Improved slit nozzle for flat panel detector manufacturing

Flat panel detector manufacturing

A flat panel detector manufacturer was looking for an improved slit nozzle for its production process. Slit nozzles, also known as water knives or aqua knives, discharge purified water or chemical solutions in the form of a thin liquid film onto workpieces.

Benefits of TAIFUJet®

Chemical resistance

Uniform liquid film formation

Low flow rate

Excellent responsive rate

The outline of the project:

Chemical resistance: Must be made of materials that can withstand etching solutions.

Uniform liquid film formation: Stability is essential as it directly impacts product quality.

Low flow rate: Enables savings on expensive etching solutions.

Excellent responsiveness: Must allow rapid on/off control of liquid film discharge.

Drip prevention: No liquid should drip after spraying stops.

These requirements were highly demanding and exceeded the performance capabilities of existing nozzles by a significant margin.

The solution

The requirements presented by the customer were exceptionally challenging. However, Ikeuchi Japan committed to developing, designing, and manufacturing a slit nozzle that meets all the performance criteria, including chemical resistance, stable and uniform liquid film formation, low flow rate, high responsiveness with on/off control, and drip prevention.

To drive the project forward, a dedicated team was formed, comprising the customer’s development engineer, the sales representative, and the chief design manager from the Ikeuchi Japan factory. Starting from scratch, they conducted multiple rounds of design and prototyping, presenting spray demonstration videos of each prototype nozzle to the customer to systematically resolve their concerns.
As a result, Ikeuchi Japan successfully developed a slit nozzle that met all the requirements, and the delivery of mass-produced units has finally begun.

System used for this application

Optimized etching process

Reduced consumption of expensive solutions

Uniform liquid film thickness

TAIFUJet® air nozzles

Switch to our high impact energy-efficient TAIFUJet® air nozzles. They are also known for their lowered noise level.

The result

The design of a new flat panel manufacturing equipment model, featuring high-performance slit nozzles that apply etching solutions with precision and uniform liquid film thickness, has been successfully completed. These nozzles optimize the etching process and significantly reduce the consumption of expensive solutions, resulting in a more efficient piece of equipment.

This equipment is now being deployed in FPD production facilities across various Asian countries, playing a vital role at the forefront of precision flat panel manufacturing.
