DIN EN IEC 63251:2024-07

This International Standard defines the thermal endurance test methods for reliability assessment of flexible opto-electric circuit boards. The purpose of this standard is to accommodate the uniform thermal characteristics required by the flexible opto-electric circuit in high temperature environments such as automobiles. In particular, this standard specifies a test method to inspect the occurrence of color exchange, deformation and delamination of flexible opto-electric circuit boards under thermal stress. There are no restrictions on the scope of application of this document. The application of this document increases investment security for manufacturers and users, provides test laboratories and manufacturers with defined specifications for testing, and ensures compatibility across manufacturers.
