REQUIREMENTS FOR THE PROCESS CAPABILITY APPROVAL - FOR MANUFACTURING LINES OF HERMETIC HYBRID MICROCIRCUITS - ESCC Basic Specification 2566000 - Issue 3

Aug 30, 2026

Upload by Violet

Defines the requirements for Process Capability Approval (PCA) of manufacturing lines producing hermetic hybrid microcircuits intended for space application. Specifies how a manufacturer must be evaluated and capability approved for a defined set of materials and processes, including description and publication in REP007 (ESCC List of PCA certificates). Applies to substrate and interconnect technologies and must be read with ESCC Basic Specification 25600. Excludes non-hermetic device manufacturing line PCA needs.

FAQs

What is the purpose of this specification for PCA?

It defines the requirements for Process Capability Approval of a manufacturing line of hermetic hybrid microcircuits intended for space application.

Which topics does the evaluation cover before PCA is approved?

It covers manufacturer evaluation, evaluation of the process capability domain, evaluation test programme and testing, and the manufacturer’s audit.

What is the PCA phase and how are processes approved?

The PCA phase specifies PCA testing requirements, including test vehicles, PCA test plans, methods and conditions, and the PCA test report, plus specific procedures for hybrid manufacturing lines.

Does this specification apply to non-hermetic devices?

No. It does not provide requirements for PCA of a manufacturing line of devices not designed to be hermetic.
