METHOD FOR DETECTING DEGREE OF BALANCE OF PRESSURE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for detecting the degree of balance of a pressure device that can correctly measure the degree of balance by matching a pressure distribution with a coloration distribution by using pressure-sensitive paper at actual heat pressing temperature above the upper-limit temperature that the pressure-sensitive paper allows. SOLUTION: A polyimide film 4 of uniform thickness with followability is interposed between the pressure-sensitive paper 6 mounted on a mount base 2 and a heater bar 5. COPYRIGHT: (C)2004,JPO
