Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material used in a printer printing technique for manufacturing an electronic device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a material used in a printer printing technique for manufacturing an electronic device, and more particularly, to a printer capable of manufacturing an electronic device more quickly and efficiently, To materials used in printing techniques.

In order to produce a prototype having a three-dimensional solid shape, a method of making a cooperative work by hand and a method of producing by CNC milling are known depending on drawings. However, since the method of making the woodwork is by hand, elaborate numerical control is difficult and time consuming, and the CNC milling method is capable of precise numerical control, but many shapes are difficult to process due to tool interference.

Therefore, in recent years, product designers and designers have created a so-called three-dimensional printing method in which three-dimensional modeling data is generated using CAD or CAM, and prototypes of three-dimensional shapes are produced using the generated data.

A 3D printer (Three-Dimension Printer) is a printer that can create three-dimensional objects. The basic principle of 3D printing is to build a 3D object by stacking thin 2D layers.

3D printers have recently been used in a variety of industrial fields including high-tech industries, and the interest in related technologies is greatly increasing. 3D printers are being used to develop products in various fields such as toys, fashion and entertainment industries, automobiles with high technical difficulties, aerospace, defense, and medical equipment. The 3D printer market is small compared to general printers, but 3D printer demand is expected to expand sharply as low-priced models of less than US $ 1,000 are launched for consumers.

The principle of a 3D printer can be divided into a cutting type in which large chunks are cut into pieces, and a laminated type in which the layers are piled up. Most of the 3D printers used today are stacked prints using the principle of additive processing. While there is a loss of material because the cutting mold is to cut away the excess, the stacked type is a great advantage that there is no loss of extra material.

The 3D printer of the layered type typically uses the FDM method (or the FFF method) and the SLA method. In this regard, FIGS. 1A and 1B schematically illustrate a commonly used 3D printer approach.

Referring to FIG. 1A, in the FDM (Fused Deposition Modeling) method, a filament type material is extruded through a nozzle, and an extruded material is laminated on a bed to produce a desired object. Since the structure and program of the FDM system are simpler than those of other systems, the cost and maintenance cost of the apparatus are low, and it is applicable to various materials and has an advantage of being simple in structure and easy to be enlarged. On the other hand, there are some limitations in implementing difficult and smooth shapes, and the disadvantage is that the production speed is very slow.

Referring to FIG. 1B, the SLA (stereolithography) method is a method of laminating a resin accommodated in a water tank by a method of projecting and curing a laser. The SLA method has a high output accuracy and can produce a product with a higher resolution than the FDM method. On the other hand, since the liquid resin is used, a cleaning process is required after the fabrication, and a process of removing the supporting rods manufactured in the manufacturing process is additionally required.

On the other hand, such a 3D printer has been widely used in various fields, but in reality, it has not been utilized in production of electronic devices. Electronic devices are often produced in large quantities, but it has been difficult to efficiently manufacture them using 3D printers.

Accordingly, there is a demand for development of a device using a printer printing technique that is designed with a structure optimized for manufacturing electronic devices.

The manufactured electronic element and the terminal are electrically connected.

The material 12 of the electronic element to be injected into the first injection port 42 is stacked on the upper surface of the printing bed 30 to form an electronic element and the material 22 of the terminal to be injected into the second injection port is stacked on the printing bed 30, And the terminals are formed while being laminated on the upper surface.
