摘要:
According to an embodiment of the present invention, a method of producing an electronic circuit comprises printing first metal-containing resin particles which consist of at least a thermosetting resin and fine metal particles and second metal-containing resin particles which consist of at least a thermoplastic resin and fine metal particles by electrophotography to form a first base pattern which consists of the first metal-containing resin particles and a second base pattern which consists of the second metal-containing resin particles on a substrate; forming a first metal conductor layer on the first and second base patterns; forming a second metal conductor layer on the first metal conductor layer by electrolytic plating by supplying electric current to the first metal conductor layer; and removing the second base pattern and the first and second metal conductor layers which are formed on the second base pattern.

A conductive underlayer is formed in an electrophotographic manner using a toner comprising toner particles containing a binder resin containing a green thermosetting resin and conductive particles having an average particle diameter of 0.05 μm to 1 μm, wherein 50% by volume particle diameter of the toner is in a range 4 μm to 12 μm and the ratio of the toner with a size of 4 μm or smaller is 20% by number or less, or a toner including external additives containing hydrophobic-treated small size metal oxide particles having a BET specific surface area of 150 m2/g to 400 m2/g and large size metal oxide particles having a BET specific surface area of 10 m2/g to 70 m2/g and then a conductive layer is formed thereon by plating.
摘要:
By using an application unit having: a storage chamber for a viscous material; a discharge hole, for the viscous material, provided so as to communicate with the storage chamber, where a viscous-material feeding device for feeding the viscous material to the storage chamber is coupled to the application unit; and a discharge-pressure adjusting device for imparting a discharge pressure to the viscous material stored in the storage chamber, a screen mask having openings corresponding to the application object or the application object itself and the discharge hole of the application unit are brought into contact with each other, either the application unit and the screen mask or the application unit and the application object are moved relative to each other while the discharge pressure is imparted to the viscous material in the storage chamber, and the viscous material is applied onto the application object while the storage chamber is replenished at all times with the viscous material by the viscous-material feeding device with a pressure smaller than the discharge pressure imparted by the discharge-pressure adjusting device.
摘要:
A wax dispersion in a developing agent using a polyester resin is improved by adding an ester wax in the polyester polymerizing step or both in the polymerizing and kneading steps, or by adding a compatibilizing agent selected from the group consisting of alkylene block copolymer or graft copolymer to a polyester-styrene hybrid resin used in place of the polyester resin.
摘要:
A main wiping portion which contacts the back of a mask through a cleaning paper is provided behind a suction port as viewed in the direction of movement of an air suction portion. The cleaning paper is able to wipe off both solder paste adhered on the back of the mask and solder paste discharged from openings of the mask by suction through the suction port, whereby the solder paste deposits on the mask can be cleaned off at high removal efficiency.
摘要:
A component carrier assembly includes component holders each for holding a component therein and connected to one another in a form of a tape carrier. Each holder is provided with a cavity to accommodate the component, a closure for shutting an opening of the cavity, and a device for securing the lid structure in a closed position. An apparatus for feeding the component carrier includes a device for transferring the component carrier, a device for forcibly opening a closure of a component holder transferred to a predetermined position, and a device for forcibly closing the closure of the component holder after a component is removed from the cavity.
