Differences with conventional porous chucks

What is a porous chuck?

A suction jig that uses a porous material to hold and secure a workpiece.
The workpiece is held in place with suction, by applying negative pressure (vacuum) to the interconnected fine pores.

Material
Ceramic materials with countless fine pores are used. Has high heat resistance, chemical resistance, and mechanical strength.
Structure
Comprises a porous body and metal base that holds it in place.
How suction works
By applying negative pressure through the suction port, the entire surface of the porous material adheres uniformly to the workpiece.

MICRO Vacuum Chuck

What is a
MICRO Vacuum Chuck?

An ultra-high-precision vacuum suction jig developed by Micro Technology.

Instead of porous material, the workpiece (object) is held in place using a suction plate made with processing fine holes in a glass plate.

MICRO Vacuum Chucks feature excellent transparency and a high degree of freedom in design and layout.

Material
Both the suction plate and the body are made only of glass. In addition to high heat resistance and chemical resistance, they offer excellent transparency, insulation and flatness.
Structure
Comprises a glass suction plate with fine holes formed by precision processing and a glass body with fine grooves.
How suction works
By applying negative pressure to straight holes with a minimum diameter of 10 μm, the entire surface of the suction plate adheres uniformly to the workpiece.
Tasks that were difficult with ceramic porous chucks
are now possible with the MICRO Vacuum Chuck.

MICRO Vacuum Chuck

6 Advantages

1

Enables observation and work while under suction

Both the suction plate and body are made of transparent glass, so it is possible to observe (inspect) the workpiece while it is still attached.

Tasks that were difficult with porous chucks, such as shining light or UV light from below the body or photographing through the chuck with a camera, are now possible.

2

Custom designs possible, such as suction force and partial suction

With high-precision processing of fine holes, parts with any hole diameter, pitch, or size (minimum diameter: 10 μm; minimum pitch: 30 μm; maximum size: 500 mm square) can be designed and manufactured.
Designs can cater to a wide range of needs, such as adjusting suction force to suit the workpiece shape and material, or providing suction in only specific areas.
An example is vacuum-suctioning thin workpieces such as wafers without causing damage.

3

Suction plate shapes designed with a high degree of freedom

Chucks can be manufactured with the desired shape to suit any application, such as a perfect circle, ellipse or square.

End-face machining is also possible, such as thread chamfering, C chamfering and R chamfering.

4

Reduces static electricity on the suction-plate surface

Forming fine textures (matte processing) on the glass surface helps to prevent the generation of static electricity during work.
For matte processing, the optional density (color tone) and design to suit work requirements can be specified.

5

Custom-made designs to fully meet objectives and applications

The body thickness, size, and shape and depth of grooves can also be freely customized to suit any needs, similarly with the suction plate. This ensures a fully custom-made vacuum chuck to suit objectives.
6

Precision polishing of the suction plate is also available

Applying precision polishing of TTV ± ~ μm to the suction plate ensures even higher flatness and parallelism accuracy, as well as stable suction force.

Frequently Asked Questions

Frequently Asked Questions

What is the maximum size of the glass chuck and glass body?

Up to 500 mm square is available

What is the maximum thickness of the glass chuck and glass body?

Up to 1 mm for the glass chuck, and 10 mm for the glass body, for a combined maximum of 11 mm.

What is the production lead time?

The standard lead time is about 1.5 months after placing an order, but can be delivered quicker depending on the situation. Please let us know if you have any specific requests.

How many units can I purchase from?

Purchases start from a minimum of 1 unit.

Is it possible to borrow a sample?

We can lend samples. Please contact us via the inquiry form.

What is the approximate cost?

After confirming your desired specifications, we will prepare an estimated quotation. Please feel free to contact us using the inquiry form.

What is the difference with a porous chuck?

The principle behind holding and securing the workpiece is the same as that of a porous chuck.
The MICRO Vacuum Chuck offers the advantage of allowing suction zones to be created at any desired location, as the holes are formed with fine processing.
Given the high transparency of glass, tasks such as observation while the workpiece is under suction, are also possible.
