Workpiece Description: Before cleaning, hardened ACF residues can be clearly seen on the panel appearance.

Using the old ACF removal gel cannot be effectively removed.

Find new potions. It was found that the hardened polyimide cleaner PIC06 embrittles the remaining ACF and can be removed with a plastic scraper.

The hardened polyimide cleaner PIC06 is liquid and needs to be gelled so that it does not run around.
At the same time, we continue to search for more effective medicines. However, test artifacts are required, and the customer should provide them.

The customer provides a new sample, the ACF residue looks different from the old model, the appearance is as follows.

Gel the hardened polyimide cleaning agent PIC06 to make ACF removal gel PIC06-G.
It is found that PIC06-G can effectively remove the residual glue of this ACF.

At the same time, we tested the old ACF removal gel ACHM04-AG, and found that ACHM04-AG can also effectively remove this ACF residue.
The adhesive removal methods of the two agents are different. PIC06-G embrittles the residual adhesive, which can be scraped off with a plastic knife. ACHM04-AG swells and softens the residual glue, which can be wiped off with a dust-free cloth.
