed circuit board with plated landless through-holes. This process includes filling a radiation-curable putty material in through-holes plated with copper in a substrate. The material is then cured under radiation, followed by the application of a liquid resist on the substrate surface. The resist is exposed using a mask with a circuit pattern, developed, and the substrate surface is etched. The filling material composition used in this process consists of various components, including a hydrophthalic mono ester compound, a catalyst for promoting photo polymerization, a highly transparent rosin, and a powder of at least one extender.
