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 machine

 Preservation methods 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.
