REQUIREMENTS FOR THE PROCESS CAPABILITY APPROVAL FOR MANUFACTURING LINES OF HERMETIC HYBRID MICROCIRCUITS - ESCC Basic Specification No. 2566000 - Issue 2 - November 2014

Aug 30, 2026

Upload by Skyler

Defines requirements for Process Capability Approval (PCA) of manufacturing lines for hermetic hybrid microcircuits intended for space applications. Specifies how manufacturers are evaluated and capability-approved for defined sets of materials and processes, including how the capability is described and published in the ESCC PCA certificate list. Applies to substrate and interconnect technologies and must be read together with ESCC Basic Specification 25600, which sets general PCA requirements, while excluding non-hermetic device manufacturing lines.
