There is provided an electroconductive paste composition that can form a coating film having satisfactory thickness by single coating work. The electroconductive paste composition can form bumps having satisfactory height even by a smaller number of times of coating than that in the prior art technique. The electroconductive paste composition comprises a phenolic resin, a melamine resin, an electroconductive powder, a solvent, and a bump forming aid comprising a monohydric alcohol having a terminal methoxy group and having at least one ether bond. The electroconductive paste composition can be used in a printed wiring board.

摘要:
A printing unit includes a plurality of ink supply members for supplying inks different from each other to a printing area or printing area-like portion, and a plurality of detecting systems, each detecting an amount of the corresponding ink accumulated on the printing area or printing area-like portion. A control system controls the plurality of ink supply members to regulate an amount of ink supplied by each of the plurality of ink supply members so as to bring the amount of the corresponding ink accumulated into agreement with a predetermined value.
摘要:
The present invention is a method of manufacturing a light emitting display panel, which includes a laminated structure formed by laminating at least a flexible base layer, a first electrode layer, an EL layer, a second electrode layer and a flexible sealing layer in that order. The flexible base layer is provisionally attached to a rigid flat plate, and thereafter supplied to a main manufacturing step of the light emitting display panel. According to the feature, no significant unevenness in the thicknesses of layers formed on or above the flexible base layer is generated. Therefore, a light emitting display panel whose light emitting strength is uniform can be produced.
