Workpiece description: Before the OGS is cut into single pieces by CNC, it is protected with peelable glue to avoid pollution. After cutting and peeling off the peelable adhesive, only to find that there is a ring of residue along the outer edge of the peelable adhesive that needs to be cleaned.
-
Before washing, look front and back.
-
After the peelable adhesive is torn off, irradiate it with a strong light (full-spectrum halogen lamp) in a clean room, and you can clearly see a circle of residue along the outer edge of the peelable adhesive.
-
Clean with AHLR03-GU cleaning agent for 240 seconds at 80°C, 40KHz, 50W/L ultrasonic waves.
It was found that most of the residual glue/residue was removed.
-
But you can still see some slight traces on the OGS (similar to the traces of liquid flow or water marks), these traces have existed before cleaning, and cannot be removed after cleaning. (The photo on the left below is AHLR03-GU before cleaning, and the right is after cleaning)
-
Clean with dust cleaning agent PTC09-B at 65°C, 40KHz, 50W/L ultrasonic wave for 120 seconds.
It was found that the remaining traces were also cleaned.
