Problems solved by technology

If the wire is wound up on a spool for used wire when the wire is still efficient and safe enough to saw other objects such as wafers, the wire is not used optimally, causing financial loss
On the other hand, if the wire is continued to be used even though it is no longer suitable for further sawing, the wire can break or cause unsatisfactory sawing results
Thus, again, such an option is economically unacceptable

Abstract

The invention discloses a wire saw control system and a wire saw. The wire saw control system (1) for operating a wire saw (100) is provided. The wire saw is adapted for cutting a wafer (304, 304, 306, 308) by moving the wire (230) relatively to the wafer with a selectable wire speed. The wire saw control system includes a camera (20) for inspecting the wire, and a camera control unit (25) for operating the camera in dependence of the wire speed. Furthermore, a wire saw including the wire saw control system is provided, and a method for inspecting a wire of a wire saw. The method includes moving the wire with a variable wire speed; and inspecting the wire in dependence of the wire speed, thereby obtaining an inspection result.

Description

technical field [0001] The invention relates in particular to a wire saw control system for checking the wire of a wire saw, a wire saw, a method for checking the wire of a wire saw and a method for operating a wire saw. Existing wire saws can be retrofitted with the wire saw control system according to the invention. More specifically, the present invention relates to a wire saw control system for detecting defects, wear or damage to a wire of a wire saw. The invention relates in particular to multi-wire saws. The wire saw of the invention is particularly suitable for cutting or sawing hard materials such as blocks of silicon or quartz, for example for cutting silicon wafers, for squarers, for sectioning machines and the like. Background technique [0002] Wire saws are used for cutting blocks or bricks, thin slices, eg semiconductor wafers, from a sheet of hard material such as silicon. In this device, wire is fed from a spool and is guided and tensioned by a wire guide...
