Dura420/SUS420J2 Stainless Steel HRC48-55 Surface Hardness Wafer Dicing Ring Frame Ring ES-WFR
1.Introduction of Dura420/SUS420J2 Stainless Steel HRC48-55 Surface Hardness Wafer Dicing Ring Frame Ring ES-WFR
EASTAR® wafer frame ring (also named as Wafer Dicing Ring/Wafer Metal Frame/Wafer Metal Ring/Wafer Ring Frame/Wafer Frame Ring) is professionally designed and produced by EASTAR engineering team.
EASTAR® wafer frame rings are the preferred solution rings because they are ergonomic and can provide safe support during wafer or chip shipping and handling operations. They are featuring extremely light weight and reliable shaping performance. We have many end users of wafer producers globally around the world.

2. Application of Dura420/SUS420J2 Stainless Steel HRC48-55 Surface Hardness Wafer Dicing Ring Frame Ring ES-WFR
EASTAR® wafer frame ring (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.
