AG(Array Grain) wheel.
The outstanding sharpness prevents clogging and burn mark, and the service life is more than twice as long as that of conventional Electroplated. It can be used for profile type and is effective in a wide range of machining operations from roughing to finishing.

Cutters with a metal base are available in "multi-cutters" and "single-blade types. Multi-cutters can cut and groove by combining multiple cutters with specifications suitable for the work material. Our unique technologies such as cutting edge shape, pitch accuracy, and accumulation accuracy realize high machining quality. The single-blade type is a cutter with a diamond or CBN abrasive grain layer formed on the periphery of the steel steel core. Electroplated, metal, or resin can be selected for the bond, and the cutting edge shape (V-shape, R-shape) and steel core shape (all relief, under-neck relief) can also be selected according to requirements.

There are two types of dicing blades: “hub type” and “ring type.” The hub type is primarily used for dicing semiconductor silicon and compound wafers. It consists of an aluminum base and a nickel-bonded diamond layer integrated into a single unit, making it easy to handle. The ring type is,Various PKGsIt can be used for a wide range of cutting and grooving applications, including electronic component materials. You can choose from three types of bonds: electroformed, metal, and resin. The electroformed bond allows for the production of ultra-thin blades as thin as 15 μm.Resin-bonded blades are widely used for cutting glass, ceramics, and various packaged components (such as QFNs) where chipping and cutting resistance must be minimized. For metal-bonded blades, you can select the bond best suited for each workpiece from a wide range of options—from high-rigidity types comparable to electroformed blades to types that offer superior cutting performance.

AA Diamond Technology Co., Ltd. manufactures hub-type dicing blades and provides high-quality products that meet a wide range of cutting needs.

EcoMEP diamond wire is a thin elongated wire with diamond abrasives electroplated onto high tensile wire using special technology. Compared to the conventional loose-abrasive method, the slicing (processing) time of rigid and fragile materials such as silicon and sapphire can be shortened. It is also possible to reduce cutting margins and processing strains, so improvement of yield can be expected. Because water-soluble coolant can be used, dust can be collected and recycled, making this an eco-friendly product that also reduces overall costs. Clients can try out our cutting machines at our testing laboratory, which enables us to offer machines and cutting conditions that are best-suited to the materials our clients need to cut.
