Singulating Products by Cutting Them with High Precision
and at High Speed
Our Commitment to Technologies
Singulation Technology
Singulation, one of core technologies in the post-process of semiconductor manufacturing, is a technology we are working on since the 1990s. We combine high-speed handling technology and image analysis technology with cutting technology that we have cultivated over many years, and we are offering high-quality singulation equipments.
- In-House development of all major functions such as dicers and handlers
- Improving productivity by working on enhancing cutting precision and increasing conveying speed
- Responding to the downsizing of products, the upsizing of substrates and other changes ahead of others
Developing all major functions in-house
In singulation process, the molded substrate is divided into individual pieces by a dicer in a molding machine. Separated products are transported by a handler and stored in a tray or the like.
The world's first singulation equipment was developed by the group company of TOWA. Since then, we have been offering a system dedicated to package singulation, by developing our own Dicer and Handler.
Correspondence to warpage of substrate
For dicers responsible for individualizing products, it is important to deal with shrinkage of resin during molding and temperature change during cutting.
Corresponding to the warp of the board, by dividing into pieces with high precision, the yield of products is greatly improved. We are constantly developing and improving our company so that we can develop Dicer by ourselves and provide optimal singulation method according to customer's type of products to be manufactured.
The handler which is another major constituent function contributes to the improvement of the customer's production capacity by high throughput by taking advantage of know-how accumulated over many years by our company.
Applicable to smaller products and larger substrates
In recent years, in addition to reducing production costs, there is a strong demand for compactness and thinning of products. For small products up to 1mm X 1mm, TOWA adopts an adsorption jig type using a vacuum pump rather than a tape type which isn't suitable to reduce the manufacturing cost.
In the future, as substrate size increases further, high precision is required for rotation control of Dicer's cut table. We will respond to such issues quickly and flexibly with our own Dicer.
The first-generation singulation system
Alignment (The optimal cutting position along the workpiece is determined.)
Dicer (The substrate on the cutting table is cut with the blade.)
Handler (For handling and storing products in the tray.)
