Provided herein is a conductive pattern making method and conductive pattern, the method including forming a groove such that its width in an inlet area is bigger than its width in an inner area; filling the groove with a conductive ink composition; and drying the conductive ink composition so that a solvent contained in the conductive ink composition inside the groove is volatilized to reduce the volume of the conductive ink composition.

Method for making conductive pattern and conductive pattern

Provided herein is a method for manufacturing a conductive transparent substrate, the method including forming a plurality of main electrodes on the substrate such that the main electrodes are distanced from one another; and forming a connecting electrode that electrically connects two or more main electrodes such that the plurality of main electrodes are grouped into a plurality of group electrodes that are electrically disconnected from one another, thereby producing a conductive transparent substrate with excellent transmittance in a process of high yield.

Conductive transparent substrate manufacturing method, and conductive transparent substrate

Disclosed is a method for manufacturing a double-sided printed circuit board (PCB) having a circuit pattern by printing a conductive paste. According to the method of the present invention, a circuit pattern that is precise and highly conductive can be formed, and a reduction in raw materials and the simplification of processes are made possible. Also, due to the printing of the conductive paste, short-circuit can be prevented even when a conductive layer is bent or exposed to heat or physical impact.

Method for manufacturing a double-sided printed circuit board

Provided is a method for manufacturing an electromagnetic interference (EMI) shielding film, including: (a) providing a single insulating layer on a first protective film, the insulating layer being made of an insulating layer composition including at least one resin selected from a thermoplastic resin and a thermosetting resin and at least one filler selected from a flame-retardant filler and an abrasion-resistant filler; (b) providing a metal layer on the insulating layer; (c) providing a conductive adhesive layer on the metal layer, the conductive adhesive layer being made from a conductive adhesive layer composition including at least one resin selected from a thermoplastic resin and a thermosetting resin and a conductive filler; and (d) providing a second protective film on the conductive adhesive layer, and an EMI shielding film manufactured by the method.

Method for manufacturing electromagnetic interference shielding film

The present invention relates to an ink-cartridge for printers comprising a body formed having a filling hole on an upper surface thereof; a plurality of filling chambers inside of the body divided by a partition having a connecting hole; a discharging chamber connected to the filling chamber; an air chamber connected to the filling chamber via an air transferring channel so as to supply air to the filling chamber; an air suction valve installed in the air chamber; an air inducing channel inducing external air to the air suction valve; a blocking film attached to one surface of the body; and a cover installed in the other side surface of the body; and a pressure regulating part formed in a surface of an outer wall of the body and communicating with the filling chamber.

Ink-cartridge for printers

The present invention relates to a variety of conductive ink compositions comprising a metal complex compound having a special structure and an additive and a method for preparing the same, more particularly to conductive ink compositions comprising a metal complex compound obtained by reacting a metal or metal compound with an ammonium carbamate- or ammonium carbonate-based compound and an additive and a method for preparing the same.
