[0002] Silicone parts, as the name implies, are accessories made of silicone material. The silicone parts have excellent electrical insulation and fatigue resistance, and are often used as auxiliary accessories for many electronic products. They need to be attached to electronic products before they can be used.

The adhesive usually consists of an adhesive material layer and an isolation film used to isolate the adhesive material layer from the external environment. It is convenient for consumers to tear off the isolation film on the adhesive, and then the silicone parts can be directly attached to the required electronic products. The adhesive of the silicone parts requires high attachment position accuracy and attachment flatness to meet the use needs of consumers.
