HRC48 - 55 Wafer Frame Ring Dicing Ring

Mechanical Polishing Glossy Ra<0.15um Hardness HRC48-55 Wafer Dicing Frame Ring ES-WFR-Dura420

1. Introduction of Mechanical Polishing Glossy Ra<0.15um Hardness HRC48-55 Wafer Dicing Frame Ring ES-WFR-Dura420

Wafer frame ring ES-WFR-Dura420 is made of German Dura420 high hardness stainless steel plate, which can ensure the right performance as wafer metal ring. It is also known or named as wafer frame, wafer mounting ring, wafer loading ring, wafer dicing ring, wafer metal ring, wafer ring frame or wafer frame ring.

Wafer frame ringES-WFR-Dura420 can provide safe support during the process of wafer or chip shipping and handling operations. Such wafer dicing ring is featuring extremely light weight and reliable shaping performance. We have many end users of wafer or chip producers globally around the world.

3. Application of Mechanical Polishing Glossy Ra<0.15um Hardness HRC48-55 Wafer Dicing Frame Ring ES-WFR-Dura420

EASTAR® Wafer frame ringES-WFR-Dura420 (also named as Wafer Dicing Ring/Wafer Metal Frame/Wafer Metal Ring/Wafer Ring Frame/Wafer Frame Ring) is working as a circular or special shape metal ring used to protect the edges of wafers and chips, mainly used in the laser marking process of wafers to provide protection and position limit. The wafer frame ring can withstand the high temperature and energy during the UV laser marking process to prevent chip damage and edge fragmentation.
