Double-sided adhesive tape 3800 series for fixing LCD components

1Strong adherence

CheckTest of adherence to FPC bending part

• Stick a piece of tape to the FPC and stick it to another board with the part bent.
• With the part bent, leave it for 24 hours at 85°C and check the visual appearance.

SEKISUI product: ◎ No lifting or peeling of the tape

Competitor’s product: Lifting of the tape

SEKISUI products stick well to the bending part of an FPC even in high temperatures, reducing misalignment of the LED optical axis from tape lifting.

2Excellent anti repulsion property

CheckTest of PI bending (anti repulsion) substitute

• Stick a 2 mm×20 mm piece of double-sided tape to a PC board (1 mm thick).
• Attach PI film in tape form (0.05 mm thick) and apply pressure back and forth once with a 2 kg roller.
• Let the film sit for three hours at 23°C, 50%RH to cure.
• Bend the PI film and fix it to the back of a PC board with double-sided tape to test the adhesion between tape and PI film.

SEKISUI products exert adhesion properties that reduce PI film repulsion even in hot environments.

3Highly light shielding

Observation

SEKISUI

Light completely blocked

Competitor A

Using a strong light source
results in pinholes

Competitor B
