Wafer Mounting Ring - 420 Stainless Steel Wafer Frame for Semiconductor Dicing
Wafer Mounting Ring - 420 Stainless Steel Wafer Frame for Semiconductor Dicing
Product Description
The ZMSH Wafer Mounting Ring, also known as a Wafer Frame Ring or Dicing Ring, is a precision-engineered stainless steel frame designed for secure wafer handling in semiconductor manufacturing processes such as dicing, back grinding, polishing, bonding, and temporary transportation.
Manufactured from 420 stainless steel, the wafer mounting ring provides excellent rigidity, flatness, and dimensional stability. When used together with dicing tape or UV tape, it ensures reliable wafer fixation, minimizes vibration and slippage, and helps improve yield during high-precision wafer processing.
ZMSH wafer mounting rings are reusable and compatible with professional cleaning and refurbishment processes, making them a cost-effective and reliable solution for wafer fabs, OSATs, and semiconductor laboratories.

Frequently Asked Questions (FAQ)
1. What is the main function of a wafer mounting ring?
A wafer mounting ring is used together with dicing tape or UV tape to securely fix semiconductor wafers during processes such as dicing, back grinding, polishing, and bonding. It provides mechanical rigidity and dimensional stability, preventing wafer movement, vibration, and misalignment during high-precision processing.
2. Why choose a 420 stainless steel wafer mounting ring instead of plastic or resin rings?
Compared with plastic or resin rings, 420 stainless steel wafer mounting rings offer significantly higher rigidity, flatness stability, and wear resistance. They are better suited for high-speed dicing, repeated cleaning cycles, and high-precision semiconductor manufacturing where dimensional consistency and long service life are critical.
3. Can ZMSH wafer mounting rings be reused after cleaning?
Yes. ZMSH wafer mounting rings made from 420 stainless steel are designed to be reusable. With proper professional cleaning to remove tape residue, adhesive, and particles, the rings can be reused multiple times without affecting flatness or performance.
