JetStep® S3500 System

Designed to provide OSATS  with a lithography solution capable of high volume manufacturing of panel-level packaging.

Product Overview

The JetStep S3500 panel lithography system is designed specifically for advanced packaging panel production. The system incorporates advanced features that address requirements for panel-level packaging, such as die shift due to placement accuracy or subsequent processing steps, CTE mismatch, panel warpage and panel handling. It incorporates the largest available exposure field with resolution capability to 2/2 and options for increased resolution to 1/1.
