Product Description:

• Wafer hoop ring is used in the wafer COB packaging process. The first step is to expand the wafer. The whole wafer film provided by the manufacturer is evenly expanded by using an expander, so that the wafer particles closely arranged on the surface of the film can be opened, which is convenient for the subsequent procedures.
• It is used for semiconductor and light-emitting diode wafer expansion fixed ring, which is composed of two strong rings inside and outside, so that the wafer and wafer are fixed and well expanded, so that the closely arranged wafer or grain attached to the surface of the film is pulled apart, and it is easy to pick up the wafer particles.

Features:

Applications:

• Semiconductor Manufacturing

Wafer growth: During the growth and expansion process of wafers, stable support is provided to ensure the shape and quality of the wafers.
Heat treatment: In high-temperature annealing and other heat treatment processes, it helps to evenly distribute heat and prevent wafer deformation.

• R&D laboratory

Experimental support: During the research and development phase, provide support for different materials and processes to facilitate experimentation and testing.

• Transportation and Storage

Protective device: As a protective tool during the transportation and storage of wafers, it reduces the risk of physical damage.

Usage:

• Cleaning: Before use, ensure that the surface of the expansion ring is clean, removing dust, oil stains, and other contaminants to avoid affecting the quality of the wafer.
• Inspection: Check whether the expansion ring is damaged or worn to ensure that there are no defects affecting its use.

Installing wafers

• Placing the wafer: Gently place the wafer in the center of the expansion ring to ensure even contact between the wafer and the expansion ring.
• Alignment: Ensure that the wafer is aligned with the expansion ring to avoid offset or imbalance during processing.

Fixed ring

• Locking mechanism: If the expansion ring has a locking mechanism, ensure that it is fixed in place to provide stable support.
• Stability check: Confirm that the wafer is stable on the expansion ring and will not move or tilt during subsequent operations.

Packing and Shipping:

• The Wafer Hoop Ring will be securely packaged in a box, packed with bubble wrap or foam for extra protection.
• The box is then taped securely and labeled with the appropriate shipping information. It is then shipped via a trusted shipping company with tracking information provided.
