This field requires high precision and stability in adhesive supply to avoid short circuits or component detachment caused by adhesive quantity deviation. In the PCB board bonding, IC packaging, and bonding processes, it can correctly transport epoxy adhesive and other packaging adhesives, achieve 0.01ml level micro dispensing, ensure no bubbles at the packaging site, uniform adhesive layer, and prevent external moisture and dust from corroding chips and circuits; For the chip bottom filling process, the bottom filling adhesive can be stably transported to fill the small gaps between the chip and the substrate, improve the chip's impact resistance and heat dissipation ability, and avoid virtual soldering of the chip due to vibration or temperature changes; It can also be used for bonding micro components such as resistors and capacitors on circuit boards, as well as for sealing electronic components such as relays, capacitors, and transformers, enhancing the firmness and electrical performance stability of the connection between components and substrates.
2. In the field of consumer electronics manufacturing
Adapt to the production of miniaturized and high-precision consumer electronics products such as mobile phones, laptops, and headphones. For example, in the packaging of mobile phone and laptop batteries, it is possible to apply sealant correctly, which can prevent battery leakage and provide buffering protection to avoid external impact damage to the battery; For the speaker of headphones and the receiver of mobile phones, the coil can be glued and fixed, and the outer ring of the speaker can be bonded to ensure the stability of the sound emitting components and reduce sound quality distortion; In addition, in the frame sealing of display devices such as PDAs and LCDs, the amount of adhesive can be controlled to overflow evenly, achieving good sealing effect and preventing water vapor from entering and affecting the display screen.
3. LED and optoelectronic display field
The dispensing process in this field directly affects the luminescence performance and service life of the product. In the production of LED beads, it is necessary to correctly apply fluorescent adhesive in small areas. The double tube precision screw valve can ensure consistent adhesive amount and uniform adhesive layer thickness for each bead through closed-loop control, ensuring uniform LED light emission and avoiding brightness differences caused by adhesive deviation; When bonding LED lenses, the adhesive can be correctly delivered to firmly fix the lens and lamp holder, while avoiding glue contamination that affects the transparency of the lens; In addition, in the processes of filter assembly and lens bonding of the camera module, the tiny adhesive lines can be controlled to ensure the assembly accuracy of the optical components, thereby ensuring the imaging quality.
4. Automotive electronics field
Automotive electronics have strict requirements for sealing and shock resistance, and this series of equipment can meet the production needs of various components. For example, in the packaging of electric vehicle controllers, the glue filling process is used to isolate dust and moisture, ensuring stable operation of the controller under complex vehicle conditions; As the core sensing component, automotive sensors require internal electronic components to be sealed and protected. The screw valve can correctly deliver the sealing adhesive, allowing the sensor to resist vibrations and high and low temperature changes during vehicle operation, ensuring accurate detection data; At the same time, it can also be used for bonding and packaging car lights, preventing water ingress and fogging of the lights, ensuring long-term stable light emission of the lights, and can also be used for sealing car instruments to enhance their durability in harsh car environments.
