Application Areas

• Semiconductor wafer cassette systems: Used as support cables for positioning wafers or signal transmission components.
• High-cleanliness automated equipment: Mechanical movement, stretching, and support applications in cleanroom environments.

Usage Guidelines

• Operation: Always wear cleanroom gloves. Avoid contact with skin oils or contaminants. Hold by the ends whenever possible.
• Installation: When installing PEEK support cables, avoid excessive force or twisting to prevent damage. Install the support cables accurately according to the cassette design requirements to ensure secure installation.

Maintenance

Under normal operating conditions, inspection items include:

• Inspection: Regularly inspect the wear condition, surface integrity, and connection stability of the support line. If severe wear, breakage, or loosening is detected, replace the support line promptly to ensure normal equipment operation.
• Temperature: Do not exceed the specified continuous operating temperature for the PEEK grade. Avoid rapid thermal cycling whenever possible.
• Cleaning: Before and after use, it is recommended to clean the support lines with a clean, lint-free cloth or specialized cleaner to remove any dust or debris on the surface. However, avoid using cleaners that are corrosive to PEEK material.
