    • It is possible to obtain a screen printing method that may assure excellent printing qualities since the screen printing method of the present invention includes: (A) sliding a squeegee head with paste stored in the squeegee head on a mask plate, while the past is pressurized, and printing the paste on a substrate through pattern holes of the mask plate, (B) at least one step of (b) separating the squeegee head with the paste stored therein from the mask plate, and (e) sliding the squeegee head on the mask plate for a pre-squeezing purpose before the step (A). The step of separating the squeegee head from the mask plate includes the steps of (1) discontinuing the pressure application to the paste stored in the squeegee head, (2) horizontally moving the squeegee head by a predetermined distance while the bottom end portion of the squeegee head is abutted on the mask plate in a state of the pressure application being discontinued, and (3) moving the squeegee head upward off from the mask plate. In the step of pre-squeezing includes the steps of (1) pressurizing the paste stored in the squeegee head in a state of the squeegee head being abutted on the mask plate, and (2) horizontally moving the squeegee head while the bottom end portion of the squeegee head is abutted on the mask plate in a state of the paste being pressurized.
    • 由于本发明的丝网印刷方法包括以下步骤,可以获得能够确保优异的印刷质量的丝网印刷方法:(A)将刮板头上存储的刮板头的刮板头滑入掩模板上,同时过去被加压 ,并且通过所述掩模板的图案孔将所述糊料印刷在基材上,(B)至少一个步骤(b)将所述刮板头与所述掩模板中存储的糊料分离,以及(e)将所述刮板头 在步骤(A)之前用于预挤压目的的掩模板。 将刮刀头与掩模板分离的步骤包括以下步骤:(1)停止对存储在刮板上的浆料的压力施加,(2)将刮板头水平移动预定距离,同时, 在施加压力的状态下,刮板头抵接在掩模板上,(3)将刮刀头从掩模板向上移动。 在挤压步骤中,包括以下步骤:(1)在刮板头的状态下,在刮板上抵接的状态下对存放在刮板上的浆料进行加压,(2)水平移动刮板头,同时底部 在糊状物被加压的状态下,刮板头抵接在掩模板上。

    • There is disclosed a solder paste screen printing apparatus and a solder paste screen printing method, in which a force of pressing of a squeegee can be adjusted delicately and accurately so as to effect the printing of solder paste with the optimum pressing force. A squeegee is connected to a lower end of a rod of a cylinder, and a load cell is provided above the rod. A first pressure and a second pressure are applied respectively to an upper chamber and a lower chamber of the cylinder. A load, applied to the load cell, is measured while varying the level of the first pressure, and the pressure measurement for the pressing force is effected in accordance with the measured load. In accordance with this result, the instruction pressure for the cylinder, which is necessary for obtaining the optimum pressing force, is determined, and then the printing of solder paste onto a substrate is started with this instruction pressure.
    • 公开了一种焊膏丝网印刷装置和焊膏丝网印刷方法,其中可以精细且精确地调节刮板的压力,以便以最佳的压力实现焊膏的印刷。 刮板连接到气缸的杆的下端,并且在杆上方设置有称重传感器。 第一压力和第二压力分别施加到气缸的上室和下室。 在改变第一压力的水平的同时测量施加到称重传感器的负载,并且根据测量的负载来实现按压力的压力测量。 根据该结果,确定获得最佳按压力所需的气缸的指示压力,然后以该指示压力开始将焊膏印刷到基板上。
