SUS420J2 Stainless Steel Material Inner circular shape Wafer Metal Ring Special Shape Metal Ring Protect Edges Of Wafers And Chips ES-WFR-SUS420
1. Introduction of SUS420J2 Stainless Steel Material Inner circular shape Wafer Metal Ring Special Shape Metal Ring Protect Edges Of Wafers And Chips ES-WFR-SUS420
Wafer frame ring ES-WFR-SUS420 is made of SUS420J2 high hardness stainless steel plate, which can ensure the right performance as wafer metal ring.
SUS420J2 is a martensitic stainless steel with excellent mechanical properties and corrosion resistance, widely used in industrial fields. Its chemical composition and physical properties endow it with good comprehensive performance, and the heat treatment process has a significant impact on its performance.
SUS420J2 is a material defined in the Japanese Industrial Standards (JIS) and belongs to the 420 series stainless steel. It has high hardness, strength, and wear resistance, and also has good corrosion resistance under certain conditions.

3. Application of SUS420J2 Stainless Steel Material Inner circular shape Wafer Metal Ring Special Shape Metal Ring Protect Edges Of Wafers And Chips ES-WFR-SUS420
Wafer frame ring ES-WFR-SUS420 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.
EASTAR® Wafer frame ring ES-WFR-SUS420 (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.
Such product 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.
