Problems solved by technology

[0005] However, although the above-mentioned closed-type squeegee coating mechanism generally has good filling performance, it may not always be possible to ensure the necessary filling performance when it is targeted at materials that are more difficult to print, such as when it is targeted at a mesh mask with a fine grid pattern. fully filling case

Embodiment Construction

[0038] Next, embodiments of the present invention will be described with reference to the drawings. First, refer to figure 1 The structure of the screen printing device 1 will be described. This screen printing device 1 has a function of printing a soldering or circuit on a substrate through a pattern hole by performing a squeegee operation in which the squeegee unit comes into contact with the upper surface of a mesh mask with a pattern hole and slides in the squeegee direction. The function of the paste used for forming.

[0039] exist figure 1 , figure 2 Among them, a screen printing unit 10 is disposed above the substrate positioning unit 2 of the screen printing device 1 . The substrate positioning unit 2 is configured such that a θ-axis table 5 is stacked on a movable table composed of a Y-axis table 3 and an X-axis table 4 , and a first Z-axis table is arranged on the θ-axis table 5 6A, the second Z-axis table 6B, and the substrate lower support portion 7 is dispo...

Abstract

In a squeezing operation by a closed type squeegee mechanism which is configured so that paste compressed internally is packed from a printing opening between a pair of sliding members, before the packing of the paste into pattern holes via the printing opening, the sliding member positioned on a leading side of a squeezing direction between the pair of sliding members and moves in the squeezing direction so that the paste supplied to the outside of the closed type squeegee mechanism on an upper surface of a mask is packed into the pattern holes.

Description

technical field [0001] The present invention relates to a screen printing device and a screen printing method for printing paste on a substrate for component joining or circuit formation. Background technique [0002] Screen printing is known as a method of supplying a paste for joining components, forming a circuit, or the like to a substrate. In this method, a screen printing device is used, which is equipped with a device for printing paste on the electrode surface of the substrate through pattern holes provided in the screen mask and bringing the substrate into contact with the lower surface of the screen mask. A screen printing mechanism that slides the squeegee coating unit on the screen mask in the state (for example, Patent Document 1). [0003] In the example shown in this patent document 1, as the squeegee unit, there is shown an example using a closed type squeegee mechanism configured as follows, that is, a paste box storing paste is installed inside, and the pa...
