LED Package


An LED (Light Emitting Diode) is a semiconductor chip that emits light when an electric current is applied. It consists of a substrate made of GaP (gallium phosphide), GaAs (gallium arsenide), GaN (gallium nitride), sapphire and others, and a light-emitting layer. The LED is widely used for mobile phones and traffic lights.

*Recently, the blue LED development has allowed white light-emitting devices to be realized. In the future, demand is expected to emerge for LED lights for home use.

[LED package manufacturing process]

We have ring-type (resin bond, electroforming, metal bond) and hub-type (electroforming) dicing blades. Electroforming blades that can be made smaller and thinner are mainly used for the cutting process for LED packages.

[Case study]

The following is an example of our ring-type electroforming blades being used:

Processing requirements

Workpiece LED Package 0.5mmT
Blade Electroforming Blades
Mesh Size #1200, O.D. φ54mm, Blade thickness at 0.1mm, with a slit
Feed Rate 120mm/sec

Cutting plane

In the cutting process for LED packages, burr suppression for the electrode is important. The selection of blade specifications effective for burr suppression and a processing technique for taking advantage of the burr suppression effect are required to solve burr problems. The result is given in the photo on the right.
