D07400 - SEMI D74 - Guide for Measuring Dimensions of Plastic Films/Substrates StdPbc-0820 It is so different thatPlastic films substrates for flexible displays change their dimensions by temperature and humidity. Also their dimensions will change by time after heat treatment, water treatment, etc. This Standard provides procedures for the measurement environmental condition to measure dimensions of plastic films substrates. This Standard provides guidance for measuring dimensions of plastic films substrates for electronic devices. Referenced SEMI Standards
