[0016] The present invention will be further described below in conjunction with specific embodiments:
[0017] The method for detecting FPC high Tg adhesive substrates of the present invention mainly includes the following steps:
[0018] (1) Carry out aging test on FPC high Tg rubber substrate.
[0019] The test conditions of the aging test: the aging temperature is 120℃, and the aging time is 2h. The first aging is the pretreatment of thermal shock, constant temperature and humidity, and high temperature storage test.
[0020] (2) Carry out thermal shock test, constant temperature and humidity on FPC high Tg plastic substrate. Test, high temperature storage test.
[0021] Test conditions for thermal shock test: low temperature impact temperature is -42~-38℃, low temperature impact time is 30min; high temperature impact temperature is 123~127℃, high temperature impact time is 30min; the number of impacts is 500 times for high and low temperature, low temperature The transition time...
