Embodiment Construction

[0040] figure 1 The arrangement of each device of the solder paste printing system of the present invention is shown.

[0041] As a representative example of the printing system of the present invention, in addition to the screen printing unit 200, its configuration also includes an inspection unit 300 for inspecting the results printed on the screen printing unit (hereinafter referred to as printing unit) 200, and depending on the situation, In case the inspection unit 300 detects a poorly printed but repairable printing state, a plurality of dispenser units 400 are used to repair it.

[0042] Conventionally, in the case of applying solder paste, the solder paste to be applied is supplied to the mask surface in the printing unit 200, and after the preparation is completed, after the position of the mark is pointed and recognized, automatic operation is started, and printing After soldering the paste, the substrate is transferred to the downstream device. In this regard, as ...

Abstract

The invention provides a silk screen printing device and printing system. In the solder printing system equipped with the silk screen printing device, the invention increases the printing precision of the silk screen printing device while needing to repair the badness not repaired in the system even having printing badness in the silk screen printing device so as to improve the production efficiency of the product. Such that the printing device used in the printing of the silk screen printing device is made in the structure of using the metallic printing device having two stage elasticity and in the structure of the checking unit for checking the printing state after printing and the distributor unit of repairing the badness of the printing substrate according to the checking result, and using the system reflected in the next substrate by using the result sent to the silk screen printing device.

Description

[0001] The present invention is a divisional application of the patent application No. 200610141425.X filed on September 29, 2006, entitled "Screen printing device and printing system equipped with the device". technical field [0002] The present invention relates to a screen printing device, and more particularly to a printing device for printing solder paste and a printing system using the same. Background technique [0003] As a conventional screen printing machine, there is a device disclosed in JP-A-5-200975. The screen printing machine has: a stage portion with a substrate carrying in conveyor, a substrate carrying out conveyor, and a lifting mechanism; a mask having a transfer pattern as an opening; a squeegee, a squeegee lifting mechanism, and a horizontal direction. Applicator heads for moving mechanisms; controls for controlling these mechanisms. After placing the substrate loaded into the device on the stage, raise the stage part to bring the substrate close to ...
