PSB-ICSP-1183-Rev A-ICSP Guard Column Consolidation

Background: 

To continue to improve our production capabilities, we have made scalability and production efficiency improvements to the following list of guard columns.  See table below.

In addition, changes have been made to the Quality Assurance Report (QAR).  Please be assured that this change does not affect the guard column form, fit or function. The new testing procedure has been thoroughly validated to ensure direct correlation with the previous testing procedure and high-quality standards.

These changes allow the Sunnyvale factory to further enhance standardization and efficiency, thereby increasing output and enabling faster delivery of guard columns to customers. Starting on November 1, 2025, customers can expect to receive guard column shipments made with improvements.

Scope:

See table in PSB.
