Adhesive Application On The Phone
With the continuous development of technology, the design and manufacturing of mobile phones are increasingly pursuing ultra-thin, ultra-light, and three-dimensional beauty. Ultra-thin, touch-screen, and smart phones have become the latest consumer favorites. In order to achieve a gapless and flat appearance, more and more adhesives are used to bond and fit components during the assembly process of mobile phones.
The main adhesive points for mobile phone adhesives are as follows:
- 1. Glue for motherboard: Glue for mobile phone motherboard includes: chip bonding, potting, heat dissipation; battery bonding; bonding of components on the motherboard, etc. The main glues used are: epoxy adhesives, thermally conductive adhesives, organic silicone adhesives, spot welding adhesives, UV adhesives, acrylic adhesives, etc.
- 2. Glue for shell: Glue for bonding mobile phone shell: polyurethane hot melt adhesive, acrylic resin adhesive, reactive hot melt adhesive
- 3. Glue for screen and frame: polyurethane hot melt adhesive, UV adhesive, reactive hot melt adhesive, acrylic adhesive, high temperature resistant adhesive.
- 4. Glue for LOGO: hot melt pressure-sensitive adhesive, silicone adhesive, self-adhesive, acrylic resin adhesive.
- 5. Glue for fixing mobile phone cameras (glue for bonding mobile phone lenses and bases): UV glue, OCA optical glue
- 6. Glue for bonding the side buttons of the mobile phone (volume button, power button): UV glue, quick-drying glue
- 7. Bonding of FPC antenna and housing (bonding of mobile phone antenna and housing): self-adhesive, UV adhesive, pressure-sensitive adhesive
- 8. Glue for camera module (between Holder and FPC on camera module, FPC bending area): UV glue, quick-drying glue, epoxy resin glue, organic silicone adhesive
- 9. Glue for the sound box cover (the cover of the sound box in the mobile phone): UV glue, instant glue, hot melt glue, epoxy resin glue, organic silicone adhesive
- 10. Glue for motor connection (fixing flat motor connection of mobile phone): acrylic resin adhesive epoxy resin adhesive
Introduction to several adhesives:
- 1. UV glue
Introduction: UV glue has various types, dries quickly under ultraviolet light, has fast deep curing speed, can be used for a wide range of bonding materials, has high bonding strength, can be used as a coating for circuit boards, is suitable for automated operations, and greatly improves efficiency.
- 2. Reactive polyurethane hot melt adhesive
Introduction: PUR reactive polyurethane hot melt adhesive, one-component solvent-free hot melt structural adhesive, high bonding strength, good heat resistance and solvent resistance, good wear resistance and water resistance, suitable for bonding various plastics and suitable for bonding in the electronics field.
- 3. Instant Adhesive
Introduction: Single component, high bonding strength cyanoacrylate adhesive, has good bonding to a variety of substrates. It has a very fast curing speed, can cure under harsh conditions, quickly complete the bonding process, and also has good bonding to some difficult-to-bond materials.
