Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pad printing, and more particularly, to an electrode printing apparatus using a roll-type pad for efficiently printing external electrodes having different polarities to small electronic components such as a ceramic capacitor and an electrode printing method using the same will be.
In general, printing is classified into a general printing method of printing a logo of a manufacturer on the surface of various products, a general printing method of printing various patterns and images to give a sense of beauty, and a printing method of giving a special function through printing.
The general printing method is roughly divided into a silk screen printing method and a pad printing method. In the silk screen printing method, a mask is arranged on the upper side of a printing object for printing, a printing ink is printed As a technique for printing on the surface of an object, the printing object of the silk screen technique is suitable for printing on various materials such as glass, cloth, metal and plastic in addition to paper.
The pad printing technique is a printing technique for transferring a print pattern through a pad to perform printing on a printing object. The printing technique is a printing technique in which a pad is brought into contact with a surface of a printing plate on which a printing pattern is formed, And then transferred to contact with the printing object at the upper portion.
Typically, a pad printing apparatus applies ink to a depressed pattern of a metal plate engraved with a printed pattern, transfers the depressed pattern applied with the ink onto a pad made of silicone rubber, and transfers the transferred pad to the printed object, I am printing.
That is, a pattern portion is formed so as to be recessed at a predetermined depth from the surface of a flat metal plate to form an intaglio pattern, and printing ink is applied over the entire surface using a predetermined ink application cylinder, The surface of the metal plate is wiped off so that the ink remains only in the recessed portion and the ink remains in the other portion, and then a pad made of an elastic material such as silicone rubber is pressed on the surface of the metal plate to remove ink remaining in the recessed portion in a predetermined pattern The ink is transferred to the pad, and then the ink-transferred pad is pressed against the object to transfer the ink pattern transferred to the pad to the object, thereby printing the object.
On the other hand, a typical example of a printing method for giving a special function through printing is a printing method for forming an electrode on an electronic component.
As a method of printing an electrode on an electronic component, a screen printing method, a gravure printing method, and a dipping printing method have been proposed.
In the screen printing method, since printing is discontinuously performed while the printing sheet is stopped, it is suitable for low-speed printing. In the process of printing the internal electrode pattern, the screen can not be kept constant and thus the screen is deformed, .
The gravure printing method is a method of intaglio printing in which a conductive paste is filled in a concave pattern portion formed on a surface of a roll and an ink in a concave pattern portion is transferred to an object under pressure with an unnecessary paste removed on the roll surface, Compared with the conventional screen printing method, the roll conveying speed is several tens of times faster, which is advantageous in productivity.
However, when the electrode for electronic parts is printed by the conventional gravure printing method, the uniformity of the entire printed surface is unclear, the microscopic uniformity within each pattern frequently occurs, and a precise mechanism control is required.
The conventional dipping method has a problem that the film portion formed on the electronic component has a convex shape due to the viscosity of the material and does not have a uniform printing surface, thereby deteriorating electrical characteristics and reliability.
In addition, the above-described printing methods are not suitable for small-sized electronic parts such as ceramic capacitors, whose length and breadth are mm units.
