CY9500 Quartz Disc Dia. 50.8 mm x 1.6 mm, Polished

Quartz Disc Dia. 50.8 mm x 1.6 mm, Polished Description

This quartz (SiO₂) disc has a diameter of 50.8 mm and a thickness of 1.6 mm. The polished finish is achieved through sequential lapping and chemical mechanical planarisation, ensuring an optically flat surface. Its precisely defined dimensions allow compatibility with semiconductor device fabrication and metrology equipment. The controlled surface properties and verified chemical purity reduce potential contamination during subsequent processing steps.

Quartz Disc Dia. 50.8 mm x 1.6 mm, Polished Packing

The disc is individually packaged in an electrostatic discharge-protected container with custom foam inserts to minimise mechanical impact. It is sealed in an anti-contamination pouch and stored under controlled ambient conditions to avoid moisture uptake. Packaging instructions detail proper handling measures. Custom packaging options, including vacuum sealing and specialised labelling, are available upon request.

Frequently Asked Questions

Q1: How does the polished surface affect subsequent processing steps?
A1: The polished finish is verified using interferometric methods, which minimises surface irregularities. This accurate surface profile ensures even thin film deposition and reduces scattering issues during device fabrication.

Q2: What quality control techniques are implemented during production?
A2: The discs undergo interferometric surface evaluation and microscopic inspection. These measures verify flatness and dimensional tolerances, helping to reduce variability and support integration into high-precision manufacturing workflows.

Q3: What are the recommended storage conditions for the quartz disc?
A3: It is advisable to store the disc in a clean, temperature-regulated environment with static-protected packaging. Low humidity and minimal particulate exposure are essential to maintain the disc's surface integrity and chemical stability.
