What is the difference between a slicer and a dicing saw?

A slicer, just like the root word "slice," is a cut in only one direction. It is a piece of equipment made to cut relatively thick materials or create grooves. Therefore, the equipment itself is a "large, high-rigidity, high-precision" piece of equipment.
A dicing saw, is a machine that cuts thin semiconductor wafers into dices, and is called a "dicing saw" because it gives the cut wafer a square shape, like that of dice rolled in a game of chance. Equipment that could offer both the features and functions of a dicing saw (fast cuts and ease of use) with a high-rigidity slicer was needed to mass produce electronic parts, and the slicing/dicing machine was born.

What workpiece sizes can you cut?

While it depends on the machine, we have a work table available that cuts up to a maximum 400 mm (model DLS3240). The multi-gang blades allow mass and bulk cutting as well. In addition, the maximum thickness of material that can be cut is 50 mmt. For more information, please contact us.

What is frozen cutting?

Generally, tape or wax (adhesive) is used to secure a product to be cut. YAC DAStech has found a third fixation technique, frozen cutting, in which tape or wax is not used to cut.
"Frozen fixation" makes it possible to fix materials for which adhesives could not be used and difficult materials (workpieces). The time and effort involved in attaching tape before and after the cut process and wax fixation is eliminated and cutting efficiency increased significantly.

What kind of workpiece can be used with frozen cutting?

You can use the technique for any material, whether thick or thin. Even if tape fixation and adhesive fixation are difficult, there is another way! Leave uneven, thin and deformed workpieces up to us. Chuck liquid (a special adhesive fluid that is transparent, colorless and odorless) is a fluid that fills gaps to securely fix workpieces.
We can fix not only glass, ceramic, and metals, but also semiconductor packages!

What is chuck liquid?

It's a fixative for frozen cutting and was developed by YAC DAStech.
A free-flowing liquid at room temperature, chuck liquid freezes at -15℃ while securely fixing a workpiece. The free flow of the agent makes gluing tasks simple, too! Drop chuck liquid onto the workpiece and cool to complete gluing tasks in a jiffy! The clamping force delivered at -15°C surpasses that of water or third-party fixatives.

What are the effects of using a chuck liquid?

Gluing is MUCH easier! Just swipe chuck liquid onto a substrate! Once you apply it to a workpiece and cool on top of the cooling table, it does not come unstuck! Simply pour warm water over the workpiece to detach. The chuck liquid quickly melts and the workpiece comes unstuck! Say goodbye to the days of sweltering hot glue and detachment work!
Chuck liquid consists only of highly safe ingredients and causes no problems in nonindustrial wastewater. Easily melts in warm water and washes away, requiring no difficult cleaning!

What are the running costs of using a frozen cutting specification? Is chuck liquid expensive?

We made a list of the costs of a company that formerly used wax.
The data compares the cost per unit for 1 month.

  Wax fixation   Frozen fixation
Equipment Wax   11,733 yen Chuck liquid   35,200 yen
Cleaning solution 420,000 yen 43,000 yen
Cleaning solution processing 0 yen 0 yen
Jig cleaning solution 15,200 yen 0 yen
Grinding fluid 1,000 yen 40,000 yen
Electricity 4910 yen 9,542 yen
Total 452,843 yen 127,742 yen
Man hours 1,400,000 yen 1,000,000 yen

Customers can rest assured that the power consumed by the chuck liquid and refrigeration equipment is also not very expensive.
The company significantly reduced its cleaning solution costs. Adhesion and detachment are simpler, which also reduces man hours. The cost comparison excluding man hours shows frozen cutting costs are a cheaper production method by approximately 330 thousand yen. Man hours were reduced from 2.8 to 2.0, which reduces the cost of labor by 0.8 man hours.

Is frozen cutting useful for all types of materials?

No. There are still several cutting themes that need to be solved.
Chuck liquid melts from the cut portion, so there is a limit to fixation to workpieces with small edges. It also depends on the material and shape of the workpiece.
In addition, there is a limit to how much burrs can be reduced in metal cutting. If machined for a long time, chuck liquid will weaken and may cause detachment of a workpiece. However, processing conditions can be reviewed and countermeasures can be implemented to prevent this from occurring. In either case, we will make proposals based on both the target material and cutting conditions.
