METHOD OF SUCTION OF OBJECT TO BE WORKED UPON SUCTION UNIT AND METHOD OF MANUFACTURE OF CERAMIC CAPACITOR

WIPO Patent Application WO/2011/089926

A1

Disclosed is a method of suction of an object to be worked (15) upon a suction unit (14) and a method of manufacturing a ceramic capacitor, which employ a plastic sheet (11) being air permeable in the thickness dimension thereof as a suction sheet, having improved air permeability while maintaining a small diameter for the pores (aperture diameters) that are the air permeable paths for ensuring the air-permeability. The plastic sheet (11) is a non-porous sheet whereupon two or more through holes are formed that pass therethrough in the thickness direction. The through holes are straight holes that pass through the plastic sheet in direct lines. The diameter of the through hole is less than or equal to 20µm. The air-permeability of the plastic sheet in the thickness direction is less than or equal to 10seconds/100mL, a Gurley number measured in accordance with JIS P8117. Under the methods disclosed herein, the plastic sheet (11) is positioned upon the suction face of the suction unit (14).
