Glue dispensing refers to a process of industrial production of electronic products, that is, applying, filling, and dripping white glue, UV glue, red glue, etc. on the product to play the role of reinforcement, sealing, insulation, etc. The purpose of doing this is mainly to provide moisture-proof and heat-conducting functions for electronic boards and some important electronic components to better protect these sensitive components. It can be seen that glue dispensing not only makes product quality more stable, but also improves the brand reputation of mobile phones.

Chip glueing means that after the processor is installed on the motherboard, a layer of electronic glue is used to reinforce it. It also has the function of shielding electromagnetic interference, preventing deformation due to air or external force, which may cause the chip pins to desolder and cause mobile phone failure. On mobile phones, the welding between the processor and the motherboard is not 100% reliable. When the mobile phone is bumped or dropped, the motherboard and the processor may become loose, causing problems with the mobile phone. Gluing is equivalent to adding another layer of insurance.

The purpose of gluing the mobile phone screen and frame is to bond the rear screen of the mobile phone to the frame. Accumulation will cause excess glue to overflow or stick to the circuit board, causing hidden problems. Leaking glue will cause gaps between the frame and the rear screen, which may allow dust and water stains to penetrate.
