Today we discuss the ACF which be used in flex change
process, the information may not so detailed or completed, just for your
reference and welcome to join the discussion.
Here are two
types of ACF we often meet, one is Hitachi (AC), the other is Sony (CP),
Hitachi (AC) is general using in our industry. ACF is an anisotropic conductive
adhesive, there is small metal ball inside the adhesive, the up and down metal
balls will touch and form a circuit conduction during the pressing process. The
most commonly used place is the connection place between LCD glass and driver
IC / FPC. Vacuum laminating
and the use of the period for ACF:
1, Unopened ACF, storage conditions: -10 ~ 5 ?, the use of the period after the
manufacture of four to six months (the date of manufacture and
preservation of the ACF trademark will be marked).
2, The opened ACF
preservation conditions: -10 ~ 5 ?, the use of the period of SONY (CP) 15 days, Hitachi (AC) 30-60 days.
3, Opened products,
such as bare in the air, the preservation time is only 7 days; unopened
products stored in the high-temperature environment will shorten the effective
use of its period. General 7 days at room temperature and high-temperature
environment will cause the active factor fail.
