Soft-to-Soft Lamination(FF)

Paste the OCA film on the sensor function sheet, commonly known as soft-to-soft bonding.

The equipment used is generally a semi-automatic OCA attaching machine. The sensor is manually placed on the equipment table, and the isolation paper on the upper layer of the OCA is manually torn off (it can be pasted with a small piece of tape, which is more convenient), and the attachment is completed after the equipment is automatically aligned.

Material Characteristics

OCA is a kind of PSA (Pressure Sensitive Adhesive), which is a highly transparent optical adhesive and a pressure sensitive adhesive with a transmittance >99%.

The main factors affecting the paste effect are: surface roughness, surface contamination (grease, cleaning agent, water, dust, fibers, etc.), bonding time, pressure, temperature, etc.

The upper and lower protective films of the colloid are called release liner. When using, you must first tear off the light release layer and then paste an object, and then tear off the heavy release layer and paste it on another object.

The weight of the release (or release force), the force required to tear off the release layer (under unit length),

Of the two sides of the OCA, the one with the larger release force is the heavy release.

OCA film characteristics: good light transmittance (above 90%), good temperature resistance; excellent heat resistance, weather resistance, and good processability.

Lamination Method

For example, our products adopt the bonding method of metal grid FF, which is formed by bonding optical glue + Rx electrode and optical glue + Tx electrode.
