Abstract: A method and apparatus for separating glass panels that minimizes process failures and improves separation process consistency by utilizing a separation handle which applies the minimal pressure necessary to remove the edge portion from the glass panel. The glass panel is cut along the score line, which outlines the edge portions of the glass panel to be removed. The panel is placed upon the separating apparatus, which pumps nitrogen along the underside of the glass panel, causing the glass panel to float above the apparatus. Locating pins are inserted to position the panel on the stage. Once the glass panel is in place, a vacuum sucks the panel against the stage, holding the panel tightly against the stage. The separation handle is then inserted over the edge portion to be removed. A measured force is applied to the handle, with the force incrementally increased until the slow, controllable separation of the edge is achieved. This level of force is maintained until separation is complete.

Abstract: A method is provided for cutting a glass duct, whereby the glass duct can be cut off completely straight. In this method, the coating layer is first cut through all round at the axial location of the fiber where the fiber is to be notched before the notching and subsequent breaking off of the glass duct. To enable the use of this method for glass ducts of varying diameters, the glass duct can be retained in a fixed position during cutting, while a cutting member, as well as a counterpressure surface for the cutting member, are moved all round the glass duct. Because glass ducts of a relatively small diameter are pressed further sidewards by the cutting member than glass ducts of greater diameter, this method effectively limits this sidewards displacement to prevent the glass ducts from breaking in an unintended manner.

In this position, several parallel second cuts (4-9) are then made that are perpendicular to the first cuts, whereby, on each partial plate, an initial crack is induced on the leading edge.

Abstract: A method of producing a semiconductor device of the present invention is applicable to a multilayer wafer for leadless chip carrier packages and breaks it on a package basis. The method begins with a step of forming a generally V-shaped groove in one major surfaces of the wafer in the direction of thickness of the wafer. A weak, cleaving portion is formed in the other major surface of the wafer in alignment with the groove. A cleaving force is exerted on the wafer to thereby form a break in the cleaving portion, so that the wafer is caused to break from the groove toward the cleaving portion in the direction of thickness of the wafer. The cleaving portion may be replaced with a strong, non-cleaving portion, in which case the break is formed in the interface between the non-cleaving portion and the wafer due to a difference in cleaving force.
