Automotive PPAP & PCB Cleaning Validation
PPAP (Production Part Approval Process) requires evidence that production processes produce parts meeting design and quality standards. Cleaning validation is often part of PPAP documentation for electronic assemblies in automotive supply chains.
-
include cleaning procedures in PPAP packages
-
provide analytical evidence of residue control
-
process capability indices and control plans demonstrate stability
-
supplier audits and traceability support PPAP acceptance
Understanding PPAP standards
PPAP drives supplier validation to ensure consistent production output. For electronics, PPAP documentation may include cleaning SOPs, validation runs, and test results demonstrating that parts meet claimed cleanliness levels.
Validation methods in automotive cleaning
Validation uses sample lots, analytical testing (ion chromatography, TOC, particulate counts), and capability analysis. ZESTRON helps suppliers generate PPAP-ready cleaning validation packages and on-site training to meet OEM expectations.
